Strap for Marine Chronograph 5527 White Gold / Blue / Alligator

The lug width of the Breguet Marine 5527BB/Y2/9WV is 20mm. This is the standard size for the Marine family in this 42.3mm diameter and is the specification to reference when purchasing a compatible aftermarket strap.

For the Marine 5527BB/Y2/9WV in white gold, a smooth alligator crocodile strap — ideally in navy blue or black — is the most coherent choice with the case positioning. Box Calf leather is an elegant alternative for daily wear, while vulcanized rubber enhances the sporting vocation of the flyback chronograph.

Strap replacement requires removal of the spring bars housed in the 20mm lugs. Use of a dedicated spring bar tool with a fine tip is recommended to avoid scratches on the white gold case. When in doubt, it is best to consult a watchmaker or the Casati Milano atelier.
