Breguet
Marine 5577BR/G2/5WV— lug 20mm

The Breguet Marine 5577BR/G2/5WV is fitted with a 20mm lug width. This measurement should be taken with a caliper between the inner walls of the two lugs at the strap attachment point to ensure precise replacement without forcing on the rose gold case.

For the Marine 5577 in rose gold, smooth alligator in bordeaux or cognac represents the most coherent choice with the haute horlogerie character of the tourbillon. Grained calf and vulcanized rubber in navy are excellent alternatives for more sporty or daily use, respecting the proportions of the integrated 20mm lugs.

Replacing the strap on the Marine 5577 requires a 20mm spring bar and a dedicated screwdriver or soft-tipped lever tool to avoid scratching the rose gold lugs. It is recommended to entrust the task to a watchmaker or contact Casati Milano for workshop mounting, where every operation is performed with protective covers on the case.

Yes, Milano Straps offers a selection of 20mm aftermarket straps compatible with the Breguet Marine 5577BR/G2/5WV, handcrafted in alligator, calf, NATO, and rubber. Each strap is produced with spring bars included and a buckle calibrated for 20mm sizing, for direct installation without modifications.

The lifespan of a leather strap depends on use and maintenance: under normal conditions, a high-quality alligator or calf strap has a useful life of 18-36 months. Casati Milano guarantees its straps for 18 months against manufacturing defects. To extend strap life, it is advisable to avoid prolonged contact with water and sweat, alternating use with a second strap.
