FAQ
What is the lug width of the Breitling Superocean A17366D71O1S2?
The lug width of the Breitling Superocean A17366D71O1S2 is 20mm. This measurement refers to the internal distance between the case lugs at the spring bar attachment point. Fitting any strap with this exact width ensures correct mounting and maintains the proportional integrity of the case.
What is the best strap for the Breitling Superocean A17366D71O1S2?
The ideal choice depends on intended use. For aquatic or sport use, a vulcanised rubber strap in 20mm is the most technically appropriate option. For urban or formal wear, vegetable-tanned alligator or fine-grain calf leather creates an elegant contrast against the satin-finished steel case. A nylon NATO strap remains the classic solution for those who wish to honour the tool watch heritage of the Superocean.
How do you change the strap on a Breitling Superocean A17366D71O1S2?
To replace the strap on the Superocean A17366D71O1S2, you need to remove the spring bars connecting the strap to the case lugs. Use a spring bar tool — a forked or lever-tip instrument — inserted into the slot on the side of the lug. Compress the spring bar gently and slide the strap free. Fitting the new 20mm strap is the reverse process; ensure both spring bars click firmly into place before wearing the watch.
Are there aftermarket straps compatible with the Breitling Superocean A17366D71O1S2?
Yes. Any strap with a 20mm lug width is technically compatible with the Breitling Superocean A17366D71O1S2. Milano Straps offers a curated range of handcrafted leather, rubber and textile straps in this width, proportioned for professional-grade cases in this segment. It is also advisable to check the total strap length — standard 120/75mm or long 130/85mm — according to your wrist circumference.
How long does a leather strap last on a dive watch like the Superocean?
The lifespan of a leather strap depends on exposure to water, perspiration and UV radiation. On a diver such as the Superocean, regular use in salt water or swimming pools will significantly reduce the strap's longevity — potentially to just a few months. A quality alligator or vegetable-tanned calf strap, used exclusively in dry conditions, can last between three and seven years with proper care. For aquatic use, rubber or NATO straps are recommended, reserving leather for urban wear.
