Grand Seiko Automatic GMT Limited Edition ‘Hodinkee’ Ref. SBGM239


Pre-Owned Grand Seiko 39mm Automatic GMT Limited Edition ‘Hodinkee’ Blue Dial, Stainless Steel Bracelet, Ref. SBGM239

A three year collaboration between Grand Seiko and Hodinkee brings this unique timepiece, the ‘Hodinkee’ Automatic GMT. This limited edition GMT is one of just 500 produced, and the Japanese company flashes their commitment to high level quality with no compromises. The dial, resting inside a stainless steel case, features what Hodinkee calls ‘twilight blue’, which is meant to represent the transition from day to night. Powering this GMT and on display thanks to the exhibition display, is a self winding 9S66 caliber movement, designed in house by Grand Seiko, and offering 72 hours of power reserve. And most importantly, its integrated GMT complication is incredibly easy to use. The local hour hand can be adjusted in one-hour increments, either forward or backward, in the crown’s first position. The GMT hand is connected to the minute hand, so you should adjust your second time-zone first and then jump the primary hour hand to match your local time. We also have a day reference at the 3 hour in addition to a dedicated GMT hand. Attached is a comfortable stainless steel bracelet geared to offer both a causal yet sporty vibe to Hodinkees Automatic GMT. This Automatic GMT for Hodinkee comes complete with original box and papers.

The first Grand Seiko was released in 1960 as the result of a team effort that was challenged to build a watch that would be as precise, durable, easy to wear and beautiful as humanly possible.  The first Grand Seiko was a major advance. The new caliber 3180 was accurate to within +12 to -3 seconds a day and offered a power reserve of 45 hours. It was the first watch in Japan to be compliant with the standard of excellence of the Bureaux Officiels de Contrôle de la Marche des Montres.  Just four years after the creation of the first Grand Seiko, the Grand Seiko Self-Dater was introduced. The emphasis was on practicality included an additional calendar function and improved water resistance up to 50 meters.

Released in 1967, 44GS had the highest level of accuracy of any manually wound 5 beat watch in the world. In just a few short years, Grand Seiko had made extraordinary strides towards its goal. The design of 44GS included many aspects that have been passed on to today’s Grand Seiko watches.  44GS established the look that Grand Seiko has continued to this day. It was a complex design idea, with rules about proportion, finish, angles and every other design aspect. Indeed, there were three basic principles and no fewer than nine elements required to achieve them. No other watch has had such an influence on the character of Grand Seiko.

Development continued at a rapid pace with the release in 1967 of the 62GS, the first automatic Grand Seiko, followed in 1968, by the automatic 10 beat 61GS and the manual 10 beat 45GS.  In 1968, a Seiko movement was awarded the overall prize as the best mechanical watches in the Geneva observatory competition and the world saw that the Grand Seiko movements were among the very best in the world.

In 1988, the first Grand Seiko quartz watch, the 95GS was born. It far exceeded the performance of all regular quartz watches with its accuracy of ±10 seconds per year. Using quartz crystals grown in its own facilities and in its own way, the Grand Seiko team was able to select only those oscillators that exhibited superior performance in temperature resistance, humidity resistance and shock resistance, to produce movements with the highest possible accuracy.

While the first Grand Seiko quartz watch was exceptional, it did not quench the enthusiasm of the Grand Seiko team to go further and create the ‘ideal’ quartz watch. In 1993, just five years after the arrival of the first Grand Seiko quartz watch, Caliber 9F83 was completed. This quartz watch incorporated four key innovations, the Backlash Auto-Adjust Mechanism, the Twin Pulse Control System, the Instant Date Change Mechanism, and the protective shield construction. It sought to embody what Grand Seiko considered to be the essential qualities of a wrist watch, namely: accuracy, beauty, legibility, durability and ease of use.  Grand Seiko watches continue to strive to achieve these qualities.
