Strap for Heritage Black Bay Bronze / Bucherer Blue / Fabric

The lug width of the Tudor Black Bay 79250BB-0001 is 23mm. This unconventional measurement requires particular attention when searching for aftermarket straps, as most standard manufacturers offer only 20mm or 24mm widths. To verify compatibility, measure the internal space between the lugs using a digital calliper.

The best strap depends on intended use and personal preference. For elegance and visual coherence with the bronze, an alligator strap in vegetable tanning with a warm brown tone is ideal; it evolves naturally alongside the bronze patina. Alternatively, black shell cordovan guarantees exceptional durability and moisture resistance. For sporting practicality, a technical grey rubber strap offers chromatic versatility without compromise.

Remove the watch from your wrist and use a spring bar tool (a bifid-tipped instrument) to compress the elastic pins. Insert the tip under the pin from one lug, compress slightly and extract; repeat from the other side. Position the pins in the new strap, aligning the eyelets, and compress until the pin locks inside the case. Verify that the strap is securely fastened before wearing the watch.

All straps with a 23mm lug width are compatible with the 79250BB-0001. Milano Straps offers an extensive selection of 23mm models: alligator, vintage calf in vegetable tanning, shell cordovan, technical rubber. The important point is that the strap is specifically labelled as 23mm to ensure a perfect fit to the case pins.

Durability depends on the material and usage. An alligator or vintage calf strap, in vegetable tanning, used daily, maintains solid functionality for 3–4 years before possibly requiring replacement. Shell cordovan, thanks to superior molecular density, reaches 4–6 years of intensive use. Technical rubber straps last 2–3 years under normal conditions. The Casati Milano atelier provides an 18-month warranty on all custom-made straps.
