Breguet
Marine 9517ST/E2/584— lug 20mm

The Breguet Marine 9517ST/E2/584 is fitted with a 20mm lug width. This measurement is taken with a digital caliper positioned between the lugs at the case, at the innermost point, parallel to the bezel. This is the correct measurement to provide when ordering a compatible aftermarket strap.

For the stainless steel Marine 9517ST/E2/584, the most suitable straps are smooth alligator in ocean blue or black—consistent with Breguet's haute horlogerie aesthetic—and box-calf leather for everyday wear. Rubber is the ideal choice for marine or sports contexts, while nylon NATO straps echo the Marine collection's naval heritage.

To replace the bracelet or strap on the Breguet Marine 9517ST/E2/584, you need a proper springbar tool, preferably with a fine tip to avoid scratching the stainless steel lugs. Remove the spring bars securing the bracelet to the case and insert the new 20mm strap. It is recommended to entrust this to an experienced watchmaker or specialized atelier such as Casati Milano to preserve the integrity of the case.

Yes. The Breguet Marine 9517ST/E2/584 accepts standard 20mm aftermarket straps, available in alligator, calf leather, NATO, rubber, and other materials. At milanostraps.it you will find a selection of compatible 20mm straps, with the possibility of artisanal customization through the Casati Milano atelier.

The durability of a leather strap depends on the quality of the leather, frequency of use, and exposure to sweat and humidity. A high-quality artisanal alligator or calf strap, with proper maintenance and rotation with other straps, can last 2 to 5 years while maintaining good structural integrity. Casati Milano offers an 18-month warranty against manufacturing defects on all straps produced in the atelier.
