Strap for Fifty Fathoms Titanium / Blue / Sailcloth

The lug width is 23mm. This dimension is specific to the contemporary Fifty Fathoms collection and ensures balanced proportions on the 45mm case. To verify, remove the original strap and measure the internal space between the case lugs.

Hand-stitched alligator with natural tanning represents the sports luxury standard. For pure diving vocations, we recommend vulcanised rubber in black or navy. Vegetable-tanned calf leather introduces authentic patina. Shell cordovan in grey-sand tones enhances the titanium with modern elegance.

Replacement is performed by removing the pins that fasten the strap to the case lugs. This operation is always best entrusted to a professional watchmaker. Once the old strap is removed, the new one (23mm lug width) is inserted by aligning the holes and repositioning the pins until the safety click is heard.

Yes. Any bespoke strap crafted for 23mm lug width fits the Fifty Fathoms 5015-12B40-O52A without lateral play or forcing. Milan Straps offers a complete selection of materials (alligator, calf, rubber, shell cordovan) in strict tolerances for this watch.

A premium leather strap (alligator, vegetable-tanned calf) lasts 3–7 years depending on use and care. Vegetable tanning develops natural patina, improving aesthetics over time. Casati Milano provides an 18-month warranty against manufacturing defects on all hand-crafted straps.
