ZF Factory Tudor Black Bay GMT Automatic Watch
The ZF Factory Tudor Black Bay GMT combines vintage-inspired styling with practical dual-time functionality. Featuring a 41mm stainless steel case, a red and blue 24-hour bezel, a vintage-style rivet bracelet and a Sea-Gull 2824-based automatic movement, it offers a balanced blend of classic aesthetics and everyday usability.
Designed for travel and daily wear, the GMT function allows a second time zone to be displayed while preserving the recognizable Black Bay design language.
41mm Stainless Steel Case
The watch features a 41mm stainless steel case with an approximate thickness of 11.9mm and a 20mm lug width.
Its relatively slim profile provides a comfortable fit on the wrist while maintaining the sporty proportions of the Black Bay collection. The upper surfaces feature a brushed finish, while polished bevels along the case edges create additional depth and refinement.
Red and Blue 24-Hour Bezel
The classic red and blue bezel is marked with a 24-hour scale and works together with the GMT hand to display a second time zone.
The two-tone color scheme improves day and night distinction while adding one of the most recognizable design elements associated with GMT watches.
GMT Dual Time Zone Function
In addition to displaying hours, minutes and seconds, the watch includes a dedicated GMT hand for tracking a second time zone.
The GMT hand works in conjunction with the fixed 24-hour bezel, making it practical for travelers and users who regularly monitor multiple time zones.
The exact adjustment sequence may vary depending on the movement configuration. It is recommended to verify the GMT, date and local time adjustment functions during QC before shipment.
Vintage-Style Rivet Bracelet
The watch is fitted with a vintage-inspired stainless steel rivet bracelet featuring solid links for improved durability.
Decorative rivet-style side links and a stepped profile recreate the appearance of classic Tudor bracelets while providing a secure and comfortable fit.
The bracelet edges and clasp are smoothly finished for greater comfort during extended daily wear.
Sea-Gull 2824-Based Automatic Movement
The watch is powered by a Sea-Gull 2824-based automatic mechanical movement configured to support the GMT display.
Automatic winding keeps the movement powered during regular wear. Timekeeping performance may vary depending on power reserve, wearing habits, temperature and resting position.
When the watch has not been worn for an extended period, manual winding is recommended before setting the time.
