Watch description
The Black Bay GMT is an extension of the Black Bay line with a highly functional complication: a multiple time-zone function – also known as a GMT function. Recognizable by its rotatable bezel, which derives its deep blue and burgundy colour theme from other models in the Black Bay line, but in a matt version, the Black Bay GMT is also a nod to the early days of this watchmaking function.
Featuring a 41mm steel case and a bidirectional burgundy-blue bezel, the Black Bay GMT offers robust style and dual time zone functionality.

Five-year transferable guarantee with no registration or periodic maintenance checks required
Autonomy
Power reserve of approximately 70 hours

The Black Bay remains one of TUDOR’s most recognized and recognizable models. Featuring dials inspired by the TUDOR divers’ watches produced during the 1950s, it borrows the characteristic angular hands known to collectors as “Snowflake” from models that appeared in the brand’s 1969 catalogue. Its shoulderless crown and the characteristics of its case are reminiscent of the first generations of TUDOR divers’ watches.
The Black Bay line is the result of the subtle blend of traditional aesthetics and contemporary watchmaking. Far from simply being an identical re-release of a classic, it brings together 70 years of TUDOR dive watches, whilst at the same time being resolutely anchored in the present. It is neo-vintage in conception, yet its manufacturing techniques, reliability, robustness and the quality of its finishes are consistent with today’s more rigorous requirements.
