Strap for Marine Dame 9517 Stainless Steel / MOP / Alligator

The Breguet Marine 9517ST/5W/984 is fitted with a 20mm lug width. This measurement is taken with a digital caliper positioned between the two case lugs at the attachment point with the strap. The strap tail is typically 16mm or 18mm to ensure a harmonious fit with the buckle.

For the Marine 9517ST/5W/984 with steel case and white dial, an alligator Mississippiensis strap with hornback grain in midnight blue or slate gray is the choice most consistent with the watch's haute horlogerie positioning. Alternatively, an impermeably finished calf leather with fine grain or vulcanized rubber with embossed texture are ideal for daily or marine use, maintaining proper proportions on the 20mm lug width.

Strap replacement on the Breguet Marine 9517ST/5W/984 is done via standard 20mm spring bars, accessible with a dedicated lever tool or a flat-head screwdriver with a protected tip. It is recommended to work on a soft surface to protect the case and sapphire crystal. If uncertain, Casati Milano offers mounting service at their atelier by appointment.

Yes. Any strap with a 20mm attachment and standard spring bars is compatible with the Breguet Marine 9517ST/5W/984. Milano Straps offers a selection of artisanal 20mm straps—in alligator, calf, NATO, and rubber—designed to fit perfectly with the case geometry and its nautique aesthetic.

The lifespan of a leather strap depends on the quality of the leather, frequency of use, and exposure to perspiration and humidity. A high-quality alligator strap, with proper care using suitable products, typically lasts 2 to 4 years with daily use. Casati Milano straps are covered by an 18-month warranty against manufacturing defects and are made with carefully selected leather that guarantees color stability and structural integrity over time.
