Strap for Vintage Aquatimer Automatic 1967 Stainless Steel

The lug width of the IWC Vintage Collection IW3231-01 is 22 mm. This measurement represents the distance between the spring bars that attach the strap to the case lugs. Always verify this specification before purchasing an aftermarket strap, as even minor variations can result in incompatibility.

For the IWC Vintage Collection IW3231-01, we recommend a vegetable-tanned leather strap to maintain the model's historical character. A tobacco brown or deep black creates balanced harmonious pairing with the stainless steel case. If you prefer greater structural durability, alligator leather with boned texture enhances the technical character of the watch without compromising original aesthetics.

Strap replacement requires a dedicated spring bar tool to remove the retaining pins from the case lugs. Position the tool beneath the pin and apply gentle upward pressure to release the internal spring, then extract the pin. Repeat on the opposite side. For installation, align the strap holes with the lugs and reinsert the pins, ensuring they are firmly secured in their final positions.

A quality vegetable-tanned leather strap typically lasts 3–5 years with moderate daily use. Longevity depends on intensity of wear, climatic conditions, and maintenance practices. Alligator or shell cordovan straps tend to offer longer service life due to the fibrous structure of the material. The natural patina developing over time indicates aesthetic evolution rather than deterioration.
