Strap for Colt 36 Stratus Silver / Sahara / Folding

The Breitling Colt A7438911/G803/256X/A16D.1 has an 18mm lug width. This measurement should be taken with a digital calliper placed between the lugs at the strap attachment point, not across the outer width of the case.

For the 36mm Colt, the most coherent options are vegetable-tanned calf leather — which develops a natural patina over time — belly alligator for tailored contexts, and nylon NATO for a sporting look consistent with the model's military heritage. The correct width is 18mm at the lug end, tapering to 16mm at the buckle.

The Colt features standard spring bar attachments. Using a proper springbar tool, the original strap can be removed in seconds without risking scratches to the case. It is advisable to work on a soft surface and protect the lugs with masking tape before inserting the tool.

Yes. Any strap with an 18mm attachment width and standard length (120mm long section, 75mm short section) is compatible with the Colt 36mm. Milano Straps offers a curated selection of 18mm straps in various materials available directly online, as well as the option of a fully bespoke strap through Casati Milano.

A quality leather strap — vegetable-tanned calf or alligator — worn regularly will typically last 2 to 4 years, depending on perspiration levels, water exposure and frequency of use. Shell cordovan, thanks to its dense fibrous structure, tends to last longer and resists deformation at the flex points more effectively.
