Strap for Breitling for Bentley Flying B No. 3 Bronze

The Breitling for Bentley A1636212.Q551 has a lug width of 20mm. This measurement is taken internally between the two lugs at their narrowest point, where the strap makes contact with the case. A calliper provides the most accurate reading before purchasing a replacement strap.

An alligator strap with Mississippiensis grain best complements the haute horlogerie character of the Breitling calibre 16B. Alternatively, a vegetable-tanned calfskin strap develops a distinctive patina over time. For more active use, vulcanised rubber or a heavyweight nylon NATO strap offer functional durability. The correct width remains 20mm throughout.

Strap replacement requires a springbar tool with a tip diameter of 1.0–1.2mm. Insert the tool into the lateral hole of the lug to compress the springbar, then slide out the original strap. The operation is fully reversible and does not require opening the case. Work on a soft surface to avoid scratching the stainless steel case.

Yes. Any aftermarket strap with a straight-ended 20mm lug width is compatible with the Breitling for Bentley A1636212.Q551. The 20mm straps selected by milanostraps.it are verified against Breitling lug geometry, ensuring no lateral play and a precise fit on the original case.

Leather strap longevity depends on usage frequency, perspiration and maintenance. Under regular wear conditions, a quality vegetable-tanned calfskin strap typically lasts between 18 and 36 months. Alligator, due to its denser fibre structure, tends to last longer when kept away from prolonged moisture. Shell cordovan, thanks to its extremely tight grain, is among the most durable leathers available.
