Watch Straps for the Tudor Black Bay GMT
The Tudor Black Bay GMT (M79830RB) is one of the most accessible GMT watches available — a true bi-directional 24-hour bezel GMT at a fraction of the price of the Rolex GMT-Master II. The Black Bay GMT uses a 22mm lug width and ships with three strap options directly from Tudor: a riveted steel bracelet, a tan leather strap, and a navy and red fabric strap. Its vintage-heritage aesthetic and robust 41mm case suit leather, fabric, and rubber equally well. The GMT function and bi-color red-and-blue ('Pepsi') bezel give it an expressive personality that invites strap experimentation. Premium strap alternatives from boutique brands run $70–$130 for 22mm options. AliExpress has leather, fabric, sailcloth, and rubber starting at $5.

What lug width is the Tudor Black Bay GMT?
The Tudor Black Bay GMT M79830RB uses a 22mm lug width. This applies to the current M79830RB-0001 (navy and red Pepsi bezel on fabric strap) and the M79830RB-0002 (on steel bracelet) and all Black Bay GMT references in the current lineup. The 22mm lug is shared with the Tudor Black Bay 41, Black Bay 58, and Black Bay 39, as well as the Seiko SKX007, Seiko Turtle, and many other popular watches — giving the Black Bay GMT access to the widest AliExpress strap selection of any common lug width. The Black Bay GMT's predecessor, the Heritage Black Bay GMT (M79830RB predecessor references), also uses 22mm. Before purchasing, confirm your specific reference on Tudor's website, where lug width is listed under technical specifications.
What's the best cheap leather strap for the Tudor Black Bay GMT?
The best cheap leather strap for the Tudor Black Bay GMT is a heritage-style leather strap in 22mm from AliExpress — a slightly distressed or soft-finish dark brown or tan calfskin that references Tudor's own OEM leather strap. Search 'distressed leather watch strap 22mm' or 'vintage leather strap 22mm quick release' on AliExpress for $8–$18 options. For the most period-correct look, look for straps with a natural taper from 22mm at the lug to 18–20mm at the buckle and a steel or PVD-black deployment clasp rather than a plain buckle. A riveted leather strap with visible stitching or rivet details (search '22mm riveted leather strap') particularly suits the Black Bay GMT's vintage-heritage design and mirrors Tudor's own leather offerings. Tan leather with a navy-thread contrast stitch is a striking pairing for the Pepsi bezel.
Does the Tudor Black Bay GMT look good on a fabric strap?
Yes — the Tudor Black Bay GMT ships from the factory with an optional navy and red striped fabric strap, and it's one of the most popular configurations. Fabric or sailcloth straps in 22mm are natural pairings for the GMT's marine and aviation heritage. Search 'sailcloth strap 22mm quick release' on AliExpress for $8–$18 woven options. For the Pepsi (blue-and-red) Black Bay GMT, a navy or blue-accented sailcloth with red trim echoes the bezel color; a plain navy or grey sailcloth is more understated. Canvas straps in olive or khaki give the Black Bay GMT a field-watch character — unusual but popular among collectors who want to emphasize the tool-watch functionality of the GMT complication. AliExpress woven fabric straps in 22mm are widely available and deliver the woven texture of Tudor's OEM fabric strap at $8–$15.
What's the difference between the Tudor Black Bay and Tudor Black Bay GMT?
The Tudor Black Bay is a standard diver — it has a unidirectional rotating bezel for elapsed dive time and a conventional hours-minutes-seconds display. The Tudor Black Bay GMT has a bi-directional 24-hour bezel calibrated for GMT tracking and an additional GMT hand, allowing the wearer to track a second time zone simultaneously. Both use a 22mm lug width (except the Black Bay 36, which uses 19mm). The Black Bay GMT has a distinctive bi-color 'Pepsi' (blue and red) or 'Coke' (black and red) bezel that makes it visually distinct from the standard Black Bay. Both watches use the same strap dimensions — any 22mm strap fits either watch — so strap guides for the standard Black Bay also apply to the GMT.
