🔎 Case Notes

*** NOTE The Discoloration in the pictures is from the protective stickers applied at the factory ***

The Tudor Black Bay GMT “Coke” Ref. M79830RB is one of the most compelling modern travel watches on the market — blending vintage-inspired aesthetics with contemporary capability in a way only Tudor seems to manage so effortlessly.

Distinguished by its black and red aluminum bezel, the “Coke” configuration offers a slightly warmer, more understated alternative to the blue-and-red “Pepsi.” The contrast is sharp but controlled, giving the watch a tool-forward presence that feels purposeful rather than flashy.

At 41mm, the case wears with confidence while maintaining excellent balance on the wrist. This particular example is offered new in box, unworn, and mostly stickered, presenting as close to factory-fresh as one could reasonably hope to find. It includes the full original kit, making it a standout opportunity for collectors seeking condition and completeness without compromise.
