Strap for Superocean Heritage II B20 Automatic 42 Stainless Steel / Red Gold / Black / Bracelet

The lug width of the Breitling Superocean Heritage UB2010121B1A1 is 22 mm. This is a standard measurement for this Breitling family and determines the exact strap size required. Before purchasing an aftermarket strap, it is advisable to verify the measurement using a digital calliper placed between the case lugs.

For the UB2010121B1A1 variant in steel, 18k red gold and black ceramic, the most suitable straps are alligator with hornback grain in dark brown, cognac or midnight blue — which complement the red gold accents — or vegetable-tanned calfskin for everyday wear with a developing patina. For marine or sporting use, a vulcanised rubber strap in 22 mm is the most functionally coherent choice for a diver of this calibre.

Strap replacement on the Superocean Heritage UB2010121B1A1 is performed using standard spring bars. A springbar tool — or a thin flat-tipped blade — is required to compress the spring bar ends and release them from the case lugs. The operation does not require a watchmaker and can be completed in a few minutes with the correct equipment, taking care not to scratch the ceramic bezel.

Yes, any strap with a 22 mm lug width and standard spring bars is technically compatible with the Breitling Superocean Heritage UB2010121B1A1. Milano Straps offers a curated selection of handcrafted 22 mm straps in alligator, vegetable-tanned calfskin, shell cordovan, rubber and NATO nylon, all manufactured to precise fitting tolerances for an optimal mount without modification to the original case.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear and exposure to perspiration and moisture. A high-quality alligator or vegetable-tanned calfskin strap, with regular use and minimal care (conditioning cream every 2–3 months, storage away from heat sources), can last between 3 and 6 years whilst maintaining good structural integrity. Shell cordovan straps, owing to the density of the fibre, typically offer above-average longevity.
