Frequently asked questions

What is the lug width of the Breitling Superocean A173678A1B1A1?

The Breitling Superocean A173678A1B1A1 features a 20mm lug width. This measurement refers to the internal distance between the two lugs of the case, best verified using a digital calliper placed directly against the case. Any standard 20mm strap will be compatible with this reference.

What is the best strap for the Breitling Superocean A173678A1B1A1?

The choice depends on the intended context. For a refined urban aesthetic, a vegetable-tanned alligator strap in matte finish complements the Superocean's instrumental character. For marine or active use, vulcanised rubber or nylon NATO straps offer durability and comfort. Shell cordovan develops a unique patina over time for those seeking exclusivity.

How do I change the strap on the Breitling Superocean A173678A1B1A1?

Strap replacement requires a fine-tipped spring bar tool. Insert the tool into the spring bar slot on the lug side, compress the spring bar and slide the strap free. It is advisable to work on a soft mat to prevent scratching the stainless steel case. If in doubt, the operation can be carried out by a watchmaker or at the Casati Milano atelier.

Are there aftermarket straps compatible with the Breitling Superocean A173678A1B1A1?

Yes. The Breitling Superocean A173678A1B1A1 uses a standard 20mm lug width, making it compatible with any aftermarket strap in that size with straight ends. Milano Straps offers a curated selection of handcrafted leather, rubber and nylon straps specifically designed for this lug format, with finishes consistent with the Superocean's aesthetic.

How long does a leather strap last on a Breitling Superocean A173678A1B1A1?

The lifespan of a leather strap depends on the material, tanning process and frequency of use. A quality vegetable-tanned alligator strap, maintained regularly with a nourishing cream, will retain its structural integrity for 3 to 5 years of daily wear. Prolonged exposure to salt water or perspiration accelerates deterioration: for marine contexts, a rubber or NATO strap is the more practical choice.
