Strap for Tudor Black Bay One 79680

The lug width of the Tudor Black Bay One 79680 is 22 mm. This dimension corresponds to the internal diameter of the lateral tubes of the case where the strap lugs are inserted. It is a standard specification across all examples of this reference, which significantly simplifies the search for compatible straps. Correct measurement refers not to the external diameter of the case, but to the actual distance between the two structural anchorage points.

For the 79680, several options are recommended based on intended use: vegetable-tanned alligator for daily elegance with developing patina; shell cordovan for superior robustness and longevity; grained calf for a balance between maintenance and aesthetic quality; FKM rubber for authentic diving and salt-water resistance; ballistic nylon NATO for versatility and historical military codes. The midnight blue dial pairs particularly well with leather in deep neutral tones such as dark brown, cognac, or grey-tortora.

Changing the strap on the 79680 is a manual operation requiring specific tools: a bifid spring bar tool or a specialised tweezers. Remove the watch from your wrist and work on a flat surface. Insert the bifid tip of the spring bar tool under one of the lateral lug springs of the case, gently lift to create tension, then slide the old strap from the attachment. Repeat for the other side. Insert the new strap by aligning the lugs in the spaces, then lower the springs using the same tool until you hear a click of engagement. Verify that the strap is firmly secured before wearing the watch.

Yes, the Tudor 79680 with its 22 mm lug width is fully compatible with quality aftermarket straps. Leading suppliers offer straps crafted in alligator, shell cordovan, grained calf, FKM rubber, and ballistic fabric, all manufactured to 22 mm specification. Many artisan ateliers also offer bespoke straps customisable in leather selection, colour, width, and stitching details. This compatibility renders the 79680 extremely versatile: you can adapt the strap to the context of use, season, or simply your aesthetic preference without technical constraints.

The durability of a leather strap depends on the material, tanning method, and usage patterns. High-quality vegetable-tanned alligator typically lasts 3–5 years with regular wear, developing a fascinating patina over time. Shell cordovan, thanks to its superior natural density, can exceed 5–7 years whilst maintaining structural integrity. Grained calf has a lifespan comparable to alligator, approximately 3–5 years. Longevity increases if the watch is not worn daily and if the strap undergoes regular maintenance: avoid prolonged contact with water, avoid direct heat sources, and if necessary apply leather-specific conditioners. An FKM rubber strap has potentially superior durability, 7–10 years or more, since it does not degrade from moisture or sun exposure.
