Strap for Superocean Heritage II 46 Stainless Steel / Bronze / Bronze / Milanese

The lug width is 24 millimetres, a dimension that requires specifically sized straps. This measurement refers to the space between the lugs of the case, expressed in millimetres. You can verify it by measuring directly with a calliper the distance between the spring bar attachment points, or by checking the number marked on the base of the current strap.

The choice depends on the intended use. For formal elegance, we recommend alligator in black or brown with vegetable tanning. For everyday versatility, a NATO strap in canvas or a technical FKM rubber strap keeps the watch in its native diving element. Horween shell cordovan in wine or cognac tones offers a sophisticated compromise between aesthetics and durability.

Obtain a spring bar tool and position it under the spring bar attachment from the inside. Apply light pressure to compress the internal spring, allowing extraction from the seat. Repeat on the other side. To install the new strap, align the lug holes with the spring bars and press until the locking click is felt, ensuring the strap is firmly secured.

Only with models featuring the same 24-millimetre lug width. Many modern sports watches use different standards (20, 22 or 26 millimetres). Before purchasing an aftermarket strap, always verify the lug width of your watch to avoid incompatibility.

A quality leather strap, made from materials such as alligator or Horween shell cordovan with vegetable tanning, has a lifespan of 3–5 years with regular wear and proper maintenance. Durability depends on frequency of use, exposure to moisture, and quality of craftsmanship. Artisanal straps from Casati Milano benefit from an 18-month warranty and can be restored through re-stitching and leather reconditioning.
