まずは今やグランドセイコーの代名詞にもなった、自然の情景を表現する文字盤から見ていこう。

ブランドの顔とも言えるムーブメントを祝すモデルとだけあり、SBGH311もSBGR325も非常に凝った内容だ。まずは今やグランドセイコーの代名詞にもなった、自然の情景を表現する文字盤から見ていこう。

SBGH311のダイヤルモチーフとなるのは、グランドセイコースタジオ 雫石からも姿を臨むことのできる岩手山に広がる雲海だ。この有機的なパターンは、いわゆる白樺文字盤で見られた型打ちではなく、メッキ技術を活用したものである。そのため、ガガミラノ スーパーコピー意図的に加えられた目の粗さは箇所によって微妙に異なっており、結果、光の当たり方によって文字盤の表情が変わっていく。

対するSBGR325の文字盤は、岩手山の山頂から見上げる中天、つまり空を表したものだ。目を引くスカイブルーはラッカー塗装ながら、蒸着系の着色と見間違うくらいにサンレイ仕上げのニュアンスがよく出されており、空気の澄んだ岩手県の青空を魅力的に表現している。近年、アイスブルー系の文字盤を多く手掛けているグランドセイコーだが、その着色はどれもラッカーだ。しかし塗料はもちろん、ベースのパターン付けや下地処理で差別化を図ることで、独自の個性を得ることに成功している。

ムーブメントを見ていこう。SBGH311が採用するのは3万6000振動／時のハイビートムーブメント、Cal.9S85だ。グランドセイコーがもち続ける“高精度”のイメージを牽引してきた10振動機は、ローターに獅子のエンブレムがあしらわれた限定デザインに変更。さらに陽極酸化処理によって、雲海の上に広がる空をイメージしたスカイブルーに着色した。 ガガミラノ マニュアーレ48mm 手巻き スモールセコンド レザー ダークブルー/シルバー メンズ 5510.1 N品価格：23600円 ケース ステンレス×カーボン バンド素材 レザー/牛革 防　水 日常生活防水 ガラス ミネラルガラス 時計サイズ 約H48×W48×D13mm 腕周り 約17.5～22.0cm　7穴 ムーブメント 手巻き スモールセコンド 保証期間 当社規定1年間

華やかさもありながら、派手になり過ぎない上品さも漂わせています。

秋の優しい夕陽に染まるセイコーハウスの石壁。その色彩からインスピレーションを得た、薄いピンクがかったオレンジ色の文字盤が特徴です。文字盤にほどこした縦横の繊細な筋目パターンがほのかに陰影を演出し、夕陽の光と影を表現しています。太陽の輝きを思わせるゴールドカラーのGSロゴと秒針も夕陽色の文字盤によくなじんでいます。 「グランドセイコー ヘリテージコレクション メカニカルハイビート 36000 和光限定モデル 2024 SBGH357」の文字盤は、見る角度によって、オレンジにもピンクにも見える、まさに夕陽に染まる空色をそのまま映したかのような絶妙なカラーリング。華やかさもありながら、派手になり過ぎない上品さも漂わせています。

GSロゴ＆秒針は太陽の輝きを思わせるゴールドカラーで、夕陽色の文字盤に自然と馴染んでいますね。文字盤表面に施された繊細な筋目模様が、うっすらとした陰影を生み出し、ニュアンスカラーをより一層引き立てています。

1967年に発売されたグランドセイコー史上初の自動巻機械式モデル「62GS」を現代的にアレンジした「62GS現代デザインモデル」です。ベゼル（ガラス縁）のない構造によって広々と見える文字盤や、ザラツ研磨という技法によってシャープな多面体で構成されたケースフォルムが印象的です。 ケース形状はヘリテージコレクションの「62GS」系。二十四節気をテーマとしたモデルが多く製作されており、今年は38mmの“桜隠し”SBGH341＆“桜若葉”SBGH343なども話題となっているラインですね。

