Strap for Superocean Heritage B31 Automatic 42 Stainless Steel / Black / Milanese

The Breitling Superocean Heritage AB3111241B1A1 features a lug width of 22mm. This measurement can be confirmed using a digital calliper by measuring the inner distance between the two lugs at the point where they meet the case. Any standard 22mm strap with straight spring bars fits without adapters.

The ideal choice depends on intended use. For a refined look, a black alligator or vegetable-tanned brown calfskin strap works beautifully against the ceramic case. For maritime or sports use, vulcanised rubber offers the best practicality. A technical nylon NATO strap reinforces the tool watch heritage of the Superocean.

Strap replacement requires a spring bar tool to compress the spring bars housed within the 22mm lugs. It is advisable to work on a soft surface to protect the ceramic case from scratches. If in doubt, a qualified watchmaker or the Casati Milano atelier can perform the swap in a matter of minutes.

Yes. Any 22mm strap with standard spring bars is compatible with the Superocean Heritage AB3111241B1A1. Milano Straps offers a range of handcrafted leather, rubber and nylon straps sized specifically for 22mm lugs, available both online and bespoke through the Casati Milano atelier.
