Strap for Type XX Stainless Steel / Black / Alligator

The Breguet Type XX 3800ST/92/9W6 is fitted with 20mm lugs. This measurement is taken with a caliper positioned between the two lugs at the strap attachment point, and is compatible with standard 20mm aftermarket strap options.

It depends on intended use. For formal occasions, polished alligator in black or brown complements the stainless steel case finishing. For daily wear, smooth calfskin in cognac or tobacco offers durability and natural patina development. For original aviation aesthetics, a navy or olive nylon NATO strap reconnects the chronograph to its military heritage.

Strap changes require a dedicated lever-operated spring bar tool to remove the spring bars seated in the lugs. The 3800ST lugs have curved geometry: it is recommended to have the operation performed by a watchmaker or specialized atelier to avoid scratching the satin-brushed case surfaces.

Yes. Any 20mm aftermarket strap is dimensionally compatible with the Breguet Type XX 3800ST/92/9W6. It is important to choose straps with flexible or curved-cut ends to accommodate the integrated lug geometry. Milano Straps offers a dedicated selection of 20mm straps, including custom artisanal options.

A quality leather strap—full-grain calfskin or vegetable-tanned alligator—typically lasts between 18 and 36 months with regular use, depending on exposure to sweat, moisture, and direct sunlight. Occasionally applying leather-specific conditioning cream and rotating between multiple straps significantly extends the lifespan of each piece. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