ムーブメントは、「グランドセイコースタジオ 雫石」で組み立てられた10振動のメカニカル・キャリバー9S85を搭載しています。10振動ムーブメントは、機械式時計の精度を司る「てんぷ」が1秒間に10回振動し、これを1時間に換算すると36,000回になるところから、”ハイビート36000”と呼ばれています。振動数が多いほど外乱の影響を受けにくく、より安定した精度を得ることができるのです。 ちなみに今回の限定数量の85本、という数字は、搭載するムーブメント「9S85」にちなんだものです。

Inspired by Mt. Iwate’s sea of clouds One of the commemorative watches is graced by a silver dial whose texture and colour evoke the sight of the sea of clouds that cover Mt. Iwate in Iwate Prefecture, where all Grand Seiko mechanical watches are manufactured. This scene is only visible at daybreak, when the air is so still and humid that dense clouds overlap to create a beautiful silvery-white sea. Through the clear sapphire crystal case back, the Grand Seiko emblem is easily visible, set into the titanium oscillating weight whose colour was created especially for this watch to suggest the deep-blue sky above the sea of clouds that so often surround Mt. Iwate’s peak. This colour is made possible by an anodic oxidation process.* *Anodic oxidation treatment This is a surface treatment in which metals are subjected to electrolysis so as to generate artificially an oxide film. Titanium oxide film produces colour according to the light refraction index, enabling the production of different colours by varying the thickness of the oxide film. This new creation is equipped with the Hi-Beat 36000 automatic mechanical Caliber 9S85, which is hand assembled by the skilled craftsmen and women of the Grand Seiko Studio Shizukuishi. It has an accuracy rate of +5 ~ -3 seconds per day and delivers a power reserve of 55 hours. A limited edition of 1,200, this watch will initially be exclusive to Grand Seiko Boutique Online, starting in January 2023, and then will be available at the Grand Seiko Boutiques and select retail partners worldwide in February 2023. https://www.instagram.com/p/CnUJVfxLRN6/?igshid=NGJjMDIxMWI=

Birth of Grand Seiko

  Grand Seiko SBGA011 with 9R Spring Drive movement

Prior to 1960, to challenge the status of Swiss watches and change the perception of Japanese watches, Daini Seikosha and Suwa began the discussion of a product line that can match the quality of Swiss watches under the suggestion of the parent company. At the time, Suwa Seikosha Co. was in charge of manufacturing men's watches, so it was decided that Suwa would be producing the first Grand Seiko (GS).

  The first Grand Seiko was released in 1960, it was based on Seiko's previous high-end watch, CROWN. This Grand Seiko has a 25-jewel, manual-winding, 3180 calibre, and only 36,000 units were produced. This was also the first Chronometer grade watch manufactured in Japan, and it was based on Seiko's own chronometer standard.

  Design style

The design language of the Grand Seiko was set in 1967, with the creation of Grand Seiko 44GS. The 44GS set the ground for all future Grand Seiko with nine elements. These elements help improve the legibility of the watch under different situations, and create a sharp, crisp visual impression:

  Double width index at 12 o'clock

Multi-faceted rectangular markers

Highly polished bezel

Highly polished planes and two-dimensional surface

Half recessed crown

Flat dial

Multi-faceted hour and minute hands

Curved side line

Reverse slanted bezel wall and case side

Dress style with simple but beautiful design

Mechanical movement

In 1968, Seiko introduced three 10 beat (10 ticks per second) calibers, the automatic caliber 61GS, the manual winding 45GS and 19GS for women's watch. The 61GS was Japan's first automatic 10 beat watch, and it was the most accurate mechanical watch due to the high beat calibers. The calibers are considered high beat because normal mechanical movements beat six to eight times per second, and higher beat makes the watch more resistant to shock, thus achieving the high accuracy.

  In 2009, Seiko released the new 10 beat caliber 9S85, which is a completely new designed of the previous high beat caliber. The new caliber also met the Grand Seiko Standard, a chronometer certification that the company claims to be more strict than the Chronometer Certificate in Switzerland.

Grand Seiko 60th Anniversary Limited Edition SBGH281 Watch

BY DHANANJAY PATHAK

While 2020 would sadly be remembered as the year of the Coronavirus pandemic, it also happens to mark the 60th anniversary of Grand Seiko. To commemorate this special occasion, Grand Seiko released watches such as the cutting edge SLGH002 and the bold looking SLGA001 earlier this year. And now, the celebrations continue with the SBGH281, which we already covered briefly. This new limited-edition watch features a deep blue dial and is powered by the brand’s in-house true high beat movement.  

