GMT MOD

The GMT Mod is the watch for anyone who needs to track more than one time zone—or simply wants to. Drawing on the great GMT classics of the 1960s, originally developed for pilots and long-haul travellers, the GMT Mod carries a dedicated 24-hour hand for the second time zone alongside a bi-directional rotating bezel for quick reference. This is not a decorator; it is a genuine dual-timezone tool watch built on a Seiko automatic platform.

The GMT Movement: Seiko NH34

What sets the GMT Mod apart from most modded watches in this price range is the movement inside: the Seiko NH34 automatic, a true GMT caliber with an independently adjustable 24-hour hand. Home time stays on the 24h hand; local time is set via the standard hour hand—adjusted in one-hour jumps without disturbing the minute display. Exactly how a GMT should work. Hacking seconds and hand-winding are both included; power reserve is approximately 41 hours.

Bezel Variants

The collection covers the classic GMT color combinations that enthusiasts immediately recognize: Pepsi (red/blue), Batman and Batgirl (black/blue), Coke (red/black), Root Beer (brown/gold), Sprite (green/black), plus single-color and two-tone options. Each colorway has its own personality and its own history in the GMT world.
