Strap for Superocean Heritage II Chronograph 44 Stainless Steel / Silver / NATO / Ocean Conservancy

The Breitling Superocean Heritage A133131A1G1W1 has a lug width of 22mm. This measurement should be taken with a digital calliper inside the lugs, at the point where they meet the case, to ensure correct compatibility with aftermarket straps.

The most suitable materials for the Superocean Heritage 44mm are vegetable-tanned Tuscan calf leather (for daily wear with natural patina development), alligator leather (for formal settings), vulcanised rubber (for sport and water use), and nylon NATO (for vintage pairings). The choice depends on intended use and dial colour: blue dials pair well with tobacco brown or midnight blue straps.

Strap replacement is carried out using the spring bars that connect the strap to the case lugs. A fork-style spring bar tool is required to release them carefully, avoiding scratches on the case. It is advisable to rest the watch on a soft cloth during the operation. If in doubt, a watchmaker or the Casati Milano atelier can perform the swap in just a few minutes.

Yes. Any strap with a 22mm attachment is compatible with the Breitling Superocean Heritage A133131A1G1W1, provided the spring bars are of the correct diameter (typically 1.8mm). Milano Straps offers a curated selection of handcrafted 22mm straps in various materials and finishes, available directly online.

The lifespan of a leather strap depends on the quality of the hide, the tanning method and the conditions of use. A high-quality vegetable-tanned Tuscan calf strap, properly maintained (avoiding prolonged water exposure and conditioning every 3–4 months), can last between 3 and 6 years while retaining a presentable appearance. Milano Straps provides an 18-month guarantee against manufacturing defects on all its straps.
