Strap for Superocean Heritage II B01 Chronograph 44 Stainless Steel / Blue / Rubber / Folding

The lug width of the Breitling Superocean Heritage AB0162161C1S1 is 22mm. This measurement is taken with a digital calliper inside the spring bar seat, between the two lugs of the case, and represents the standard size for replacing the strap with any compatible aftermarket option.

It depends on the intended use. For formal occasions, a Hornback alligator strap in a matte finish or a shell cordovan strap best complements the vintage aesthetic of the model. For everyday wear, Tuscan vegetable-tanned calf leather develops an authentic patina over time. For sporting or marine use, vulcanised rubber with micro-perforations is the most appropriate choice given the Superocean Heritage's diving vocation.

The strap is removed using a spring bar tool or a fine-tipped lever screwdriver inserted into the slot on the side of the lug. It is advisable to work on a soft surface to avoid scratching the case. Breitling's original spring bars have a diameter of 1.8mm: when replacing them, verify the diameter compatibility to prevent unwanted play within the lug.

Yes. Any strap with a lug width of 22mm and a standard taper to 20mm at the buckle end is physically compatible. Milanostraps.it offers a selection of handcrafted straps in the 22mm size made specifically for this lug spacing, available in various leather options, stitching styles and buckle choices — including a deployant clasp — suited to the curved case of the Superocean Heritage.

Longevity depends on the material and exposure to water. A shell cordovan or vegetable-tanned calf strap treated with natural waxes can last 3 to 5 years with routine care, provided prolonged immersion is avoided. For frequent water use, a rubber or technical nylon NATO strap is preferable. Casati Milano offers an 18-month guarantee against manufacturing defects on all handcrafted straps.
