Strap for Colt Chronograph Automatic Stainless Steel / Mariner Blue / Calf / Folding

The lug width of the Breitling Colt A1338811/C914/436X/A20D.1 is 22 mm. This measurement should be taken directly between the case lugs using a digital calliper, at the strap attachment point, to ensure a precise fit and correct functioning of the keeper.

For the Breitling Colt A1338811/C914/436X/A20D.1 with its 44 mm case, the most suitable materials are vegetable-tanned calf leather for everyday wear — it develops a distinctive patina over time — flat-grain alligator for formal settings, and vulcanised rubber for sports or marine environments. The choice of material depends on intended use and the desired chromatic pairing.

Strap replacement requires a spring bar tool to release the spring bars securing the strap to the lugs. It is advisable to work on a protected surface to avoid scratching the case. Alternatively, a watchmaker or the Casati Milano atelier can carry out the replacement professionally, also checking the integrity of the original spring bars.

Yes. The Breitling Colt A1338811/C914/436X/A20D.1 features standard 22 mm lugs, compatible with any aftermarket strap made to that width. On milanostraps.it you will find handcrafted straps in leather, alligator, rubber and NATO specifically selected for 22 mm lugs, with stainless steel or deployant buckles.

The lifespan of a leather strap depends on the quality of the tanning, frequency of use, and exposure to perspiration and moisture. A quality vegetable-tanned calf leather strap, with daily use and regular care, typically lasts between 18 and 36 months. Alligator or shell cordovan straps, owing to the density of their fibres, tend to last longer while retaining their shape. The Casati Milano warranty covers manufacturing defects for 18 months.
