Breitling
Colt A7738853/G793/175A— lug 16mm

The Breitling Colt A7738853/G793/175A has a lug width of 16mm. This measurement is taken between the inner edges of the case lugs at their base using a digital calliper. It is a less common size in the contemporary market, so confirming the measurement before purchasing an aftermarket strap is strongly recommended.

For the 33mm Colt, the most suitable straps are alligator Belly or vegetable-tanned calf leather with a slim profile (1.8–2.2mm thickness), which complement the case proportions without overwhelming them. Shell cordovan is ideal for formal wear. For casual or sports use, a nylon NATO or vulcanised rubber strap are functional alternatives consistent with the Colt's instrumental character.

To replace the strap, use a spring bar tool — either a fork-end or pin-end type — to compress and remove the spring bars securing the strap to the lugs. Insert the tool tip between the lug wall and the spring bar end, compress, and slide the bar out. The operation takes only a few seconds but should be performed carefully to avoid scratching the case. Casati Milano also offers a strap fitting service at their atelier.

Yes. Any strap with a standard 16mm attachment and spring bars is compatible with the Breitling Colt A7738853/G793/175A. Milano Straps offers a curated selection of handcrafted straps in various leathers and finishes, available specifically in 16mm width, both bespoke and ready to ship.

A quality leather strap — whether vegetable-tanned calf or alligator — typically lasts between two and five years with daily wear, depending on care, perspiration, and moisture exposure. Shell cordovan straps tend to last longer due to the density of the leather fibre. Regular conditioning with a suitable leather cream will significantly extend the strap's lifespan.
