Strap for Chronomat Automatic 36 South Sea Stainless Steel / Beige

The Breitling Chronomat 36 A10380611A1P1 has a lug width of 18 mm. This measurement is taken with a digital calliper positioned between the two lugs, flush against the case, without applying pressure. This is the correct measurement to specify when purchasing any compatible replacement strap.

For the Chronomat 36 in stainless steel, the most suitable straps are porosus alligator for formal occasions, shell cordovan for refined daily wear that develops a natural patina over time, or vegetable-tanned calf leather for maximum versatility. For sport or summer use, FKM rubber or an 18 mm NATO strap provide durability and lightness. A stainless steel deployant clasp maintains visual symmetry with the original Rouleaux bracelet.

To replace the strap on the Chronomat 36, you will need a fine-tipped spring bar tool. Insert the tool into the gap between the lug and the strap, compress the spring bar and slide the strap out laterally. Take care not to scratch the stainless steel case: it is advisable to protect the lugs with low-tack adhesive tape during the swap.

Yes. Any strap with an 18 mm attachment and standard spring bars is compatible with the Chronomat 36 A10380611A1P1. Milanostraps.it offers a curated selection of handcrafted 18 mm straps in various materials and finishes, made by Casati Milano or available online, with straight or curved ends to suit the geometry of the original lugs.

The lifespan of a leather strap depends on the material and conditions of use. A vegetable-tanned calf leather strap, worn daily, typically lasts 18 to 24 months. Shell cordovan, owing to its dense fibre structure, can exceed 3 to 4 years with regular conditioning. Handcrafted alligator straps, kept away from sweat and moisture, can maintain their structural and aesthetic integrity for over 5 years. Casati Milano provides an 18-month manufacturing warranty on all straps.
