Description

The rich green color of the dial and ceramic bezel, inspired by the color of over 2000 different moss varieties that grow in Japan, is the first thing that will catch your eye when looking at the Grand Seiko Sport Collection GMT Spring Drive SBGE 257. But it is the innovative 9R66 Spring Drive movement that makes this timepiece truly special. The Spring Drive movement utilizes both a mechanical movement, as well as an electronic regulator that allows for a higher level of precision than a mechanical-only movement. The movement of the second hand on the SBGE 257 glides around the dial, versus the rapid beat of the second hand on a mechanical movement timepiece, or the one-second tick of one on a quartz watch.

The History:

In 1960, a specialized group of craftsmen set out to design and create an in-house movement for Seiko, which resulted in the Calibre 3180. This movement became the foundation for a new line of Seiko timepieces that would become the Grand Seiko. The pursuit was to create the “ideal watch” in every way, from precision, legibility, and beauty. Having conquered the movement, the designers next set out to create a case and finish that modeled their idea of beauty, which included the use of zaratsu polishing. This polishing process creates a mirror-like quality to the case finish, as well as the hands and indices, that give the Grand Seiko its distinct appearance.

The Watch:

The Grand Seiko Sport Collection GMT Spring Drive SBGE 257 has a 40.5mm stainless steel case with a green ceramic bezel. This timepiece features a domed sapphire crystal with AR-coating on the interior. Powered by the Spring Drive Calibre 9R66 movement, the SBGE 257 has a 72-hour power reserve and a water resistance rating of 200 meters. The green dial features zaratsu-polished indices, hour, minute, and seconds hands, a yellow GMT hand, as well as a date window at the 4 o’clock position.

The Details:

This Grand Seiko Sport Collection GMT Spring Drive SBGE 257 is in excellent condition. Purchased new from an AD in August 2021, this timepiece shows very little wear, as visible in the photographs. Included with this watch are the outer and inner boxes, warranty booklet, operating manual, serial number hang tag, as well as a Grand Seiko polishing cloth. This timepiece comes fitted with the Grand Seiko stainless steel bracelet with a three-fold clasp and push-button release.
