Strap for Superocean Chronograph 42 Stainless Steel / Blue / Rubber / Pin

The lug width of the Breitling Superocean A13311D1/C971/225S/A18S.1 is 22mm. This measurement is taken with a digital calliper placed between the two lugs, against the case bezel, at the point where the strap inserts. Compatible straps must be 22mm at the lug end and may taper to 20mm or 18mm towards the buckle.

The ideal strap depends on the intended use. For marine or sport environments, a vulcanised rubber strap offers waterproofing and salt resistance. For urban or formal wear, a vegetable-tanned alligator strap in black or midnight blue enhances the case without compromising its character. A ballistic nylon NATO strap is the most versatile and hardwearing option for daily use.

To change the strap, you will need a springbar tool, available from watchmakers or online retailers. Insert the tip into the small notch on the side of the lug, compress the spring bar and slide the strap free. The process takes approximately two minutes per side and requires no specialist skills, though working on a soft surface is advisable to avoid scratching the stainless steel case.

Yes. Any strap with a 22mm lug width is technically compatible with the Breitling Superocean A13311D1/C971/225S/A18S.1. MilanoStraps offers a range of handcrafted 22mm straps in alligator, calf leather, rubber and NATO weaves, produced with selected materials and finished by hand. Ready-made options are available online, or a bespoke piece can be commissioned through the Casati Milano atelier.

The lifespan of a leather strap on a diving watch depends on exposure to water and perspiration. An alligator or vegetable-tanned calf leather strap, kept away from salt water and allowed to dry thoroughly after each use, can last between two and five years with regular care (conditioning cream every three to six months). For frequent underwater use, rubber or nylon NATO straps offer significantly greater longevity.
