Strap for Superocean 42 Stainless Steel / Black - Red / eComm

The Breitling Superocean A17366D71B2S1 has a lug width of 20mm. This measurement, taken with a digital calliper positioned internally between the two case lugs, determines compatibility with any aftermarket or original replacement strap.

For the Superocean A17366D71B2S1, the options most consistent with the model's instrumental character are: vegetable-tanned calf leather (develops patina over time), textured vulcanised rubber (water-resistant), matt alligator (for formal settings) and a double-layer nylon NATO strap (military-diving aesthetic). The choice depends on the intended context and desired colour pairing.

To replace the strap, remove the two spring bars connecting the strap to the case lugs. Use a dedicated forked spring bar tool, inserting the blade into the lug channel to compress the spring and release the bar. Care must be taken to avoid scratching the satin-finished steel. For NATO straps, the process is simpler: the spring bars can remain in place whilst the strap is threaded through.

Yes. Any strap with a 20mm lug width and an end profile compatible with the Superocean lug geometry is suitable as an aftermarket option. Milanostraps.it offers a curated selection of handcrafted 20mm straps in various materials and finishes, engineered for precise fit and long-term durability. All Casati Milano straps carry an 18-month production defect warranty.

The longevity of a leather strap depends on the type of leather, care routine and exposure to external agents. A quality calf leather strap worn daily and kept away from water typically shows visible wear after 12 to 24 months. Shell cordovan, owing to its dense and compact fibre structure, tends to last considerably longer. For a diver such as the Superocean, alternating with a rubber or NATO strap is advisable to extend the service life of the leather strap.
