Strap for Black Bay One Only Watch 2015

The Tudor Black Bay 7923-001 features a lug width of 22mm, measured between the pins that connect the case to the strap ends. This is a universal specification: any strap manufactured for 22mm lugs will be compatible with this reference, regardless of material or colour.

For the Black Bay 7923-001, we recommend a vegetable-tanned alligator strap, which maintains aesthetic coherence with the brushed stainless steel case and domed crown. If you prefer a patina that ages gracefully over time, cordovan shell from horsehide is the most noble choice. For a more versatile approach, Italian vegetable-tanned calf in brown or black tones offers aesthetic stability without compromising luxury credentials.

To change the strap, you must remove the two 1.80mm diameter pins that pass through the lugs. Using a spring bar tool, push the small hook of the pin outward to release it from the lug pocket, then extract the strap. Align the new strap holes with the pins and reposition them. The procedure requires care to avoid scratching the case: the Casati Milano atelier offers this professional service if you prefer to delegate.

Yes, if manufactured to standard. All Milano Straps straps for 22mm lug width use pins with standard 1.80mm diameter and are crafted by certified artisan leatherworkers. The key is verifying that the lug pockets have compatible depth (standard 3.2mm) and that the buckle does not interfere with the crown. We always recommend testing the strap before committing to daily wear.

A high-quality leather strap (alligator, cordovan shell or vegetable-tanned calf) has an average lifespan of 3-5 years with daily use, provided correct maintenance is observed. Direct sun exposure accelerates ageing, as does constant humidity if not dried properly. With proper care – monthly cleaning with a damp cloth, semi-annual conditioning with natural oil – the lifespan can extend to 7-8 years. The Casati Milano atelier offers an 18-month guarantee on all straps, with the possibility of restoration.
