Strap for Heritage Black Bay Chronograph Flamingo Blue

The lug width of the Tudor Black Bay Chronograph M79360N-0024 is 22 millimetres. This measurement is determined by the geometry of the 41mm case and represents the internal distance between the two lugs. To verify it, use a digital calliper, measuring perpendicularly between the internal strap attachment points.

The ideal strap depends on your intended use. For elegance and longevity, alligator with vegetable tanning is the most recommended choice: its aesthetic harmonises naturally with the case's satin steel and the leather's thickness guarantees resistance over time. Shell cordovan is the superior technical option for those seeking maximum wear resistance and an impermeable patina. Premium calf leather (Swiss chèvre) offers a good balance between elegance and practicality.

The strap is changed using a dedicated spring bar tool to remove the spring pin that locks the strap to the case lugs. Insert the flat tip of the tool into the pin's groove, gently lift until the pin slides out, then remove the old strap. Proceed in reverse to fit the new strap, ensuring the pin is centred and securely engaged on both sides.

Yes, any 22mm strap is compatible with the M79360N-0024, provided the lug width is exactly 22 millimetres. Milano Straps' bespoke straps are specifically designed for this measurement and guarantee perfect adaptation to the Tudor lugs. It is important to verify that the strap's thickness does not exceed 4-5mm to avoid friction with the spring bar housing.

The lifespan of a leather strap depends on the quality of the material and the intensity of use. High-quality alligator or cordovan with vegetable tanning has an average life of 5-8 years under moderate daily use. Ageing is not a defect: the leather develops a patina that increases aesthetic value. Premium calf leather lasts 3-5 years. Regular maintenance (cleaning and conditioning with natural waxes) significantly extends durability.
