What to know
Where the GG-13 and GG-14 experiment with crystallised metal on the dial, the Genesis GG-15 makes the exterior itself part of the story. Gruppo Gamma ages the stainless-steel case to evoke years of use, then pairs it with a deep tropical-brown sandwich dial, luminous markers and striking blued-steel hands. The result feels informed by the history of practical diving and military instruments.
The square-cushion case measures 44 mm across and 53 mm lug to lug, with its box-shaped anti-reflective sapphire crystal bringing total thickness to 15.5 mm. It uses a screw-down crown and solid caseback to achieve a quoted water-resistance rating of 200 metres. Despite the deliberately weathered appearance, the mechanical construction is contemporary.

A Sellita SW200-1 automatic movement drives hours, minutes and central seconds with a 41-hour power reserve. Listed at $890, the GG-15 is already publicly shown, while a temporary manufacturer notice indicates that orders received through October 31 will ship after November 1. This is a forthcoming distribution update rather than an unrevealed launch.
