Tudor Black Bay GMT - Opaline Dial, Fabric Strap, Unworn, Ref. M79830RB-0012 (2025)

Tudor introduced the Black Bay GMT in 2018, its first watch to combine the Black Bay dive-watch silhouette with a GMT complication and an in-house automatic movement. The red-and-blue bezel is a deliberate nod to the two-tone GMT bezels first popularised on tool watches in the 1950s and 60s, giving the Black Bay GMT an unmistakable, sporty presence on the wrist.

This 2025 example is finished with an opaline dial, a warmer, slightly textured white finish that contrasts with the more common black dial versions, and is presented on a fabric strap rather than the brand's steel bracelet, giving it a more casual, everyday character.

As an unworn piece, this watch comes without any wear history, offering the chance to own a current-production Tudor GMT in pristine, as-new condition, reference M79830RB-0012.

As with every Watchlunex listing, this piece ships fully insured and is backed by our 30-day return policy, so you have time to confirm fit and feel before deciding to keep it.