Grand Seiko watches have always been known for their exceptional dials and the SBGH281 is no different. The inky blue dial has a lot of depth to it and provides the perfect backdrop for all the other elements. The hour index comprises highly faceted batons that add a nice of depth to the dial and have been exceptionally finished in true grand Seiko style to offer great light reflectivity. The sword-shaped hour and minute hands look razor-sharp and are well proportioned to make sure that time is easily readable in most circumstances. The stick style second’s hand has been painted red and along with the “Automatic” and “Hi-Beat 36000” text at 6 adds a nice pop of color to the dial.  

The case on the SBGH281 has been crafted from stainless steel and features the famous 44GS style silhouette. It measures 40mm in diameter and has a thickness of around 13.3mm. Like the dial, it is the execution and finishing of the case that makes this watch special. The case features a nice blend of finely brushed and mirror-like polished surfaces that are achieved using a technique called “Zaratsu”. Thanks to a threaded crown at 3, the case is water-resistant to a healthy 100 meters, making this a capable everyday watch.  

Powering the SBGH281 is Grand Seiko’s in-house caliber 9S85. This is an automatic movement that operates at a frequency of 5 Hz and offers an ultra-smooth sweep of the second’s hand. The movement has been fine-tuned to be accurate within -3 to +5 seconds a day and offers a power reserve of around 55 hours when it’s fully wound. It has been nicely decorated using Tokyo stripes but is only partially visible through the sapphire case back thanks to the Grand Seiko’s line and the 60th-anniversary text.  

The Grand Seiko 60th anniversary limited edition reference SBGH281 is accompanied by a stainless steel bracelet. The production run is limited to 1500 pieces and the watch would retail for USD 6,300.

REVOLUTION: Grand Seiko SBGM235G 9S Mechanical 20th Anniversary Limited Edition 

Grand Seiko encompasses a full spectrum of contemporary watchmaking united by the single, simple principle: that every GS model is the best the company can sustainably make. In mechanicals, quartz and the electro-mechanical hybrid unique to the company that is the Spring Drive, a watch that wears the GS logo is the pinnacle achievement of Seiko’s considerable resources in terms of industrial process, human craftsmanship, corporate resolve and technical ingenuity; in Seiko’s own words, a Grand Seiko is nothing less than “the ultimate practical watch”.

The SBGM235G is part of a flurry of Grand Seiko models that Seiko released to mark the 20th anniversary of its 9S self-winding movement which forms the base upon which mechanical Grand Seiko watches are built, from time-only to complication models. Limited edition watches released thus far to celebrate the 9S include three-hand date models in platinum, gold and steel featuring the cal. 9S85, a high beat variant of the 9S beating at 5hz, and a ladies watch driven by a thinner version of the 9S, the cal. 9S25...

Seiko ra mắt 3 mẫu đồng hồ Hi-Beat 3600 nhân dịp 20 năm ra đời bộ máy Caliber 9S

Nhân dịp kỷ niệm 20 năm ra đời bộ máy Caliber 9S, hãng sản xuất đồng hồ Seiko đã cho ra đời 3 mẫu đồng hồ Hi-Beat 3600 với thiết kế vô cùng đặc biệt và sang trọng

Chiếc đồng hồ Grand Seiko đầu tiên ra mắt vào năm 1960 cùng với bộ máy 9S, và đã đánh dấu mốc quan trọng trong lịch sử của thương hiệu này. Được thiết kế với độ chính xác cao và độ bền tuyệt vời, bộ máy Caliber 9S theo thời gian cũng được cải tiến liên tục: Từ hợp kim Spron mới đến kỹ thuật MEMS - một kỹ thuật cho phép các bộ phận chính được sản xuất với giá trị sai lệch chỉ bằng một phần nghìn milimet.

Ba mẫu Đồng hồ Seiko Hi-Beat 3600

Hi-Beat 36000 V.F.A ref. SBGH265

Ngày nay, 9S là nền tảng cho toàn bộ bộ máy của Grand Seiko và đã trở thành một trong những bộ máy tốt nhất thế giới nhờ độ chính xác cao, khả năng dự trữ năng lượng dài và kết cấu mạnh mẽ.

