Strap for Superocean 42

The lug width of the Breitling Superocean A1736402BA30131A is 20 mm. This measurement is taken with a calliper at the point where the case lugs meet the strap attachment, and is the correct standard for selecting any compatible aftermarket strap for this reference.

The ideal strap for the Superocean 42mm depends on the occasion. An alligator leather strap suits formal settings, while vegetable-tanned calf leather develops a natural patina over time, making it excellent for everyday wear. Vulcanised rubber is recommended for sport or humid environments, whilst a ballistic nylon NATO adds authentic tool-watch character and quick-change practicality.

Strap replacement requires a spring bar tool to remove the 20 mm spring bars from the case lugs. Proceed carefully to avoid scratching the stainless steel case. It is advisable to use a soft cloth as protection between the tool and the case, or to entrust the operation to a qualified watchmaker.

Yes. The 20 mm lug width is one of the most common standards in the industry, so the aftermarket offers an extensive range of compatible straps. Milano Straps provides handcrafted straps in alligator, calf leather, shell cordovan, rubber, and NATO weaves, all with a 20 mm attachment, available bespoke or ready to ship online.

The lifespan of a leather strap depends on leather quality, frequency of use, and maintenance. A high-quality strap in vegetable-tanned calf or alligator can last between 2 and 5 years with proper care. Avoid prolonged exposure to water and perspiration, do not wear it during water activities, and apply a quality leather conditioner periodically.
