Frequently asked questions

What is the lug width of the Breitling Superocean A17366D81A1S2?

The Breitling Superocean A17366D81A1S2 features a 20mm lug width. This measurement is taken between the inner edges of the case lugs at the point where the strap attaches, and is best confirmed using a digital calliper for accuracy.

What is the best strap for the Breitling Superocean 42mm?

It depends on the context. For formal or business wear, a vegetable-tanned alligator strap in 20mm with a brushed steel buckle offers the most refined pairing. For water use or active sport, a vulcanised rubber or ballistic nylon NATO strap provides superior performance and longevity.

How do I change the strap on the Breitling Superocean A17366D81A1S2?

Use a spring bar tool — either a lever or pointed tip — to compress the spring bars connecting the strap to the case lugs. Work on a soft surface to protect the satin-finished case from scratches. The operation requires no specialist tools, though first-timers may prefer to have a watchmaker perform the change.

Are there aftermarket straps compatible with the Breitling Superocean 42mm?

Yes. Any strap with a 20mm lug width is technically compatible with the Breitling Superocean 42mm. Milanostraps.it offers a curated selection of handcrafted straps in leather, rubber, and NATO, all fitted with standard 20mm spring bars compatible with this case.

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

Longevity depends on the material and usage. A vegetable-tanned alligator strap, properly maintained and kept away from prolonged water exposure, can last between three and six years while developing a distinguished patina. Salt water and perspiration accelerate deterioration; for diving or intensive sport use, alternating with a rubber or NATO strap is strongly advisable.
