Strap for Tudor Black Bay 79250BM

The lug width of the Tudor Black Bay 79250BM is 23mm, measured between the two lugs (pins) that attach the strap to the case. This is the standard size for the 43mm model and is compatible with a vast range of artisanal straps.

The Black Bay 79250BM pairs beautifully with alligator, aged calf leather, vegetable-tanned shell cordovan, and vulcanised rubber straps. To enhance the bronze, we recommend dark brown calf with amber-toned stitching, or alligator in greenish hues that echo the mature patina of the metal.

It's straightforward: use a spring bar tool or pin remover. Position the tool under the pin on the opposite side of the pressure point and gently push to extract it. Once removed, slide off the old strap and insert the new one, keeping the pins aligned with the lugs, then reinsert the pins.

Yes, any 23mm strap is compatible with the 79250BM. However, we recommend quality artisanal straps that respect the thickness and structure required by such a tool watch. A good aftermarket leather strap ages alongside the bronze, creating superior aesthetic harmony.

Durability depends on usage, material, and care. Quality vegetable-tanned calf typically lasts 3-5 years with daily wear, whilst alligator or cordovan can last 5-7 years. Exposure to salt water (frequent on a submariner) accelerates ageing. With regular maintenance—cleaning and conditioning—longevity increases significantly.
