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

The lug width of the Breitling Colt A1338811.C914.228S/A20S.1 is 22mm. This measurement is taken with a digital calliper positioned internally between the two lugs, flush against the stainless steel case. Any strap with a 22mm attachment is fully compatible with this reference.

For the 44mm Breitling Colt, the most suitable options are vegetable-tanned calf leather (for a sport-elegant look with natural patina), alligator in black or tobacco (for semi-formal settings), vulcanised rubber (for aquatic or active use), and ballistic nylon NATO (to honour the model's military heritage). A brushed steel deployant clasp is recommended for chromatic coherence with the case.

To replace the strap, you will need a fine-tipped spring bar tool. Insert the tip into the lateral notch of the spring bar, compress it and slide one side out before removing the other. The operation takes approximately two minutes per side. It is advisable to work on a soft surface to avoid scratching the case or caseback.

Yes. The aftermarket offering for 22mm lug width is among the most extensive available. Milano Straps produces handcrafted compatible straps in leather, alligator, calf and rubber, using selected materials and hand-stitching. All available models are listed in the 22mm strap collection on the website, with bespoke customisation available through Casati Milano.

The lifespan of a leather strap depends on the hide, care and frequency of use. A quality vegetable-tanned calf strap worn daily typically lasts 2–4 years before replacement is needed. Alligator or shell cordovan straps, owing to the greater fibre density, can last 5–8 years with proper maintenance (nourishing cream, drying away from heat sources). Milano Straps offers an 18-month warranty against manufacturing defects.
