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

The lug width of the Breguet Marine 5557BR/YS/5WV is 20mm. This dimension is measured with a digital caliper directly between the two lugs of the case, at the spring bar attachment point. It is important not to measure on the original integrated bracelet, but on the case itself.

For the Marine 5557 in rose gold, the hornback alligator strap in cognac or bordeaux tones is the most coherent choice: the scales dialogue with the guilloché dial and the warm tones enhance the metal. Alternatively, a brown Box Calf leather with a rose gold buckle or an FKM rubber strap for marine use are technically motivated and aesthetically precise choices.

Strap replacement requires removal of the spring bars that connect the original bracelet to the case lugs. It is advisable to entrust this to a watchmaker or use a dedicated flat-tip screwdriver with protection to avoid scratching the rose gold case. The lugs of the 5557 have a curved profile, so it is preferable to use straps with shaped or custom-made ends.

Yes, there are aftermarket straps compatible with standard 20mm attachment that fit the Breguet Marine 5557BR/YS/5WV. On milanostraps.it you will find a selection of 20mm straps in various materials — alligator, leather, rubber and NATO — designed to guarantee dimensional compatibility and artisanal quality appropriate for a watch in this range. For optimal fit, Casati Milano also creates custom straps with shaped ends to follow the lug profile.

The lifespan of a leather strap depends on the material, care and frequency of use. High-quality alligator, kept away from excessive water and humidity, can last from 3 to 5 years with regular use. Box Calf leather develops a characteristic patina over time but is more sensitive to perspiration. Casati Milano straps are covered by an 18-month warranty against manufacturing defects and are made with leathers selected from certified tanneries to ensure maximum longevity.
