Strap for Marine 5517 White Gold / Blue / Bracelet

The lug width of the Breguet Marine 5517BB/Y2/BZ0 is 20mm. To verify, insert a spring bar between the lugs and measure the net distance—the correct value is 20mm. Note: this model may require straps with curved ends to ensure a smooth transition between case and strap.

For the white gold Marine 5517BB/Y2/BZ0, night blue or slate alligator belly represents the most coherent choice with the model's identity: the natural texture of the reptile leather responds to the dial's guilloché, and the cool tone of the color complements the white metal alloy. Navy or burgundy box calf is the more formal dress alternative.

Replacing the integrated bracelet of the Breguet Marine 5517BB/Y2/BZ0 requires a flathead knife or a dedicated bracelet removal tool to remove the spring bar from the lugs. It is recommended to entrust the work to a watchmaker or specialized atelier to avoid scratches on the white gold case. Casati Milano atelier offers mounting service by appointment.

Yes, quality aftermarket straps compatible with the Breguet Marine 5517BB/Y2/BZ0 are available, provided they respect the 20mm lug width and, where necessary, feature curved ends to fit the case geometry. A selection of 20mm straps in alligator, calf, NATO, and vulcanized rubber suitable for this model is available at milanostraps.it.

The lifespan of a leather strap depends on material quality, frequency of use, and exposure to sweat and humidity. A high-quality alligator or calf strap, with regular but not intensive use, has an average lifespan of 2-4 years. Casati Milano straps are covered by an 18-month warranty against manufacturing defects and can be treated periodically with specific products to extend their life.
