Strap for Colt Chronograph Automatic Stainless Steel / Mariner Blue / Rubber / Pin

The lug width of the Breitling Colt A1338811/C914/145S/A20S.1 is 22mm. This measurement refers to the internal distance between the two lugs of the case, measured perpendicularly to the vertical axis of the watch. Any strap with a 22mm attachment width is fully compatible with this reference.

For the 44mm stainless steel Breitling Colt, the most fitting options are: vegetable-tanned Tuscan calf leather in a vintage finish for a warm, characterful tone; ballistic nylon NATO for fidelity to its military aesthetic; alligator for more formal occasions; and FKM rubber for intensive sporting use. The lug width is 22mm in all cases.

To replace the strap, remove the spring bars — the small pins securing the strap to the lugs — using a dedicated springbar tool. Insert the tip of the tool into the notch on the side of the spring bar, compress it and slide the strap free. The process is fully reversible and requires no intervention on the watch itself. Take care not to scratch the brushed or polished lug surfaces.

Yes, the aftermarket for 22mm straps is extensive. MilanoStraps offers a curated selection of handcrafted leather, rubber and nylon straps compatible with the Breitling Colt A1338811/C914/145S/A20S.1. Each strap can be personalised in terms of buckle style — standard or deployant clasp — and lug length.

The lifespan of a leather strap depends on leather quality, care and frequency of use. A high-quality vegetable-tanned Tuscan calf strap, with moderate daily wear and proper maintenance — rotating between straps, avoiding prolonged exposure to moisture — can last between two and four years while retaining an attractive patina. MilanoStraps straps carry an 18-month warranty against manufacturing defects.
