Strap for Colt 36 Pearl Diamond / Sahara / Folding

The lug width of the Breitling Colt A7438911/A771/249X/A16D.1 is 18 mm. This measurement should be taken using a calliper between the two lugs of the case, at the narrowest point available for the strap. Respecting this dimension is essential to ensure correct fitting and a visually proportionate profile for the 36 mm case.

Vegetable-tanned calf leather is the most versatile choice for the Colt: it develops an authentic patina over time and complements the blue dial naturally. For formal settings, a belly alligator strap with a regular grain elevates the watch while preserving its restraint. For sport or marine use, a vulcanised rubber strap offers durability and comfort. All straps must have an 18 mm lug width.

The strap is removed using a springbar tool, inserted into the lateral slot of the lugs to compress the spring bars and release the strap. The operation takes approximately two minutes and can be performed without sending the watch to a service centre. It is advisable to rest the case on a soft cloth to avoid scratches to the case or crystal.

The lifespan of a leather strap depends on the quality of the hide, frequency of use and exposure to moisture and perspiration. A high-quality vegetable-tanned calf strap, worn daily and maintained periodically with appropriate conditioners, can last between 2 and 4 years. Alligator, due to the density of its leather fibres, tends to be more durable. Shell cordovan is amongst the most long-lasting materials available for watch straps.
