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

The lug width of the Breguet Marine 5557BB/YS/5WV is 20mm. This is the measurement to verify between the two lugs of the case before purchasing an aftermarket strap. It is recommended to measure it with a digital caliper at the narrowest point of the lug to obtain the exact measurement.

For a white gold case like the 5557BB/YS/5WV, a polished midnight blue or black alligator strap is the most fitting pairing with Haute Horlogerie. Smooth box-calf leather is an elegant and understated alternative, while quality artisanal vulcanized rubber respects the Marine's nautical vocation without compromising the metal's prestige.

The Breguet Marine 5557BB/YS/5WV is fitted with standard 20mm spring bars. Replacement requires a dedicated spring bar tool with a fine point, preferably with a forked head to avoid scratching the white gold lugs. It is recommended to work on a soft surface and, if in doubt, to consult a watchmaker or the Casati Milano atelier.

Yes. Aftermarket straps with straight 20mm attachment are compatible with the Breguet Marine 5557BB/YS/5WV. It is important to choose models with slightly tapered or straight ends, consistent with the geometry of the Breguet lugs. Milano Straps offers a selection of artisanal 20mm straps compatible with this model, available online or customizable at the Casati Milano atelier.

The lifespan of a leather strap depends on the material and daily use. A quality artisanal alligator or calf leather strap, with regular maintenance and rotation with other straps, has an average life of 2-4 years. The 18-month warranty against manufacturing defects offered by Casati Milano protects your investment, while a natural patina that develops over time is a sign of genuine quality leather.
