Strap for Colt Chronograph Automatic Stainless Steel / Stratus Silver / Calf / Pin

The lug width of the Breitling Colt A13388111G1X1 is 22mm. This measurement is taken internally between the two lower lugs using a calliper. Any strap with a 22mm attachment is compatible with this reference.

The ideal choice depends on intended use. For everyday elegant wear, a vegetable-tanned grained calfskin strap at 3–3.5mm thickness offers the best balance. For sport or aquatic environments, a ballistic nylon NATO or vulcanised rubber strap provides superior resilience. For a formal, characterful pairing, hornback alligator with a steel deployant clasp is the most refined option.

The strap is removed using a fine-tipped springbar tool inserted into the lateral lug hole to compress the retaining springs. No case opening or specialist watchmaking skills are required, but it is advisable to work on a soft surface to avoid scratching the caseback or case flanks.

Yes. Any strap with a 22mm attachment width is geometrically compatible with the Breitling Colt A13388111G1X1. Milano Straps offers a curated range of handcrafted leather, NATO, rubber and technical material straps dimensioned specifically for this lug width and finished to complement the Colt's stainless steel case.

Longevity depends on leather quality and frequency of use. A quality vegetable-tanned calfskin strap typically lasts 2–4 years with regular wear, provided it is kept away from prolonged water exposure and perspiration. Shell cordovan, owing to its dense, pore-free structure, offers superior durability. Milano Straps straps carry an 18-month warranty against manufacturing defects.
