FAQ

What is the lug width of the Breitling Superocean A17366D71O1A1?

The lug width of the Breitling Superocean A17366D71O1A1 is 20mm. This measurement is taken with a digital calliper at the internal distance between the two lugs, at the point where the strap attaches to the case.

What is the best strap for the Breitling Superocean A17366D71O1A1?

The ideal strap depends on intended use. For formal or business occasions, a vegetable-tanned alligator strap with a steel deployant clasp is recommended. For aquatic or outdoor activities, vulcanised rubber or ballistic nylon NATO straps in 20mm are the most practical choice. The strap's tail must be curved to fit the integrated lugs correctly.

How do you change the strap on a Breitling Superocean A17366D71O1A1?

Use a springbar tool, inserting the tip into the lateral slot of the lug. Compress the springbar, slide the strap free, then reverse the procedure to fit the new strap. No specialist watchmaker is required, but care should be taken to avoid scratching the stainless steel case and lugs.

Are there aftermarket straps compatible with the Breitling Superocean A17366D71O1A1?

Yes. The Breitling Superocean A17366D71O1A1 accepts 20mm straps with a curved tail. Casati Milano produces bespoke aftermarket straps in alligator, calf, shell cordovan and rubber, all made with the appropriate curved tail to ensure a flush fit against the integrated lug design.

How long does a leather strap last on a Breitling Superocean A17366D71O1A1?

A high-quality leather strap — alligator or vegetable-tanned calf — typically lasts between 18 and 36 months with daily wear, depending on exposure to perspiration, water and heat. Regular conditioning and the use of a deployant clasp instead of a standard buckle will significantly extend the strap's service life.
