Strap for Marine 5517 Titanium / Blue / Rubber

The lug width of the Breguet Marine 5517TI/Y1/5ZU is 20mm at the case attachment point. This measurement is taken with a digital caliper positioned between the two lugs, internally at the case, at the narrowest point. This is the standard measurement that determines compatibility with any aftermarket 20mm strap.

For the titanium Marine 5517TI/Y1/5ZU, the most suitable materials are hornback alligator in midnight blue or slate gray — consistent with the model's nautical DNA — and box-grain calf for urban settings. For sports or marine use, a vulcanized rubber strap with a titanium deployant clasp is the most functional technical solution. Nylon NATO recalls the military-marine aesthetics of its origins.

To replace the strap on the Marine 5517TI/Y1/5ZU, you must remove the springbars measuring 1.8mm in diameter and 20mm in length housed in the lugs. Use a dedicated springbar tool with a fine tip to avoid scratching the titanium case. The operation takes just a few minutes; if in doubt, it is advisable to consult a watchmaker or the Casati Milano atelier.

Yes. Any aftermarket strap with a 20mm lug width and straight or slightly curved case end is compatible with the Breguet Marine 5517TI/Y1/5ZU. On milanostraps.it you will find a selection of 20mm straps in alligator, calf, rubber, and NATO, with the possibility of custom creation through the Casati Milano atelier for a precise tailored result.

The lifespan of a leather strap depends on the material, use, and maintenance. A quality alligator strap, with regular care using nourishing cream and protection from moisture, lasts an average of 4-5 years. Box-grain calf has an average life of 2-3 years with daily use. For marine or sports environments, vulcanized rubber straps are recommended, as they resist water, sweat, and UV rays without accelerated deterioration.