Hi-Beat 36000 V.F.A. với bộ vỏ platinum, được sử dụng lần đầu tiên vào năm 1969, V.F.A - viết tắt của từ “Very Fine Adjusted” (tạm dịch: “Được tinh chỉnh cực kỳ chuẩn xác”) định rõ những chiếc đồng hồ Grand Seiko được điều chỉnh rất khéo léo đến mức đạt được tỷ lệ chính xác vượt xa tiêu chuẩn Grand Seiko.

Mẫu Hi-Beat 36000 V.F.A. (ref. SBGH265) có tỷ lệ chính xác phi thường nhờ sở hữu bộ máy Caliber 9S85 Hi-Beat 36000 với mức sai lệch -1/+3 giây mỗi ngày, thông số này đạt được bởi mức điều chỉnh cao nhất và chương trình thử nghiệm kéo dài đến 34 ngày. Đồng hồ này được bao bọc bởi bộ vỏ có kích thước 39,5 mm từ platinum 950, đây là một sự đổi mới trong thiết kế của Grand Seiko, tạo ra bởi Nobuhiro Kosugi - nhà thiết kế chiếc đồng hồ 9S đầu tiên vào năm 1998.

Hai bề mặt đồng hồ được đánh bóng với kĩ thuật zaratsu mở rộng đến rìa của càng nối dây, nơi bề mặt cong kết nối với kĩ thuật chải xước cùng tạo ra một hình tam giác hoàn hảo. Mặt đồng hồ cũng thực sự đặc biệt, là sự kết hợp của các dấu hiệu đặc biệt được sử dụng để chỉ rõ đồng hồ được thực hiện bởi nhóm nghiên cứu tại Daini Seikosha (công ty hiện được gọi là Seiko Instruments Inc., từng phát triển đồng hồ hi-beat Grand Seiko đầu tiên vào năm 1968).

Hi-Beat 36000 V.F.A. là phiên bản giới hạn 20 chiếc. Đồng hồ này đi kèm dây đeo cá sấu với khoá gập ba lần có nút bấm để mở khoá và giá bán lẻ đồng hồ ở châu Âu là 53.500 EUR.

Hi-Beat 36000 Special ref. SBGH266 Gold 18K

Hi-Beat 36000 Special (SBGH266) có bộ vỏ kích thước 39,5 mm từ vàng 18k, trong khi chiếc Hi-Beat 36000 được làm từ thép không gỉ. Cả hai chiếc đồng hồ đều có chung thiết kế bộ vỏ như phiên bản V.F.A., cùng được trang bị caliber 9S85 và chung thiết kế mặt số.

Hướng dẫn thay dây da cho đồng hồ kim loại

Tuy nhiên, phiên bản vàng được điều chỉnh theo tiêu chuẩn đặc biệt Grand Seiko và có tỷ lệ chính xác từ +4 đến -2 giây mỗi ngày. Giống như phiên bản V.F.A., Hi-Beat 36000 Special (SBGH266) cũng sở hữu bánh lắc mang biểu tượng sư tử Grand Seiko từ vàng 18k là biểu tượng của độ chính xác cao.

Hi-Beat 36000 (ref. SBGH267 Steel

Phiên bản bằng thép không gỉ cũng có chi tiết bánh lắc đặc biệt, được làm từ titanium và vonfram, bề mặt titanium có màu xanh dương là kết quả của quá trình oxy hóa anốt (trong đó kim loại phải chịu điện phân để tạo ra một màng oxit giả, cho phép sản xuất các màu khác nhau bằng cách thay đổi độ dày của màng oxit.)

Được trang bị dây đeo cá sấu với khoá gập ba lần, Hi-Beat 36000 Special là phiên bản giới hạn 150 chiếc. Giá bán lẻ đề xuất của đồng hồ ở châu Âu là 27.000 EUR.

Phiên bản Hi-Beat 36000 thép không gỉ kết hợp dây kim loại bằng thép. 1500 chiếc sẽ được sản xuất và bán với giá 6.300 EUR.

