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

The lug width is 24mm. This measurement defines the space between the case lugs and determines which straps are compatible with the model. Always verify this dimension with callipers before ordering an aftermarket strap.

The ideal strap depends on intended use: for formal elegance, black alligator or vegetable-tanned leather in brown tones; for aquatic environments, blue FKM rubber; for daily versatility, grey or blue fabric NATO. The 46mm case proportions require robust straps with visual balance.

Use a spring bar tool to gently compress the lugs, lift the old strap and remove it. Position the new strap by aligning the two holes with the lugs, then allow the lugs to snap into place. If the strap has a deployante, verify that the mechanism is correctly engaged to the case.

Yes, any strap with 24mm lug width is compatible. Milano Straps offers artisanal leather straps, Tuscan leather, alligator and FKM rubber specifically sized for this reference, with custom tailoring options at the Casati Milano atelier.

A quality strap with vegetable tanning has a lifespan of 3-5 years with daily wear, depending on exposure to moisture and sunlight. FKM rubber, more resistant to marine environments, maintains structural integrity for 5-7 years. A natural alligator strap, if properly cared for, ages elegantly without significant deterioration.
