Strap for Marine Chronograph 5529 White Gold - Diamond / Blue / Alligator

The Breguet Marine 5529BB/YD/9WV/D0 is fitted with a 20mm lug width. This is the standard size for all 42mm Marine models of this generation. To verify, measure with a caliper between the two case lugs at the spring bar attachment point.

For the 5529BB/YD/9WV/D0 in white gold, smooth alligator in midnight blue or slate gray offers the best formal balance. For daily wear, boxcalf develops a distinguished patina over time. For marine or sports use, vulcanized rubber aligns best with the Marine's nautical identity.

The strap is removed using a spring bar tool with a lever or fork, which acts on the spring bars inserted into the 20mm lugs. This requires care to avoid scratching the white gold case. It is recommended to have the change performed by a watchmaker or at Casati Milano, where this service is included with strap purchase.

Yes, any 20mm strap with compatible lug geometry fits the Marine 5529. A selection of artisanal 20mm straps—alligator, calf, NATO, and rubber—is available on milanostraps.it, designed for precise fitting on curved case profiles like the Marine.

An artisanal quality alligator or calf strap lasts an average of 2 to 4 years with regular use, depending on exposure to humidity, perspiration, and direct sunlight. Avoiding contact with salt water significantly extends leather life. Casati Milano offers an 18-month warranty against manufacturing defects on all straps crafted in their atelier.
