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

The lug width is 24mm. This measurement represents the space between the spring bars and is essential for selecting a compatible strap. We recommend verifying with a digital calliper, measuring both the inner and outer sides of the lug attachment to confirm accuracy before purchase.

For this 46mm model, authentic alligator (Mississippi or Nile) is recommended for elegant-sporty wear, or vegetable-tanned calf for those desiring progressive patina development. For professional diving environments or intensive daily use, an FKM (Viton) rubber strap offers maximum water resistance and durability. A technical nylon NATO is ideal for sporty and recreational iterations.

Minimal tools are required: a spring bar tool or a small flat-head screwdriver. Position the watch on a soft surface and insert the tool into the lateral groove of the spring bar, pushing gently downward. The bar retracts, freeing the strap. Repeat on the opposite side. Installing the new strap follows the reverse process: insert the bars into the lugs, ensuring they click fully into the locking slots.

A quality leather strap (alligator or calf) with daily use typically lasts 3-5 years before requiring replacement. Durability depends on humidity exposure, maintenance treatment and intensity of use. Vegetable-tanned straps develop patina and can extend their lifespan with regular cleaning and annual hydration. FKM (rubber) straps last 5-7 years under moderate use, extending to 10+ years with careful maintenance.
