FAQ
What is the lug width of the Breitling Superocean A17366021B1A1?
The lug width of the Breitling Superocean A17366021B1A1 is 20mm. This measurement should be taken between the inner walls of the case lugs at the strap attachment point, using a calliper or a millimetre gauge for maximum accuracy before purchasing a replacement strap.
What is the best strap for the Breitling Superocean A17366021B1A1?
For the Breitling Superocean A17366021B1A1, a vulcanised rubber strap is the most coherent choice given its diving heritage: waterproof and resistant to saltwater and chlorine. For everyday elegant wear, a matte alligator or a vegetable-tanned calf leather strap complements the stainless steel case without compromising its technical character. A NATO nylon strap is preferable for sporting or marine contexts.
How do you change the strap on a Breitling Superocean A17366021B1A1?
To replace the strap on the Breitling Superocean A17366021B1A1, use a dedicated spring bar tool or a thin flat-head screwdriver to compress and release the spring bars housed within the lugs. Lever gently to compress the spring bar ends and slide the old strap out. Insert the new strap ensuring both spring bars click audibly into their lug seats. Work on a soft surface to avoid scratching the case.
Are there aftermarket straps compatible with the Breitling Superocean A17366021B1A1?
Yes: any 20mm strap with standard spring bar attachment is compatible with the Breitling Superocean A17366021B1A1. Milanostraps.it offers a curated selection of handcrafted straps in leather, alligator, calf, rubber and NATO, made to measure for 20mm lugs, with bespoke stitching and finishing options available through the Casati Milano atelier.
How long does a leather strap last on a Breitling Superocean A17366021B1A1?
The lifespan of a leather strap depends on the quality of the hide and frequency of use. A high-quality vegetable-tanned calf strap, with regular care, typically lasts 2–4 years. Premium alligator and shell cordovan can last 5–8 years, developing a distinguished patina over time. Prolonged exposure to saltwater or perspiration accelerates deterioration: for aquatic use, a rubber strap is strongly recommended.
