Frequently asked questions

What is the lug width of the Breitling Colt A17388101B1X2?

The lug width of the Breitling Colt A17388101B1X2 is 22mm. This measurement refers to the internal distance between the two lugs of the case, where the strap is fitted. Before purchasing an aftermarket strap, it is advisable to verify this dimension directly on the case using a digital calliper to ensure a precise fit.

What is the best strap for the Breitling Colt A17388101B1X2?

The choice depends on intended use. For a sporting and professional aesthetic consistent with the Colt's DNA, a vulcanised rubber strap or a 22mm nylon NATO are the most functional options. For a more formal look, an alligator or vegetable-tanned calf leather strap fitted with a stainless steel deployant clasp enhances the proportions of the 44mm case without compromising its technical character.

How do you change the strap on the Breitling Colt A17388101B1X2?

The strap is replaced using a dedicated springbar tool or a flat spatula with a blunt tip. Insert the tool into the lateral groove of the lug, compress the spring bar, and slide the strap out. The operation is fully reversible and requires no intervention on the movement. With 22mm lugs, it is important to use springbars of the correct diameter and length to avoid scratching the case.

Are there aftermarket straps compatible with the Breitling Colt A17388101B1X2?

Yes. Any strap with a 22mm lug width is technically compatible with the Breitling Colt A17388101B1X2. milanostraps.it offers a handcrafted selection of leather, rubber and textile straps specifically made for this width, with thicknesses and finishes designed to complement the steel case of the Colt without compromising wrist ergonomics.

How long does a leather strap last on a Breitling Colt A17388101B1X2?

The lifespan of a leather strap depends on the quality of the tanning, usage and maintenance. A quality alligator or vegetable-tanned calf strap with waxed perimeter stitching can last between 3 and 7 years with daily wear. Prolonged exposure to water and perspiration accelerates deterioration: for a Colt used in humid or active environments, it is advisable to alternate with a rubber strap to preserve the leather one.
