Strap for Colt 36 Diamond / Mariner Blue / Rubber

The lug width of the Breitling Colt A7438953.C913.238S is 18mm. This measurement should be taken with a digital calliper at the inner contact point between the case lugs and the strap, ensuring a precise fit with no lateral play.

For the Colt 36mm, vegetable-tanned calf leather or matte alligator are the most coherent choices given the tool-watch aesthetic of the brushed steel case. For sporting or marine use, a vulcanised rubber strap offers durability and practicality. A two-colour NATO is ideal for a field-watch register.

To replace the strap on the Colt A7438953.C913.238S, you will need a springbar tool: insert the tip into the lug slot, compress the spring bar and slide the strap free. Care should be taken to avoid scratching the brushed case; placing a soft cloth around the lugs as protection is advisable.

Yes. Any strap with an 18mm lug width and standard spring bars is compatible with the Breitling Colt A7438953.C913.238S. On milanostraps.it you will find a curated selection of handcrafted 18mm straps in various materials, with straight or tapered ends, available with a buckle or deployant clasp in brushed steel.

The lifespan of a leather strap depends on the material, the tanning process and daily use. A quality vegetable-tanned calf strap, with normal rotation, typically lasts 2–4 years. Shell cordovan and alligator have a denser, more resilient structure and tend to last considerably longer. Regular conditioning and avoiding prolonged water exposure will significantly extend the strap's life.
