Strap for Colt 36 Diamond / Pearl Diamond / Sahara

The Breitling Colt A7438953.A771.239X has a lug width of 18mm. This measurement is taken using a digital calliper positioned between the two lugs at the narrowest point where the strap attaches to the case. Any compatible strap must have an 18mm attachment end.

For the Colt 36mm in brushed stainless steel, a square-scale alligator strap with a matte or semi-gloss finish is the most coherent choice with the case's professional aesthetic. A vegetable-tanned calfskin strap is an excellent alternative, as it develops a personal patina over time that complements the military character of the model. For sport use, vulcanised rubber offers durability and comfort without compromise.

Strap replacement requires a 1.2mm spring bar tool. Insert the tip into the lateral notch of the spring bar between the lug and the strap, compress the spring, and slide the bar out. Repeat on both sides. It is advisable to work on a soft pad to avoid scratching the case. The new 18mm strap is fitted in reverse order.

Yes. The Breitling Colt A7438953.A771.239X uses a standard 18mm lug attachment, compatible with a wide range of artisan aftermarket straps. Milano Straps offers handcrafted options in alligator, calfskin, shell cordovan and rubber, all sized for 18mm lug width, with finishing standards comparable or superior to the original factory strap.

The lifespan of a leather strap depends on hide quality, tanning method and daily use. A high-grade alligator or vegetable-tanned calfskin strap used daily typically lasts between 18 and 36 months. Longevity is extended by avoiding prolonged exposure to water and perspiration, and by treating the leather periodically with appropriate conditioning products. Casati Milano straps carry an 18-month warranty against manufacturing defects.
