Strap for Montbrillant 01 Stainless Steel / Mercury Silver / Croco

The lug width of the Breitling Montbrillant AB013012.G709.728P is 20mm. This measurement is taken with a digital calliper placed between the horizontal lugs of the case. A strap measuring exactly 20mm ensures no lateral play and correct mechanical stress distribution across the lugs.

For the Montbrillant AB013012.G709.728P, a vegetable-tanned alligator strap with a stainless steel deployant clasp is the most coherent choice given the technical character of the case. Shell cordovan is an excellent alternative, offering a dense texture and superior longevity. For sports use or humid conditions, a 20mm ballistic nylon NATO strap provides functionality without compromising visual proportions.

To replace the strap on the Montbrillant AB013012.G709.728P, use a fine-tipped spring bar tool. Compress the spring bars laterally by applying gentle leverage within the lug channel. Work on a soft surface to avoid scratching the stainless steel case. If in doubt, entrust the operation to a qualified watchmaker or the Casati Milano atelier.

Yes. Any strap with a 20mm lug width is compatible with the Breitling Montbrillant AB013012.G709.728P, provided the spring bar housing suits the depth of Breitling's lugs. Milano Straps offers a curated selection of handcrafted 20mm straps manufactured to precise tolerances for a play-free fit.

The lifespan of a leather strap depends on the material, frequency of use, and maintenance. A quality vegetable-tanned alligator strap worn daily typically lasts 2–4 years before showing structural wear at the holes or stitching. Shell cordovan, owing to its fibre density, tends to outlast most other leathers. The Casati Milano warranty covers manufacturing defects for 18 months.
