Strap for Colt Chronograph Automatic Stainless Steel / Volcano Black / Rubber / Pin

The lug width of the Breitling Colt A1338811/BD83/227S/A20S.1 is 22mm. This measurement is taken with a digital calliper positioned between the two lugs at the base of the case, measuring the internal distance between the horns. It is a standard dimension within the 44mm sport-professional segment.

For the 44mm Colt, the most coherent choices with the model's DNA are a vulcanised rubber strap for sporting use and a vegetable-tanned calf leather strap for a more formal register. A flat-belly alligator strap with a stainless steel deployant clasp delivers the greatest aesthetic impact for important occasions. In all cases the correct lug width is 22mm.

Strap replacement requires a 22mm spring bar and a fine-tipped springbar tool. Insert the tool into the lateral notch of the lug, compress the spring-loaded pin and slide out the bar. The operation is fully reversible and does not require any intervention on the watch movement. It is advisable to rely on a watchmaker or experienced strap specialist to avoid scratching the brushed stainless steel case.

Yes, the standard 22mm lug width ensures full compatibility with a wide range of aftermarket straps. Milano Straps offers handcrafted straps in leather, alligator, calf and technical materials specifically selected for the 22mm lug, available online or customisable to order at the Casati Milano atelier.

The longevity of a leather strap depends on the quality of the hide, the tanning method and daily use. A vegetable-tanned calf leather strap, maintained with a nourishing cream and kept away from prolonged water exposure, has an average useful life of 18 to 36 months. Vegetable-tanned alligator straps, owing to the density of their fibres, tend to last considerably longer. Milano Straps provides an 18-month guarantee against manufacturing defects.
