Strap for Superocean Heritage II B20 Automatic 44 Stainless Steel / Black / Bracelet

The lug width of the Breitling Superocean Heritage AB2030121B1A1 is 22mm. This measurement is taken internally between the two case lugs using a calliper or a millimetre ruler, positioned at the base of the lug. It is the standard dimension adopted by Breitling across the entire Superocean 44mm range.

The ideal choice depends on intended use and aesthetic preference. For formal or smart-casual settings, an alligator strap with a polished grain or a Tuscan vegetable-tanned calf leather strap best complements the model's dual sporting-elegant character. For aquatic or active use, vulcanised rubber or ballistic nylon NATO straps are technically coherent options. A brushed steel deployant clasp completes any high-end pairing.

The strap is replaced by acting on the spring bars connecting the bracelet or strap to the case lugs. Insert the tip of a springbar tool into the small hole on the side of the lug to compress the spring bar and release it. The operation takes approximately two minutes per side and does not require a watchmaker, provided you work on a soft surface to avoid scratching the case.

Yes. Any strap with a 22mm lug width and standard profile is compatible with the Breitling Superocean Heritage AB2030121B1A1. Milano Straps offers a curated selection of handcrafted 22mm straps in various materials — leather, alligator, rubber, NATO — produced with finishing and stitching comparable to the original, and often superior in terms of personalisation and leather selection.

The lifespan of a leather strap depends on the quality of the tanning process, the thickness of the hide, and daily use. A quality vegetable-tanned calf strap, used with care and kept away from prolonged water or perspiration exposure, can last between 3 and 5 years while retaining its structural and aesthetic integrity. A high-grade alligator strap, owing to the natural density of the scales, can exceed 5 to 7 years. Proper storage in a dry environment and the use of dedicated conditioning creams significantly extend strap life.
