Strap for Montbrillant 01 Stainless Steel / Mercury Silver / Croco

The lug width of the Breitling Montbrillant AB013012.G735.724P is 20 mm. To verify this, use a digital calliper to measure the internal gap between the lugs directly on the case. This dimension is compatible with any 20 mm aftermarket strap fitted with a standard pin buckle or deployant clasp.

The Breitling Montbrillant AB013012.G735.724P pairs well with several strap types. For daily wear, a vegetable-tanned calfskin strap in brown or black offers durability and a fine patina over time. Mississippi alligator is recommended for formal settings. A woven nylon NATO strap respects the instrument-oriented, aviation heritage of the watch. Shell cordovan is the premium choice for superior wear resistance.

To replace the strap on the Breitling Montbrillant AB013012.G735.724P, use a spring bar tool or a fine-tipped screwdriver. The 20 mm lugs accommodate standard 20 mm spring bars. Work on a scratch-free mat with the case face down, compressing the spring bar pins inward to release them from the lug holes. No watchmaker intervention is required for this operation.

The lifespan of a leather strap depends on material quality and care. A quality vegetable-tanned calfskin strap, kept away from excessive moisture and perspiration, typically lasts 2–4 years with daily wear. Alligator leather, thanks to its dense scale structure, tends to last longer under the same conditions. Casati Milano straps carry an 18-month guarantee against manufacturing defects.
