Strap for Superocean Heritage II 46 Chronograph Stainless Steel / Blue / Blue / Croco / Pin

The lug width on this model is 24mm, a common measurement for 46mm professional diving watches. To verify, measure the distance between the internal attachment lugs using a digital calliper, positioning the tip between the two metal pins. On this Heritage variant, the 24mm width ensures balanced proportions between case mass and strap, regardless of strap thickness.

The choice depends on your intended use: vegetable-tanned alligator for vintage formal aesthetics with evolving patina over time; chrome-tanned calfskin for a balance of durability and everyday wear; Croslite rubber for recreational diving and rapid drying; military-grade canvas for sporty character without maintenance demands. The deep blue dial pairs beautifully with cognac-brown alligator or satin black calfskin.

Use a spring bar removal tool. Position the flat end under the metal pin on the internal side of the case, apply steady, gentle pressure until the pin partially ejects. Grip it with fine tweezers and extract fully. Once removed, your old strap detaches. To fit the new strap, align its hole with the empty pin and insert it using the same controlled pressure, ensuring the strap sits properly between both case attachment points.

Absolutely. Any strap compatible with 24mm lugs will mount on the attachment rings. Ensure the thickness (1.2–1.6mm) permits smooth passage through the case channels without binding. High-quality artisanal straps from makers like Milano Straps feature precise tolerances and refined stitching that enhance the case's visual presence.

Lifespan varies with tanning method and usage. Vegetable-tanned alligator, kept dry between wears, lasts 3–5 years before reconditioning. Chrome-tanned calfskin resists ambient humidity better, lasting 4–6 years. Exposure to chlorine or seawater regularly degrades any natural leather within 2–3 years. Croslite rubber endures indefinitely with routine cleaning. Recommendation: alternate leather straps with rubber for diving to preserve aesthetics and extend longevity.
