Strap for Chrono Colt Silver / Bracelet

The lug width of the Breitling Colt A7338011.G597 is 20 mm. This measurement is taken at the narrowest point between the two lugs, closest to the case, using a digital calliper or a millimetre ruler. Any strap with a 20 mm attachment width is compatible with this reference.

The ideal choice depends on the intended use. For formal or business contexts, an alligator or vegetable-tanned calfskin strap with a pin buckle or deployant clasp complements the complexity of the Caliber B73. For intensive or sporting use, a ballistic nylon NATO or vulcanised rubber strap provides durability and comfort. The correct width is 20 mm.

The strap is replaced using a flat-tipped spring bar tool or a dedicated lug tool, applying gentle pressure to release the spring bar housed within the lugs. It is advisable to work on a soft surface to protect the case and crystal. If in doubt, consult a watchmaker or the Casati Milano atelier.

The lifespan of a leather strap depends on the material, care routine and frequency of use. A quality vegetable-tanned calfskin strap, conditioned periodically with a suitable leather cream and stored away from excessive moisture, typically lasts 2 to 4 years. Alligator, owing to its denser fibre structure, can last upwards of 5 years with regular use.
