Strap for Superocean Heritage 44 Chronograph Stainless Steel / Blue / Silver / Calf

The lug width of the Breitling Superocean Heritage A2337016.G753.433X is 22mm. This measurement is taken with a digital calliper at the internal gap between the two lugs at the lower end of the case. Any 22mm strap is compatible with this reference.

It depends on intended use. For sporting or marine environments, a vulcanised rubber strap or NATO nylon strap offers superior water resistance and durability. For business-casual wear, a vegetable-tanned calf leather or glossy alligator strap in 22mm provides character and longevity. In all cases, the 22mm lug width must be observed to ensure correct fitment within the case lugs.

The strap is removed using a springbar tool, inserting the lever tip into the small slots on the sides of the lugs. The spring bars compress and the strap slides free. The process is fully reversible and requires no watchmaking intervention. It is advisable to work on a soft surface to avoid scratching the case.

Yes. Any aftermarket strap with a 22mm lug width is compatible with this reference. Milanostraps.it offers a curated selection of Italian handcrafted straps — in alligator, calf leather, shell cordovan, NATO, and rubber — all available in 22mm. Standard 22mm spring bars are included or available separately.

On a sports-oriented diving watch, the lifespan of a leather strap depends heavily on actual use. Avoiding submersion and prolonged contact with salt water, a quality vegetable-tanned calf leather strap can last between 2 and 5 years with regular maintenance (conditioning with a neutral cream, rotation with other straps). For aquatic use, rubber or NATO straps remain the most practical choice. Casati Milano provides an 18-month guarantee against manufacturing defects on all handcrafted straps.
