Frequently asked questions

What is the lug width of the Breitling Superocean A17367021I1A1?

The Breitling Superocean A17367021I1A1 features a 20mm lug width. This measurement is taken between the two lugs of the case using a digital calliper, at the base of the strap attachment point. It is a widely used standard that ensures broad compatibility with quality aftermarket straps.

What is the best strap for the Breitling Superocean A17367021I1A1?

The ideal choice depends on the intended use. For formal settings, a vegetable-tanned alligator strap with natural grain provides an elegant contrast to the steel case. For aquatic or sporting use, a vulcanised rubber strap is the most functional option. A nylon NATO strap remains the choice most faithful to the tool-watch character of the Superocean.

How do I change the strap on the Breitling Superocean A17367021I1A1?

To replace the strap or bracelet, a springbar tool is required to remove the spring bars securing the strap within the lugs. Care must be taken to avoid scratching the steel lugs: it is advisable to protect the case with masking tape or a soft cloth during the procedure.

Are there aftermarket straps compatible with the Breitling Superocean A17367021I1A1?

Yes. Any strap with a 20mm attachment width is compatible with the Breitling Superocean A17367021I1A1. Milano Straps offers a selection of handcrafted leather, rubber and nylon straps in 20mm, made from carefully sourced materials and hand-finished at the Casati Milano atelier.

How long does a leather strap last on a dive watch like the Superocean?

A quality leather strap — particularly in vegetable-tanned alligator or shell cordovan — typically lasts between 2 and 4 years with daily wear, provided it is not regularly exposed to water. For aquatic use, a rubber or nylon NATO strap is preferable. Leather is best reserved for dry conditions, where the Superocean performs equally well as an everyday sports watch.
