Strap for Superocean 42

The lug width of the Breitling Superocean A1736402BA29132S is 20 mm. This measurement is taken with a digital calliper positioned between the two lugs on the case back side. Any strap with a 20 mm attachment width is physically compatible with this reference.

The ideal choice depends on context. For formal settings, a glossy black or navy alligator strap complements the stainless steel case beautifully. For daily wear, vegetable-tanned calfskin develops an authentic patina over time. For marine or sporting use, vulcanised rubber is technically the most appropriate option: waterproof and resistant to salt. A ballistic nylon NATO strap suits a casual, adventure-ready aesthetic.

The strap is removed using a spring bar tool to compress the spring bars within the case lugs. The operation takes approximately two minutes and requires no professional equipment. It is advisable to work on a soft surface to avoid scratching the case or crystal. Alternatively, any watchmaker or jeweller can perform the swap in a matter of minutes.

Yes. Any strap with a 20 mm attachment width is physically compatible with the Breitling Superocean A1736402BA29132S. Milano Straps offers a curated selection of handcrafted straps in various leathers, rubber and nylon, all supplied with 20 mm spring bars included. The artisanal quality of Casati Milano straps is comparable — and frequently superior — to Breitling original accessories in terms of materials and finishing.

Longevity depends on the leather type, frequency of wear and maintenance. A good-quality calfskin strap, worn daily and kept away from excessive moisture and perspiration, typically lasts 2–4 years. Shell cordovan and quality alligator can exceed 5 years with minimal care (leather conditioner every 3–4 months). All Casati Milano straps carry an 18-month guarantee against manufacturing defects.
