Strap for Colt Quartz Silver / Bracelet

The lug width of the Breitling Colt A7438010.G598.812A is 20 mm. This measurement refers to the internal distance between the two lugs of the case and determines compatibility with any standard 20 mm aftermarket strap.

The choice depends on the intended context. For formal wear, a vegetable-tanned alligator strap with a deployant clasp is the most refined option. For daily or sporting use, a grained calf leather strap or a ballistic nylon NATO provides durability and comfort whilst respecting the tool watch character of the Colt.

The strap is removed using a springbar tool — a bifurcated tip instrument — which compresses the springs inside the lugs. Insert the tip into the lateral hole of the lug or between the strap and the case, compress the spring and slide the strap out. Care should be taken not to scratch the case; if in doubt, consult a watchmaker.

Yes. Any strap with a 20 mm attachment width is compatible with the Breitling Colt A7438010.G598.812A. Milanostraps.it offers a selection of handcrafted straps in alligator, calf leather, shell cordovan and rubber, all available in 20 mm, with a bespoke option through Casati Milano.

Longevity depends on leather quality, frequency of use and exposure to perspiration and moisture. A high-quality leather strap — such as shell cordovan or vegetable-tanned alligator — can last between 3 and 7 years with proper care. Avoiding water immersion and occasionally applying a neutral conditioner significantly extends the strap's lifespan.
