Strap for Tudor Black Bay 79220B

The lug width of the Tudor Black Bay 79220B is 22mm. This dimension is specific to the 41mm case of this model and corresponds to the internal space between the pins that attach the strap. Any aftermarket strap must present exactly 22mm in width to ensure correct fit and security.

The most compatible strap depends on usage: alligator in black represents the classic choice for formal and diving contexts, while vegetable-tanned calfskin offers daily versatility. Shell cordovan introduces burgundy tones that elegantly contrast with the blue dial. For intensive and aquatic use, a cotton NATO or vulcanised rubber ensures maximum resistance and practicality.

Changing the strap on the 79220B requires a spring bar tool. Position the tool in the two lateral notches of the spring, apply gentle and simultaneous pressure on both sides to deactivate the hooks, then remove the pin and previous strap. Insert the new strap, return the pin to position and verify that it is secured symmetrically on both lugs.

Yes, provided the aftermarket strap has a lug width of 22mm. Numerous manufacturers offer straps in alligator, calfskin, cordovan and rubber with this dimension. Verify that the strap thickness does not exceed 3.5-4mm, so as not to obstruct the bezel rotation and ensure comfort when wearing.

A quality leather strap (alligator, calfskin, cordovan) on a Tudor Black Bay 79220B lasts an average of 3–5 years with daily wear, depending on frequency of use, humidity exposure and care. Vegetable-tanned leather ages better, developing patina; vulcanised rubber reaches 7–10 years. Regular maintenance (drying after perspiration, treatment with natural wax every 6 months) significantly extends durability.
