FAQ
What is the lug width of the Breitling Superocean A17366D21A1S1?
The Breitling Superocean A17366D21A1S1 has a lug width of 20mm. This measurement refers to the internal distance between the case lugs at the strap attachment point and should be confirmed on your specific example using a calliper, to rule out any later modifications.
What is the best strap for the Breitling Superocean A17366D21A1S1?
The ideal choice depends on intended use. For aquatic environments, a vulcanised rubber strap offers the most technical and durable solution. For mixed daily wear, a thick-grained calf leather or vegetable-tanned alligator provides character and resilience. A nylon NATO strap suits those who prefer a sporty aesthetic with quick-change versatility.
How do you change the strap on a Breitling Superocean A17366D21A1S1?
The strap is removed using a spring bar tool to release the spring bars from the case lugs. This is a straightforward operation that does not require professional assistance, though it should be carried out carefully on a soft surface to avoid scratching the case. Good lighting is recommended throughout.
Are there aftermarket straps compatible with the Breitling Superocean A17366D21A1S1?
Yes. Any strap with a 20mm attachment width is technically compatible with the Breitling Superocean A17366D21A1S1. Milanostraps.it offers a curated selection of handcrafted leather, rubber and nylon straps specifically sized for this lug width, with buckle or deployant clasp available on request.
How long does a leather strap last on a Breitling Superocean A17366D21A1S1?
The lifespan of a leather strap depends on tanning quality, frequency of use and exposure to perspiration and moisture. A high-grade alligator or calf leather strap worn daily in dry conditions can last between two and four years. Given the Superocean's aquatic vocation, it is advisable to reserve leather straps for dry-land use and alternate with a rubber strap for water activities.
