Strap for Colt Chronograph Stratus Silver / Rubber / Pin

The lug width of the Breitling Colt A7338811/G790/158S/A20S.1 is 22mm. This measurement should be taken with a digital calliper positioned on the inner edge between the two lugs, on the side opposite the bezel. This is the correct reference dimension for selecting any compatible aftermarket strap.

Given the instrument-oriented character of this model, the most coherent options are: premium nylon NATO for daily and sporting use, vegetable-tanned alligator for formal contexts, box-calf leather for everyday wear with developing patina, and vulcanised rubber for aquatic environments. All straps must feature a 22mm proximal end to fit the lugs correctly.

The strap is removed using a spring bar tool — either a flat-blade or forked-tip type — inserted into the hole of the spring bar connecting the strap to the case lug. Apply gentle inward pressure to compress the spring bar and slide the strap free. Care should be taken to avoid scratching the case; alternatively, a watchmaker or specialist atelier can perform the swap in a matter of minutes.

Yes. The Breitling Colt A7338811/G790/158S/A20S.1 uses a standard spring bar attachment system with a 22mm lug width, compatible with the vast majority of quality aftermarket straps. Milano Straps offers a curated range of handcrafted leather, alligator, NATO and rubber straps specifically sized for 22mm lugs, typically tapered to 20mm at the buckle end.

Longevity depends on the material, frequency of wear, and maintenance. A quality vegetable-tanned calf leather strap, with moderate daily use, typically lasts between 18 and 36 months before requiring replacement. Well-tanned alligator can last considerably longer when kept away from water and perspiration. Storing unused straps in a dry environment away from direct sunlight significantly extends the leather's service life.
