Strap for Superocean 42 Stainless Steel / Black / Rubber / Pin

The Breitling Superocean A17366021B1S1 features a 20mm lug width. This measurement can be verified directly on the case using a millimetre calliper, measuring the internal distance between the two lugs. Any strap with a 20mm attachment is compatible with this reference.

The ideal choice depends on the intended use. For formal or business-casual wear, a matte alligator strap in 20mm complements the stainless steel case without overpowering the dial. For sporting or marine use, vulcanised rubber or ballistic nylon NATO straps are technically more suitable, offering water resistance and durability under intensive use.

Strap replacement is carried out by removing the two springbars securing the original strap to the lugs. A forked-tip springbar tool is sufficient to lever each springbar and release it. It is advisable to work on a soft surface to avoid scratching the case. The new 20mm strap is fitted by engaging one springbar first, then the other.

Yes. Any aftermarket strap with a 20mm attachment is compatible with the Breitling Superocean A17366021B1S1, provided the springbars have the correct diameter for the lugs of this model. Milanostraps.it offers a curated selection of artisan straps in various leathers and technical materials, all produced for this specific lug width.

Longevity depends on the leather type, frequency of wear, and exposure to perspiration and moisture. A vegetable-tanned calfskin strap, properly maintained with protective wax, typically lasts 2 to 4 years with daily wear. Alligator leather, owing to its dense scale structure, is more resilient and may exceed 5 years. Technical rubber is unaffected by moisture but may harden over time due to UV exposure.
