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

The lug width of the Breitling Superocean Heritage AB2030161C1A1 is 22mm. This measurement is taken with a calliper placed inside the lugs at their narrowest point. Using the correct lug width is essential when sourcing compatible aftermarket straps to ensure a proper fit without play or tension.

The ideal choice depends on intended use. Vegetable-tanned calf leather develops a distinctive patina over time, complementing the vintage aesthetic of the model. Matte alligator is well-suited to smart-casual and formal occasions. Nylon NATO straps and vulcanised rubber are the most practical options for aquatic environments. All straps must measure 22mm at the lugs.

Strap replacement requires a fine-tipped spring bar tool. Insert the tip into the small slot on the lug, compress the spring bar inward, and slide the strap free. Care should be taken to avoid scratching the brushed stainless steel case. If in doubt, the operation is best entrusted to a watchmaker or a specialist atelier such as Casati Milano.

Yes, the 22mm format is widely supported by the aftermarket. Milano Straps offers handcrafted straps in leather, alligator, calf, and technical materials at 22mm lug width with a standard 20mm buckle taper. It is advisable to confirm the total strap length (short/long) based on wrist circumference and to check compatibility with standard 1.8mm spring bars.

The lifespan of a leather strap depends on tanning quality, water exposure, and daily care. A quality vegetable-tanned calf strap, kept away from water and conditioned periodically, typically lasts 2–4 years with regular wear. Alligator leather, due to the compact structure of its scales, generally offers greater longevity. Casati Milano provides an 18-month warranty against manufacturing defects.
