Strap for Colt 36 Diamond / Mariner Blue / Bracelet

The Breitling Colt A7438953|C913|178A has a lug width of 18mm, measured as the internal distance between the case lugs at the strap attachment point. This is the correct measurement to use when selecting any compatible strap, whether in leather, rubber or NATO nylon.

For the stainless steel Colt A7438953|C913|178A at 36mm, the most appropriate choices are: matte alligator in black or midnight blue for a formal-instrumental register, shell cordovan in cognac or burgundy for a warm chromatic contrast, or fine-textured vulcanised rubber for sporting use. The 18mm lug width tapering to 16mm at the buckle ensures optimal proportion on the wrist.

The strap on the Colt A7438953|C913|178A is secured by standard 18mm spring bars fitted into the case lugs. A thin-blade springbar tool is sufficient to compress the bars and release the existing strap. It is advisable to work on a soft surface to avoid scratching the satin-finished steel case. The operation requires no specialist tools and can be completed in a few minutes.

Yes: any strap with an 18mm lug width and standard spring bars is compatible with the Colt A7438953|C913|178A. The aftermarket offers a considerably wider range than official Breitling straps, with extensive options for leather type, colour, stitching and clasp style. Milanostraps.it offers a selection of handcrafted 18mm straps, with bespoke options available through the Casati Milano atelier.

A well-crafted vegetable-tanned leather strap worn daily on a Breitling Colt will typically last between 2 and 5 years, depending on exposure to perspiration, water and heat. Shell cordovan tends to last longer due to the density of its fibres; alligator leather requires periodic conditioning with a nourishing cream to preserve its grain and texture. Casati Milano offers an 18-month guarantee against manufacturing defects.
