Strap for Chronomat Automatic 36 Stainless Steel / Blue / Rouleaux

The lug width of the Breitling Chronomat 36 A10380101C1A1 is 18 mm. This measurement remains consistent along the full length of the lugs without significant tapering towards the caseback, making strap replacement straightforward with any straight-end strap measuring 18 mm at the lug.

For the Chronomat 36 A10380101C1A1 with a white dial, a vegetable-tanned alligator strap in midnight blue or cognac brown offers the most balanced combination of elegance and sporting character. For more active use, shell cordovan calf leather or vulcanised rubber with a granular texture provide excellent durability and comfort. A polished steel deployant clasp completes the aesthetic coherence with the stainless steel case.

To replace the strap on a Breitling Chronomat 36, you will need a fine-tipped spring bar tool or a thin flat-blade screwdriver to compress and release the spring bars fitted within the lugs. Insert the tool into the lateral notch of the spring bar, compress the spring and slide the strap free. Work on a soft surface to avoid scratching the case, and ensure the replacement spring bars are of the correct diameter for the 18 mm strap's keeper.

Yes, a wide range of aftermarket straps are compatible with the Breitling Chronomat 36, provided they feature a straight end and an 18 mm lug width. Milano Straps offers a curated selection of handcrafted leather, NATO, and rubber straps specifically calibrated to this size, manufactured with premium materials and bespoke finishing. Compatibility is ensured by the model's standard spring bar specification.

The lifespan of a leather strap depends on the material, care routine and frequency of wear. A well-maintained vegetable-tanned alligator strap—conditioned with leather cream every two to three months and stored in a dry environment—can last between three and five years with regular use. Shell cordovan, owing to its dense fibrous structure, offers superior resistance to moisture and abrasion, developing a patina that enhances its aesthetic longevity. Casati Milano straps carry an 18-month manufacturing warranty.
