Strap for Colt 44 Silver / Bracelet

The lug width of the Breitling Colt A7438710.G743.157A is 22mm. This measurement should be taken with a digital calliper between the inner lug shoulders, not across the outer case edges. This is the correct specification for sourcing any compatible replacement strap for this model.

For the 44mm stainless steel Breitling Colt A7438710.G743.157A, the most suitable materials are: matte alligator for formal occasions, vegetable-tanned calf leather for those seeking an authentic patina over time, nylon NATO for sport or travel use, and vulcanised rubber for aquatic environments. The ideal choice depends primarily on the intended context of wear.

To replace the strap on the Breitling Colt A7438710.G743.157A, use a fine-tipped or forked spring bar tool. Insert the tool into the spring bar slot, compress inward and slide the strap free. The original spring bars on this model are standard diameter — retain them for reinstalling the original strap. The operation can be carried out independently with the correct tools.
