Strap for Colt Chronograph II Black / Bracelet

The lug width of the Breitling Colt A7338710BB49157A is 20mm. This measurement should be taken with a digital calliper between the two lugs, in contact with the spring bars, excluding the thickness of the lugs themselves. Respecting this dimension is essential to ensure a lateral-play-free fit.

For the 44mm Breitling Colt A7338710BB49157A, the most suitable materials are vegetable-tanned calf leather for daily wear, bombé alligator for formal occasions, and vulcanised rubber for sport or aquatic environments. Ballistic nylon NATO straps offer the most practical solution for quick swaps. The ideal choice depends on intended use and aesthetic register.

To replace the strap on the Breitling Colt A7338710BB49157A, you will need a spring bar tool or a dedicated lever screwdriver to remove the 20mm spring bars housed in the lugs. It is advisable to work on a soft surface to avoid scratching the case. If in doubt, entrust the operation to a watchmaker or the Casati Milano service.
