Strap for Superocean Heritage II B20 Automatic 44 Stainless Steel / Greece

The Breitling Superocean Heritage AB20303A1A1A1 features a lug width of 22mm. This measurement is taken with a digital calliper placed between the lugs at the spring bar seat. 22mm is a widely adopted standard in high-end sport watchmaking, ensuring broad compatibility with aftermarket straps without the need for adapters.

The choice depends on intended use. For a sport-elegant context, vegetable-tanned calfskin with a natural grain is the most versatile option, developing a distinctive patina over time. For formal occasions, black or midnight blue lacquered alligator enhances the ceramic bezel. For marine use, a nylon NATO or vulcanised rubber strap provides water resistance and practicality. A brushed steel deployant clasp distributes tension evenly, extending the service life of leather straps.

Strap replacement is carried out via the standard 22mm spring bars housed between the lugs. Using a fine-tipped spring bar tool, compress the spring bar to release it from the lug, remove the strap, and insert the new one. No professional tools are required, though it is advisable to work on a soft surface to avoid scratching the steel case or ceramic bezel. If in doubt, any watchmaker can perform the swap in minutes.

Yes. Any strap with a 22mm lug width is compatible with the Breitling Superocean Heritage 44. High-quality handcrafted aftermarket straps — such as those produced by Casati Milano — use the same standard spring bars and ensure a precise fit. It is important to verify that the strap end does not exceed 22mm in width and that its thickness is compatible with the lug gap.

Longevity depends on leather quality, tanning method, and daily use. A high-grade vegetable-tanned calfskin strap, with regular but non-intensive wear, retains its structural and aesthetic integrity for 2 to 4 years. Alligator, due to the natural density of its scales, tends to last longer if kept away from excessive perspiration and prolonged moisture. Shell cordovan straps can exceed 5 years with proper care. Casati Milano provides an 18-month warranty against manufacturing defects on all handcrafted straps.
