The end of summer
Can a watch mark the changing seasons? Sometimes it almost seems so. The green of the dial and the brown of the strap seem reminiscent of the hues of late summer in the dense forest on the lower slopes of Mount Iwate, the mountain that overlooks the studio where SBGJ239 is made. As autumn comes ever nearer, the shadows lengthen and the light softens and, as it does so, the high legibility of the dial starts to come into its own. Could it be that the watch anticipates the change in the season? Perhaps not but its suitability for all seasons is once again made clear.

Mechanical Hi-Beat 36000 GMT Triple Time
Zone for the next generation
This timepiece achieves unparalleled functionality as the rotating 24-hour bezel—simultaneously displays three different time zones. The design has a profound presence, while still maintaining the traditional shine of a classic Grand Seiko model. Combined with a tough exterior, water resistant down
to 20 bar and highly resistant to shocks, this timepiece has been perfected as the ideal luxurious sports watch for those active on the global stage. The high-quality sapphire glass on the surface of the ring provides a strong sense of transparency, breadth and depth.
The vintage green dial and black/white bezel made of sapphire crystal gives the appearance of a vintage watch.
This model incorporates Caliber 9S86, the high-specification movement that delivers the same accuracy (-5 to +3 seconds a day) and the same power reserve (55 hours) as the core Caliber 9S85, while also offering the GMT function that the international traveler needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed. The red GMT hand shows the time in the home time zone.
