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

The lug width of the Breitling Colt A1338811/G804/105X/A20BA.1 is 22mm. This measurement is taken at the narrowest point between the case lugs and is the key parameter for selecting a compatible strap. A 22mm strap fits without lateral play or stress on the lugs.

The most suitable straps for the Breitling Colt A1338811/G804/105X/A20BA.1 are vegetable-tanned Tuscan calfskin for daily wear and natural patina development, matte-finish Mississippiensis alligator for a more formal register, and technical nylon NATO for fidelity to the model's military heritage. The choice depends on context and dial colour: the blue G804 dial pairs particularly well with dark brown or navy tones.

To replace the strap on the Breitling Colt A1338811/G804/105X/A20BA.1, use a flat-tip or double-fork springbar tool. Compress the spring bar within the lug slot, slide the strap tail laterally until the bar clears the lug hole, and remove the keeper. Work on a soft surface to avoid scratching the stainless steel case. The correct specification for this model is a 22mm stainless steel spring bar with a 1.8mm diameter.

Yes. The Breitling Colt A1338811/G804/105X/A20BA.1 uses a standard 22mm lug width, compatible with the vast majority of quality aftermarket straps. Milano Straps produces handcrafted straps in 22mm specifically for this lug size, using Italian leather, CITES-certified alligator, cordura and vulcanised rubber, with a curved keeper profile to sit flush against the Breitling case back.

The lifespan of a leather strap depends on the tanning quality, frequency of use, and maintenance routine. A vegetable-tanned Tuscan calfskin strap, when rotated with other straps and treated periodically with a natural leather conditioner, will maintain structural integrity and aesthetic appeal for 3–5 years of regular use. High-grade Mississippiensis alligator straps, thanks to the natural durability of the scale structure, can exceed 6–8 years. Milano Straps provides an 18-month guarantee against manufacturing defects.
