Breguet
Marine 5517BR/12/5ZU— lug 20mm

The lug width of the Breguet Marine 5517BR/12/5ZU is 20mm. This measurement is verified with a digital caliper on the narrowest part of the lug, where the strap connects to the case. This is a specific dimension for this reference and should not be confused with other Marine family models of different diameters.

For the rose gold case of the Marine 5517BR/12/5ZU, polished Alligator crocodile leather is the premier choice in watchmaking: the scale grain enhances the guilloché bezel. Box-calf leather in cognac or burgundy is the most versatile alternative, while vulcanized rubber with a naval texture is ideal for marine use. The buckle or deployant should preferably be in rose gold or champagne PVD.

To replace the strap on a Breguet Marine 5517BR/12/5ZU, you must remove the spring bars that secure the original bracelet to the lugs. This operation requires a dedicated spring bar tool and must be performed carefully to avoid scratching the 18-carat rose gold lugs. It is recommended to entrust this task to a watchmaker or specialized retailer to preserve the integrity of the case.

The lifespan of a leather strap for the Breguet Marine 5517BR/12/5ZU depends on the material, frequency of use, and exposure to sweat and humidity. A quality alligator strap, with proper care, typically lasts 2–4 years of regular use. Box-calf leather has a similar lifespan but develops a characteristic patina. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
