Strap for Chronomat Automatic 36 Stainless Steel / White / Rouleaux

The lug width of the Breitling Chronomat 36 A10380101A3A1 is 20mm. This measurement should be taken with a calliper at the point where the spring bar passes between the lugs. Adhering precisely to this dimension is essential for both mechanical security and visual harmony with the integrated case design.

The most suitable materials for the Breitling Chronomat 36 A10380101A3A1 are alligator with natural grain, vegetable-tanned calf leather, and shell cordovan. Alligator enhances the visual complexity of the rider tabs bezel, calf leather develops a patina that suits daily wear, whilst shell cordovan creates an elegant contrast with the mother-of-pearl dial. For sporting use, a vulcanised rubber strap in 20mm is the most functional choice.

To replace the strap on the Breitling Chronomat 36, a spring bar tool is required to compress and remove the spring bars securing the strap to the lugs. Insert the forked tip into the spring bar slot, compress inward and slide the bar free laterally. The Chronomat 36 features integrated lugs that require straps with curved ends to ensure a clean transition between strap and case. If in doubt, consult a watchmaker or contact Casati Milano for a professional fitting service.

The lifespan of a leather strap on the Breitling Chronomat 36 depends on the material and maintenance. A quality vegetable-tanned calf strap, regularly conditioned and rotated with other straps, typically lasts 2–4 years. Shell cordovan, owing to its dense fibre structure, can exceed 5 years. Exotic alligator, if kept away from prolonged water exposure, maintains its structure for 3–5 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
