Strap for Montbrillant Legende Black

The lug width of the Breitling Montbrillant A2334021.B871 is 20mm. This measurement should be taken with a digital calliper placed between the two lugs at the spring bar attachment point. Despite the 47mm case diameter, the lug width remains at 20mm, consistent with Breitling's tradition for classical chronographs.

For the Breitling Montbrillant A2334021.B871, the most suitable materials are alligator leather for its three-dimensional texture that complements the ridged bezel, shell cordovan for those seeking a tight grain and developing patina, and vegetable-tanned calf leather for everyday use. A steel deployant clasp is preferable to a standard pin buckle to distribute the weight of the 47mm case evenly across the wrist.

To replace the strap on the Breitling Montbrillant A2334021.B871, use a flat-blade or fork-type spring bar tool, inserting it between the lug and the strap end to compress the spring bar. Once released, slide out the old strap and fit the new one. Work on a soft surface to avoid scratching the stainless steel case. If in doubt, a watchmaker or the Casati Milano atelier can perform the swap safely.

Yes, the Breitling Montbrillant A2334021.B871 accepts any aftermarket strap with a 20mm lug width, provided the strap ends have a profile suited to the case's lug shape. For a curved case such as the Montbrillant, a curved or semi-curved strap end is recommended for a flush fit. Milano Straps offers a selection of compatible handcrafted 20mm straps, with full customisation available through the Casati Milano atelier.

The lifespan of a leather strap depends on the material and daily care. A quality alligator or shell cordovan strap, kept away from direct water contact and prolonged humidity, will maintain its structural and aesthetic integrity for 3 to 5 years with regular use. Vegetable-tanned leather responds well to conditioning with neutral wax. Milano Straps provides an 18-month warranty against manufacturing defects on all handcrafted straps.
