Strap for Chronomat Automatic 36 Stainless Steel / Red Gold / White / Rouleaux

The Breitling Chronomat 36 U10380101A1U1 has a lug width of 16 mm. This measurement refers to the internal distance between the two case lugs at the point where the strap or bracelet attaches. It is advisable to verify this measurement with a vernier calliper before purchasing any aftermarket strap.

For the Chronomat 36 in stainless steel and red gold, an alligator strap in vegetable-tanned leather in burgundy or cognac tones best complements the warm two-tone case. Shell cordovan offers the most technically durable option, whilst box calf develops a distinctive patina over time. For sporting use, vulcanised rubber provides superior comfort and resistance.

Strap replacement requires removing the spring bars housed within the lugs. Use a spring bar tool with a fine tip, inserting it into the notch on the side of the spring bar to compress it and slide the strap free. For the Chronomat 36, spring bars of 16 mm diameter appropriate to the lug depth are recommended. Care should be taken to avoid scratching the two-tone case during the operation.

Yes. Any strap with a head width of 16 mm and standard spring bars is technically compatible with the Chronomat 36 U10380101A1U1. Milano Straps offers a curated selection of handcrafted straps in 16 mm width, available in alligator, calf leather, shell cordovan, nylon and rubber, with bespoke customisation options through the Casati Milano atelier.

Longevity depends on the material and conditions of use. A quality vegetable-tanned alligator strap, properly conditioned with leather cream and kept away from excessive perspiration and water, can last between 3 and 5 years. Shell cordovan, owing to its dense fibrous structure, tends to outlast most other leathers. Vulcanised rubber straps typically exceed 5 years under normal conditions of wear.
