Frequently asked questions

What is the lug width of the Breitling Superocean A1739102BA79145S?

The lug width of the Breitling Superocean A1739102BA79145S is 20mm. It should be measured using a digital calliper placed inside the lugs, at the point where the spring bar sits. This 20mm standard ensures broad compatibility with quality aftermarket straps.

What is the best strap for the Breitling Superocean A1739102BA79145S?

It depends on intended use. For a choice consistent with the watch's diving heritage, vulcanised rubber is the most appropriate: resistant, waterproof and comfortable on the wrist. For daily or business wear, a vegetable-tanned calfskin strap or a matte alligator strap paired with a steel deployant clasp enhances the Superocean's character without compromising its technical identity.

How do you change the strap on a Breitling Superocean A1739102BA79145S?

To remove the original strap, use a fine-tipped spring bar tool. Insert the tool into the notch on the side of the spring bar, compress the spring and slide the strap free from the lug. Care must be taken to avoid scratching the steel lugs. An experienced watchmaker can complete the swap in minutes, ensuring the spring bars are correctly tensioned.

Are there aftermarket straps compatible with the Breitling Superocean A1739102BA79145S?

Yes. Any strap with a 20mm lug width and straight ends is compatible with the Breitling Superocean A1739102BA79145S. Milano Straps offers a curated selection of handcrafted straps in leather, alligator, calfskin and rubber, made specifically for dive watches of this calibre, with finishes and stitching suited to the geometry of Breitling lugs.

How long does a leather strap last on a Breitling Superocean A1739102BA79145S?

Longevity depends on leather quality and usage. A premium vegetable-tanned calfskin strap, with regular use and proper care — avoiding prolonged water exposure and drying after contact with moisture — typically lasts between 2 and 4 years. A high-grade alligator strap can exceed 5 years. Milano Straps provides an 18-month warranty against manufacturing defects.
