Strap for Superocean Heritage II 46 Chronograph Stainless Steel / Bronze / Bronze / Calf / Pin

The lug width of the Breitling Superocean Heritage A1331233/Q616/441X/A20BA.1 is 24mm. This is one of the widest lug widths in the sport diver segment and requires a native 24mm strap to ensure full lug coverage and eliminate lateral play between the strap and the case horns.

For the Superocean Heritage 46mm, the most suitable options are: vegetable-tanned calfskin for everyday wear with a natural developing patina, square-grain Mississippiensis alligator for a dress-sport profile, shell cordovan for those seeking long-term durability and a compact surface, and vulcanised rubber for marine use. In all cases, a steel deployant clasp is preferable to a standard buckle to distribute opening and closing stress across such a heavy case.

The strap is removed by inserting a flat-tipped spring bar tool into the springbar lug hole and applying gentle lever pressure until the bar releases. The springbars on the Superocean Heritage 46mm are 24mm and require a fine-tipped tool to avoid scratching the steel lug surfaces. The operation can be performed without professional tools, though care should be taken to avoid marking the case or the strap's end-piece.

Yes. Any strap with a 24mm attachment is technically compatible with the Breitling Superocean Heritage A1331233/Q616/441X/A20BA.1. Milano Straps offers a curated selection of handcrafted 24mm straps in various materials and finishes, available online or made to order at the Casati Milano atelier. It is also advisable to check the lug radius to ensure the strap curves correctly at the first few centimetres from the attachment point.

A quality leather strap — vegetable-tanned calfskin or alligator — on a diver like the Superocean Heritage has an average lifespan of 2–4 years with daily wear, depending on exposure to perspiration, water and UV light. The leather should be conditioned with a nourishing cream every 3–6 months and removed before diving or prolonged contact with salt water. A deployant clasp extends strap life by reducing bending cycles. Casati Milano provides an 18-month guarantee against manufacturing defects.
