Strap for Type XXI 3815 Titanium / Black - Orange

The Breguet Type XX 3815TI/HO/3ZU is fitted with a 22mm lug width. This is the measurement to specify when purchasing any aftermarket or custom strap compatible with this reference.

It depends on the intended use. For formal contexts, a matte midnight blue or tobacco brown alligator strap complements the smoked dial and titanium finishing. For versatile daily wear, anthracite grey smooth calfskin is the most coherent choice with the aviation aesthetic. For those seeking military authenticity, a two-tone nylon NATO strap is the most faithful to the Type XX tradition.

The strap is replaced using a spring bar tool—a flat-forked implement—to remove the spring bars that secure the strap to the lugs. The operation takes only a few minutes and requires no professional equipment, but to avoid any risk of scratching the titanium case, it is advisable to entrust the work to a watchmaker or the Casati Milano atelier.

Yes. Any strap with a 22mm lug width is physically compatible with the Breguet Type XX 3815TI/HO/3ZU. Milano Straps offers a selection of custom-made 22mm straps in various materials—leather, alligator, NATO, and rubber—crafted to quality standards appropriate for a watch in this category.

A quality leather strap, on a 42mm watch worn regularly, typically lasts 18–36 months before stitching or the flex zone shows visible signs of wear. Lifespan depends on tanning quality, leather thickness, and exposure to perspiration and weather. Casati Milano straps are guaranteed for 18 months against manufacturing defects.
