Octanis Sigma GMT 42 - Founders Edition - Nautical Twilight

Where the stars meet the sea: A deep blue dial captures the open water, while the orange horizon line provides the perfect fix for the celestial traveler.
When you're transitioning through time zones, you need gear that adapts instantly. We engineered this watch around the Miyota 9075 True GMT movement. Purpose-built for the frequent flyer, it gives you an independent local hour hand that clicks seamlessly into place as you land, leaving your home time completely undisturbed.
To maximize utility without adding external bulk or weak points, we integrated an internal 24-hour bezel. Protected safely beneath the scratch-resistant crystal and controlled via an internal geared crown, it allows you to calculate a third time zone instantaneously. No accidental knocks, no chipped bezel inserts—just pure, reliable tool-watch utility.
Included with each piece are:
- 3-watch travel roll
- Extra FKM rubber strap (color matched to the orange on the internal bezel
- Warranty card
- Octanis sticker
The stainless-steel bracelet's buckle features a quick adjust feature for quick adjustments as your wrist shrinks and swells throughout the day!
