Strap for Colt Chronograph Automatic Stainless Steel / Stratus Silver / Bracelet

The Breitling Colt A13388111G1A1 features a 22mm lug width. This measurement refers to the internal distance between the two lugs on the case and determines compatibility with any aftermarket strap. It is the most common standard among professional sport chronographs and offers a wide selection of materials and styles.

For the Colt A13388111G1A1, a vegetable-tanned Tuscan calf leather strap in tobacco or havana brown is the most coherent choice given the military and instrumental character of the chronograph. Alternatively, an alligator strap with hornback grain combines elegance and visual robustness, whilst a nylon NATO strap maintains fidelity to the aviation heritage. For intensive use, vulcanised rubber with a deployant clasp is the most functional solution.

To replace the strap on the Colt A13388111G1A1, you will need a spring bar tool. The spring bars are located within the case lugs: simply press the ends with the tip of the tool to release the strap. The operation takes approximately two minutes and requires no professional tools. It is advisable to carry out the procedure on a soft surface to avoid scratching the case.

Yes, any strap with a 22mm lug width is compatible with the Breitling Colt A13388111G1A1. Artisan aftermarket straps, such as those produced by Casati Milano for milanostraps.it, offer the same constructive quality as original straps — often with greater personalisation in leather, colour, stitching and buckle — at more competitive prices and with the possibility of directly selecting the material.

The lifespan of a leather strap depends on the quality of the tanning and daily use. A vegetable-tanned Tuscan leather strap, properly maintained with periodic application of nourishing cream and rotated with other straps, can last between 3 and 5 years whilst developing an authentic and pleasing patina. High-quality alligator straps, with moderate use, can exceed 5 years. Milanostraps.it guarantees its artisan straps for 18 months against manufacturing defects.
