Stainless steel

The Black Bay 58 GMT at 38mm is a genuinely uncommon proposition in the current GMT market — a complication traditionally housed in 40mm-plus cases, here reduced to a proportion that wears considerably closer to a dress watch. For the collector who finds the standard GMT case too large for daily wear, the BB58 GMT is one of very few current-production alternatives that does not compromise on movement quality or legibility
The MT5402 is COSC-certified and running at +1 second per day — comfortably within the chronometer specification of -4/+6 seconds per day. With a 70-hour power reserve and bidirectional GMT functionality, this is Tudor's most capable in-house movement, competing directly with calibres at a significantly higher price point
The 'Coke' bezel — red and black aluminium — evokes a bezel palette with genuine heritage. This 2026 example with full box and papers offers immediate availability at a meaningful saving over new authorised dealer pricing

Minor hairline scratches on case and bracelet
Minor scuff on bracelet clasp, can be polished on request
