Strap for Marine Hora Mundi 5557 White Gold / Blue / Alligator

The Breguet Marine 5557BB/YS/9WV has a lug width of 20mm. This is a standard size that allows for a good selection of aftermarket straps, but it is essential to verify that the top end of the strap has a curved end profile compatible with the characteristic curvature of the lugs on this white gold model.

For the Marine 5557BB/YS/9WV in white gold, alligator leather in a polished deep blue or navy finish represents the most coherent choice with the marine vocation of the piece and the preciousness of the metal. Alternatively, a black box calf offers formal rigor, while vulcanized rubber emphasizes the model's tool-watch origins with a deliberate textural contrast between matte rubber and a polished case.

To replace the strap on the Breguet Marine 5557BB/YS/9WV, you must remove the spring bars using a dedicated forked-tip tool, taking care not to scratch the white gold case. Given the curvature of the lugs, it is recommended to entrust the operation to an experienced watchmaker or to the Casati Milano atelier, where the installation is performed with professional tools without risk of damaging the metal surface.

Yes, there are high-quality aftermarket straps compatible with the Breguet Marine 5557BB/YS/9WV. The critical parameter is the 20mm lug width and the presence of a curved end with the correct radius to fit the curvature of the case lugs. On milanostraps.it, a selection of 20mm artisanal straps is available, with the possibility of bespoke customization at the Casati Milano atelier for a tailored fit.

The lifespan of a leather strap depends on the material, care, and frequency of use. A quality alligator strap, properly treated and kept away from water and prolonged perspiration, maintains structural and aesthetic integrity for 2-4 years of regular use. Box calf, more resistant to moisture, develops a patina over time that enhances its character. Casati Milano offers an 18-month warranty against manufacturing defects on all artisanal straps.
