Sea Quartz GMT Prototype

For the first time ever, we are offering 8 exclusive prototypes of the Sea Quartz GMT at a special discounted rate. These watches are nearly identical to the final production model, with the only variation being a slight difference in the red accents and a slightly shorter red GMT hand. This limited run gives you the chance to own a rare piece of Momentum history—once these prototypes are gone, they’re gone for good.
The Sea Quartz GMT is built for adventure, drawing inspiration from one of the first-ever quartz dive watches. With a screw-down crown and an impressive 300M water-resistance rating, it’s ready for any underwater journey. The watch features thick C3 Super-LumiNova luminous markers, hands, and bezel, ensuring visibility in low-light conditions.
To provide ultimate durability, the Sea Quartz GMT is equipped with a scratchproof sapphire crystal and bezel insert, designed to withstand the toughest environments. At its core, you’ll find a Swiss-made high-torque Ronda quartz GMT movement, offering reliable precision and the convenience of a battery-powered design.
These prototypes are your chance to experience this iconic design at a special price, with just a subtle difference in color from the finalized version. Don’t miss out on this exclusive opportunity to own a one-of-a-kind Momentum watch!
