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

The lug width of this model is 24mm, measured from the innermost point of one lug to the innermost point of the opposite lug, perpendicular to the case. This is an oversized specification requiring bespoke, artisanal strap construction.

Selection depends on use case and aesthetic preference. Vegetable-tanned alligator delivers refinement and striking contrast with the brushed steel case. Aged calf leather offers softness and natural patina development. Treated rubber is unmatched in humid environments. Shell cordovan represents the choice for those seeking multi-decade durability and progressive lustre.

Use a spring bar remover to compress the metal springs attached to the lugs and extract the current strap. Insert the remover's tips into the lateral slots, gently push inward whilst simultaneously withdrawing the bar. Exercise care to avoid scratching the case. Repeat on the opposite side. Insert the new strap, ensuring proper alignment with the case lugs.

Yes, provided the lug width is precisely 24mm. Bespoke leather and rubber straps constructed to this specification offer guaranteed compatibility. Always verify that the strap features identical width and that the spring bars are correctly dimensioned for the case lugs.

Longevity depends on material grade and environmental conditions. Quality vegetable-tanned alligator or calf, worn daily, maintains structural integrity between 3 and 5 years. Shell cordovan easily exceeds 5-7 years due to leather density and inherent resistance. Humid environments, frequent perspiration and absent maintenance reduce lifespan. Rotating between multiple straps significantly extends the life of each.
