WHAT WE LOVE:

The Tudor Black Bay GMT has established itself as one of the most convincing sport GMT watches in its price category — and the opaline dial variant is the configuration that best demonstrates the range's breadth of appeal. Where the black dial Black Bay GMT reads as a tool watch that happens to look good, the opaline version reads as something more versatile: a watch that carries the same credentials but wears them with considerably more elegance.

Tudor describes the dial as silvery, with a slight warmth that shifts depending on the light. Produced through a galvanic process, the matte finish has depth rather than brilliance, and the darkened surrounds on the applied markers create a contrast that gives the dial visual structure without relying on the stark black-on-white formula. Against the matte burgundy and blue "Pepsi" bezel the combination is immediately recognisable as Black Bay GMT while feeling entirely different from the standard black dial variant. The Snowflake hands — Tudor's signature, carried from the vintage era — carry their Super-LumiNova fill effectively across both the silvery dial surface and in darkness, and the independently jumping GMT hand completes a dial that is genuinely pleasure to read.

The 41mm case maintains the Black Bay GMT's defining feature: full 200-metre water resistance, a specification shared with Tudor's dedicated diver references and made possible by the screw-down Tudor rose crown and the overall Oyster-derived case architecture. The riveted three-link steel bracelet with its polished and satin alternating finish is one of the more characterful bracelets in the sport watch category, referencing the original metal bracelets of vintage Tudor references while wearing comfortably on a modern wrist. This example comes complete with its box and papers along with Tudor warranty from 2025.

WHAT'S INSIDE:

The 79830RB is powered by Tudor's Manufacture Calibre MT5652 — an in-house automatic movement that holds both COSC chronometer and METAS Master Chronometer certifications. Beating at 28,800 vibrations per hour across 28 jewels with a bidirectional winding rotor, it delivers a power reserve of 70 hours.
