Grand Seiko Sport Automatic GMT SBGM245

A mechanical GMT with a stainless steel bezel SBGM245 is designed to be a go-to for any frequent traveler. The stainless steel case measures 40.5mm in diameter, is rated to 200 meters, and has a magnetic resistance of 4,800 A/m. The bezel is stainless steel and adorned with a 24-hour scale in bold lettering. It is fixed to the case, allowing for the tracking of two time zones. The blue dial has a vibrant sunray finish. The hands and indexes are multi-faceted, beautifully textured, and feature ample LumiBrite paint for excellent nighttime legibility. The red GMT hand can be adjusted without compromising the watch's accuracy. It has a distinctive shape that makes it visible immediately against the dial. SBGM245 runs on caliber 9S66. This is a true GMT movement, which means that the local hour hand is independently adjustable while the GMT hand remains fixed to "home" time. The immediate benefit of this functionality is that upon arriving to a new locale in a different time zone, the owner can simply advance the hour hand forward or backward in one-hour increments to the appropriate time without having to reset the watch. Caliber 9S66 is rated to +5 to -3 seconds per day (when static), has a duration of 72 hours, and features 35 jewels. Like all Grand Seiko mechanical movements, 9S66 is produced by the highly skilled watchmakers of the Shizukuishi Watch Studio.