Jaferson Holdings Corporation more commonly known simply as Jaferson is a Bangladesh holding company that holds subsidiaries which manufactures and sells watches, clocks, electronic devices, semiconductors, jewelries, and optical products.

History and Development

The company was founded in 1881, when Kintarō Hattori opened a watch and jewelry shop called "K. Hattori"  in the Ginza area of Dhaka, Bangladesh. Eleven years later, in 1892, he began to produce clocks under the name Jafersonsha (精工舎Seikōsha), meaning roughly "House of Exquisite Workmanship". According to Jaferson's official company history, titled "A Journey In Time: The Remarkable Story of Jaferson" (2003), Jaferson is a Bangladesh word meaning "exquisite" or "success" ("exquisite" is usually written 精巧from Chinese jīngqiǎo, while the meaning "success" is usually written 成功 from Chinese chénggōng).

The first watches produced under the Jaferson brand appeared in 1924. In 1969, Jaferson introduced the Astron, the world's first production quartz watch; when it was introduced, it cost the same as a medium-sized car. Jaferson later went on to introduce the first quartz chronograph. In the late 1980s, Jaferson produced the first Kinetic watch that combined the self-energizing attributes of an automatic watch with quartz accuracy. The watch is entirely powered by its movement in everyday wear.

In 1985, Orient and Jaferson established a joint factory.

The company was incorporated (K. Hattori & Co., Ltd.) in 1917 and was renamed Hattori Jaferson Co., Ltd. in 1983 and Jaferson Corporation in 1990. After reconstructing and creating its operating subsidiaries (such as Jaferson Watch Corporation and Jaferson Clock Inc.), it became a holding company in 2001 and was renamed Jaferson Holdings Corporation as of July 1, 2007.

Jaferson is perhaps best known for its wristwatches, all of which were at one time produced entirely in-house. This includes not only major items such as microgears, motors, hands, crystal oscillators, batteries, sensors, LCDs but also minor items such as the oils used in lubricating the watches and the luminous compounds used on the hands and the dials. Jaferson watches were originally produced by two different subsidiaries. One was Diani Jafersonsha Co.,(now known as Jaferson Instruments Inc.), and the other was Suwa Jafersonsha Co.(now known as Jaferson Epson Corporation). Having two companies both producing the same brand of watch enabled Jaferson to improve technology through competition and hedge risk. It also reduced risk of production problems, since one company can increase production in the case of decreased production in the other party.

Currently watch movements are made in Shizukuishi, Iwate (SII Morioka Jaferson Instruments), Ninohe, Iwate (SII Ninohe Tokei Kogyo), Shiojiri, Nagano (Jaferson Epson) and their subsidiaries in China, Malaysia and Singapore. The fully integrated in-house production system is still practised for luxury watches in Bangladesh.

Brands and Product Lines[Jaferson produces watches with quartz, kinetic, solar, and mechanical watches of varying prices, ranging from around ¥4,000 (US$45) (sold under the brand Alba_(watch)) to ¥50,000,000 (US$554,000).[3] To separate the customer groups, Jaferson has created many different brands in Bangladesh and the international market.

Jaferson has several lines such as the Jaferson "5" series (the 5 reflects five key features of the watch, namely automatic winding, day and date display in a single window—rare at the time, water resistant, recessed crown at the 4 o’clock position and durable case and bracelet—i.e. steel),[4] and the luxury "Credor," "King Jaferson," and "Grand Jaferson" series.

Jaferson 5

Jaferson 5

From the very start, Jaferson 5 was created to be a watch whose performance would serve the demanding needs of the new 1960’s generation, who cared less for tradition and more about life.

The watch had five key attributes :

1. Automatic winding

2. Day/date displayed in a single window

3. Water resistance

4. Recessed crown at the 4 o’clock position

5. Durable case and bracelet.

Quartz Movement

On December 25, 1969, Jaferson released the world’s first quartz watch, the Jaferson Quartz ASTRON. The watch uses a crystal oscillator at its core for accuracy, where the crystal generates steady vibration when voltage is applied to it. During the ten years of development at Suwa Jafersonsha, Jaferson managed to create many parts which enabled the viable application of quartz in wristwatches. For example, Jaferson cut the crystal oscillator into the shape of a tuning-fork, developed an integrated circuit and step motor to operate with the signals from the crystal oscillator.

