Frequently asked questions

What is the lug width of the Breitling Colt A17313101G1A1?

The Breitling Colt A17313101G1A1 has a lug width of 20mm. This measurement is taken between the inner walls of the case lugs using a millimetre calliper. Any standard 20mm strap will be compatible with this reference.

What is the best strap for the Breitling Colt A17313101G1A1?

For the Colt A17313101G1A1, a vegetable-tanned calf leather strap is recommended for daily wear, whilst an alligator strap suits more formal occasions. A nylon NATO or vulcanised rubber strap is ideal for sporting contexts. The choice depends on the primary use and the dial colour of the watch.

How do you change the strap on a Breitling Colt A17313101G1A1?

The strap on the Colt A17313101G1A1 is removed using a springbar tool or a dedicated lever screwdriver to compress the springbars securing the strap to the lugs.

How long does a leather strap last on a Breitling Colt?

The lifespan of a leather strap depends on the quality of the tanning, daily usage, and maintenance.
