Strap for Superocean Heritage II B20 Automatic 44 Stainless Steel / Red Gold / Black / Milanese

The lug width of the Breitling Superocean Heritage UB2030121B1A1 is 22mm. This measurement is taken with a digital calliper across the internal gap between the lugs, at the point where the strap slides beneath the case. It is one of the most common standard sizes in high-end sports watchmaking.

For the Superocean Heritage UB2030121B1A1, with its case combining stainless steel, ceramic and red gold, the most coherent options are vegetable-tanned calf leather in havana or cognac tones, lacquered alligator in bordeaux or midnight blue, and vulcanised rubber for marine use. A deployant clasp in steel or red gold completes any leather pairing while improving comfort and longevity.

The strap is removed using a springbar tool — a bifurcated-tip instrument that compresses the spring bars fitted within the 22mm lugs. The operation takes approximately two minutes and requires no specialist watchmaking assistance. Place the watch face-down on a soft cloth to prevent scratching the case or ceramic surfaces.

Yes. Any aftermarket strap with a straight 22mm end is compatible with the Superocean Heritage UB2030121B1A1. On milanostraps.it you will find handcrafted straps in vegetable-tanned leather, alligator, shell cordovan and technical rubber, all fitted with standard 22mm spring bars and buckles or deployant clasps in brushed stainless steel or PVD.

A quality leather strap exposed regularly to salt water, humidity and sea air will typically show signs of structural degradation within 12 to 18 months. For frequent marine use, vulcanised rubber or technical nylon NATO straps are strongly recommended. Even treated leather is not designed for immersion or prolonged exposure to salt water.
