FAQ

What is the lug width of the Breitling Colt A7338710C848105X?

The lug width of the Breitling Colt A7338710C848105X is 20mm. This measurement is taken with a digital calliper across the internal gap between the two lugs at the point where the strap attaches to the case.

What is the best strap for the Breitling Colt A7338710C848105X?

For the Breitling Colt A7338710C848105X, the most coherent choices with the watch's instrumental character are: flat-grain alligator with a matte finish for a dress-sport register, vegetable-tanned calfskin to develop a natural patina over time, nylon NATO for aeronautical authenticity, and vulcanised rubber for outdoor use. A steel deployant clasp is recommended for a more secure fastening and optimal pressure distribution across the lug.

How do you change the strap on a Breitling Colt A7338710C848105X?

To replace the strap on the Breitling Colt A7338710C848105X, you need a fine-tipped spring bar tool. Insert the tool into the spring bar slot between the lug and the strap, compress the spring bar and slide it out. Care should be taken to avoid scratching the stainless steel case. Alternatively, Casati Milano offers a strap-fitting service by appointment at the Milan atelier.

Are there aftermarket straps compatible with the Breitling Colt A7338710C848105X?

Yes. The Breitling Colt A7338710C848105X features standard 20mm lugs, fully compatible with aftermarket straps from any manufacturer respecting this width.

How long does a leather strap last on a Breitling Colt A7338710C848105X?

The longevity of a leather strap depends on hide quality, tanning method and daily use. A quality vegetable-tanned calfskin strap, properly maintained with a leather conditioner every three to four months and kept away from heat sources, can last between two and five years. High-grade alligator straps, thanks to the compact structure of the scales, typically offer greater durability. Milano Straps provides an 18-month warranty against manufacturing defects on all Casati Milano straps.
