FAQ

What is the lug width of the Breitling Superocean A1736402BA31132S?

The Breitling Superocean A1736402BA31132S has a lug width of 22mm. This is a model-specific measurement and should be confirmed with a digital calliper placed inside the lugs, against the case, before purchasing any aftermarket strap.

What is the best strap for the Breitling Superocean A1736402BA31132S?

The ideal choice depends on intended use. For daily urban wear, a vegetable-tanned calfskin or alligator strap with a deployant clasp complements the technical character of the case. For sport or aquatic use, a ballistic nylon NATO or vulcanised FKM rubber strap offers the best functionality and remains consistent with the Superocean's diving heritage.

How do you change the strap on the Breitling Superocean A1736402BA31132S?

The original Ocean Racer integrated bracelet is removed via the screws securing it to the lugs. To fit a standard aftermarket strap with spring bars, confirm that the case lugs accept 22mm spring bars of the correct diameter. Use a dedicated spring bar tool and take care not to scratch the steel case during the process.

Are there aftermarket straps compatible with the Breitling Superocean A1736402BA31132S?

Yes. Any aftermarket strap with a 22mm attachment width is compatible with the Breitling Superocean A1736402BA31132S, provided the spring bars are of the correct diameter for this model's lugs. Milanostraps.it offers a curated selection of handcrafted 22mm straps in leather, alligator, nylon and rubber, made specifically for this lug width.

How long does a leather strap last on the Breitling Superocean A1736402BA31132S?

Longevity depends on material and usage. A quality vegetable-tanned calfskin strap, kept dry and conditioned regularly, typically lasts 2–4 years. Frequent exposure to salt water or perspiration significantly shortens the lifespan of any leather strap; in such conditions, rubber or NATO straps are strongly recommended. Casati Milano straps carry an 18-month warranty against manufacturing defects.
