Strap for Vintage Aquatimer Automatic 1967 White Gold

The IWC Vintage Collection IW3231-04 features a lug width of 22 mm. This measurement is taken between the two spring bars protruding from the case and determines compatibility with aftermarket straps. milanostraps.it stocks a comprehensive collection of 22 mm straps ready for dispatch or bespoke customisation through the Casati Milano atelier.

For a timepiece of this calibre in white gold, we recommend refined leathers such as alligator, which complements the metal's nobility with natural texture and patina that develops authentically. Vegetable-tanned calf is an equally valid choice, offering suppleness and a subtler grain; shell cordovan appeals to those seeking chromatic depth and resilience. Synthetic materials should be avoided—white gold deserves authentic materials.

The process requires a spring bar tool. Place the watch on a soft cloth, gently push the lateral pin towards the case using the tool until the internal spring disengages, then remove the old strap. Insert the new strap ensuring the pin engages firmly in position. For precious metals such as white gold, professional assistance through the Casati Milano atelier is recommended.

Yes, provided it features a certified 22 mm lug width. The strap collection at milanostraps.it has been specifically curated for this watch category. Each strap is handcrafted with elevated finishes and can be personalised in length, leather selection, initials and thread colour to fit your wrist precisely.

Lifespan depends on usage intensity and maintenance. High-quality leather straps—such as those in alligator or shell cordovan from milanostraps.it—maintain full functionality between three and five years with daily wear. Natural leather develops a fascinating patina over time, shifting in colour and texture progressively. Casati Milano atelier provides an 18-month warranty on all bespoke straps and offers restoration and reconditioning services when required.
