Strap for Colt 36 Diamond / Volcano Black / Sahara

The Breitling Colt A7438953.BD82.214X has a lug width of 18mm. This is the measurement required to select any compatible replacement strap, whether Breitling original or aftermarket.

For the 36mm steel Colt, a vegetable-tanned calfskin or Louisiana alligator strap best complements the model's elegant-instrumental character. Shell cordovan is ideal for intensive daily wear. For sporting contexts, a heavy nylon NATO strap preserves the Colt line's aeronautical identity.

The strap is removed using a spring bar tool. Compress the spring bars by inserting the tool into the gap between the lug and the strap, then slide the strap free and replace it with an 18mm width strap. The operation can be performed carefully at home or entrusted to a watchmaker.

Yes. Any strap with an 18mm lug width is technically compatible. Milanostraps.it offers a curated selection of handcrafted leather and other material straps available in this size, with customisable finishes also through the Casati Milano bespoke service.

Longevity depends on the material and frequency of use. A quality calfskin strap typically lasts 1–3 years with daily wear. Alligator and shell cordovan, owing to their dense fibre structure, can exceed 3–5 years with proper care. Casati Milano provides an 18-month warranty against manufacturing defects on all handcrafted straps.
