Strap for Tudor Black Bay One 79503

The Tudor Black Bay One 79503 features a 19mm lug width with a lug hole depth of 10.5mm. This measurement is specific to this model and requires dedicated watch straps to ensure a perfect fit on the case.

For the 79503, we recommend an alligator strap in navy blue or black for an elegant look, or vegetable-tanned calf leather for a more rustic aesthetic. Choice depends on usage: for sports wear, a NATO or FKM rubber strap are functional options. A deployante buckle ensures ease of wear.

To change the strap, position the watch on a soft surface. Use a spring bar tool to gently extract the pins from the case lugs. Align the new strap holes with the lugs and carefully reinsert the pins. Verify that the strap is firmly secured before wearing the watch.

No, the 19mm strap is specific to watches with this lug width. It is not compatible with models using 20mm, 21mm, or other lug widths. Always verify the lug width of your watch before purchasing a strap.

A premium leather strap (alligator, calf, shell cordovan) with moderate wear typically lasts 3-5 years. Longevity depends on wearing frequency, climate conditions, and maintenance. NATO or rubber straps have greater durability, often lasting 5-10 years.
