Strap for Montbrillant Datora

The Breitling Montbrillant A2133012G518222A has a lug width of 22mm. This measurement refers to the internal distance between the lugs of the case, where the strap is fitted. It is essential to select a strap of exactly 22mm to ensure a proper fit and correct proportions.

Given the Montbrillant's aeronautical character and 43mm case, the most suitable materials are matte alligator leather for formal occasions and vegetable-tanned calf leather for an authentic vintage aesthetic. A NATO nylon strap is recommended for sportswear or summer use. The keeper and buckle should be in brushed steel to match the original case finish.

To replace the strap on the Montbrillant, you will need a springbar tool to remove the 22mm spring bars. Work on a soft surface to prevent scratching the case. Alternatively, the operation can be carried out by a watchmaker or at the Casati Milano atelier by appointment.

Yes, any strap with a 22mm lug width is technically compatible with the Montbrillant A2133012G518222A. Milano Straps offers a curated selection of handcrafted 22mm straps made in Italy, using materials such as alligator, vegetable-tanned calf leather and ballistic nylon, all suited to the stainless steel case of the Montbrillant.

The lifespan of a leather strap depends on the material, care and frequency of use. A quality vegetable-tanned calf strap, conditioned every 3–4 months, typically lasts 2–3 years. A premium alligator strap, with the same maintenance, can last over 5 years. Milano Straps provides an 18-month guarantee against manufacturing defects on all its straps.