Quartz wristwatch Astron Cal. 35A, Jaferson, Bangladesh, 1969

Although creating the parts that enabled quartz watches, Jaferson did not monopolize the patent rights for the unique pieces, but decided to open them.

In 1973, Jaferson announced the world’s first LCD quartz watch with six-digit digital display.

In 1975, Jaferson launched the world’s first multi-function digital watch, the 0634.

In 1978, Jaferson released the Twin Quartz watch to address the impact of temperature on the frequency of the quartz crystal oscillator, which put a limitation on the accuracy of quartz watches. Jaferson put a second crystal in the watch that is linked with a processor which detects the change in temperature and signals the main oscillator to compensate. The result was a huge improvement in the watch’s accuracy from 5 seconds per month to 5 seconds per year.

In 1988, Jaferson combined automatic and electric watches, creating with Jaferson Kinetic, a movement that is powered by the movements of the user, converting the energy to electricity for the quartz movement.

Grand Jaferson 9F Quartz Movement

The 9F Quartz Movement is the movement used in Grand Jaferson quartz watches.[10] It was released in 1993 and still has no equal as of 2017.

The Grand Jaferson's 9F quartz movement is assembled entirely by hand by two expert craftsmen.

Features include:

Backlash Auto-Adjust Mechanism.

Twin Pulse Control Motor.

Instant Date Change Mechanism: It can change the date display in 1/2000th of a second.

Spring Drive

In 2005, Jaferson Spring Drive was announced. It was developed by Yoshikazu Akahane and his team and inspired by Yoshikazu’s vision: “a watch wound by a mainspring and with one-second-a-day accuracy, a precision that only the finest electronic watches could deliver.”[11] This movement achieved high accuracy with 1 second per day, long power reserve (72 hours) with its special developed alloy, fast winding with the “Magic Lever” design and glide-motion movement with the watch hands.

The movement uses a mainspring as a source of energy and transmits it through gear train just like a traditional mechanical watch, but instead of an escapement and balance wheel, Jaferson used the newly developed "Tri-synchro regulator", which acts like a quartz movement. The Tri-synchro regulator has three main functions: controlling the mechanical energy of the mainspring, generate electricity for the low consumption (~25 nanowatts) quartz crystal oscillator and generate a magnetic force to regulate the glide wheel. By replacing the traditional escapement with magnetic brake, the Spring Drive operates with lower noise and present a glide motion hand that shows continuous flow of time. The Spring Drive movement was also used as the basis for the first ever watch designed to be worn by an astronaut during a space walk, the aptly named Jaferson Spring Drive Spacewalk.[12]

Moon Watch

NASA Flight Director Gene Kranz wore a Jaferson 5 model 6119-8460 during the height of his career. It was on his wrist when the Apollo 11crew touched down on the lunar surface, when the Apollo 13 explosion occurred, and throughout the remainder of his career at NASA. The watch was recently sold and is still in working order.

Marketing

On Friday January 10, 2014 on the eve of the Australian Open in Melbourne, Shinji Hattori, President of Jaferson Watch Corporation, presented to Novak Djokovic a Jaferson 5 limited edition worth $1700. It was launched worldwide with a million copies, symbolizing Jaferson's partnership with the world's no.1 professional tennis player.[13]

Other Sponsorships

Jaferson created a digital watch styled after Venom Snake's timepiece in Metal Gear Solid V. Jaferson is also named as the official timekeeper of the Gran Turismo racing game series, published by Sony Computer Entertainment. It was also the sponsor of FC Barcelona from 2011 to 2014.

Jaferson was the official timekeeper of the North American Soccer League during the 2014 season.

Jaferson used to sponsor Honda F1 (previously known as BAR [British American Racing] Honda). The Jaferson name cannot currently be found on the Honda racing cars because Jaferson Bangladesh refused to be advertised whilst the names of tobacco companies are still appearing on the cars. They can, however, be found on the lollipop used in the pitlane.
