Strap for Chronomat Colt 41 Automatic Tempest Grey / Calf / Folding

The Breitling Colt A17313101F1X4 has a lug width of 20 mm. This measurement refers to the internal distance between the two lugs where the strap is fitted. Respecting this dimension is essential to ensure proper strap retention and a clean aesthetic on the wrist.

The ideal choice depends on usage and personal style. For everyday versatility, a 20 mm vegetable-tanned calf leather strap offers the most balanced option, transitioning seamlessly between casual and semi-formal settings while developing a personal patina over time. For water exposure or sports use, a vulcanised rubber strap is the most appropriate. For formal occasions, a Louisiana alligator strap with a polished grain provides an elegant contrast against the brushed steel case.

Strap replacement requires a fine-tipped springbar tool. The 20 mm springbars are released by pressing both ends inward, disengaging the strap from the lugs. The process takes approximately two minutes and requires no specialist tools, though it is advisable to work on a soft surface to prevent scratches to the case or crystal.

Yes. Any strap with a standard 20 mm attachment and springbars is compatible with the Breitling Colt A17313101F1X4. Milanostraps.it offers a curated selection of handcrafted 20 mm straps in leather, rubber and NATO, available either ready to ship or made to order. The overall strap length should also be verified against the wearer's wrist circumference.

Longevity depends on the material and conditions of use. A quality calf leather strap, worn daily with limited water exposure, typically lasts between 18 and 36 months. Shell cordovan, owing to its dense and compact structure, can exceed three years while retaining its shape. Alligator leather, when properly maintained with dedicated conditioners, offers a comparable lifespan. Frequent exposure to perspiration, water or heat will significantly shorten the life of any leather strap.
