Frequently asked questions

What is the lug width of the Breitling Colt A7738853/G793/133S/A14S.1?

The lug width of the Breitling Colt A7738853/G793/133S/A14S.1 is 16mm. This measurement should be taken with a digital calliper positioned inside the lugs, flush against the case, to ensure maximum accuracy before purchasing an aftermarket strap.

What is the best strap for the Breitling Colt A7738853/G793/133S/A14S.1?

For the 33mm Breitling Colt A7738853/G793/133S/A14S.1, an alligator Louisiane strap enhances the COSC chronometer certification of the movement, whilst a vegetable-tanned calf leather develops a personal patina over time. For intensive daily use, vulcanised rubber maintains dimensional stability and comfort. A steel deployant clasp coordinates well with the stainless steel case.

How do you change the strap on a Breitling Colt A7738853/G793/133S/A14S.1?

To replace the strap on the Breitling Colt A7738853/G793/133S/A14S.1, a springbar tool or fork-type tool is required. Compress the springbar by acting on the lateral notch, remove the strap, and fit the new one ensuring the pins are correctly seated in the lug holes. Take care not to scratch the stainless steel case during the operation.

How long does a leather strap last on the Breitling Colt A7738853/G793/133S/A14S.1?

The lifespan of a leather strap for the Breitling Colt A7738853/G793/133S/A14S.1 depends on leather quality and conditions of use.
