Strap for Vintage Aquatimer Automatic 1967 White Gold / White

The IWC Vintage Collection IW3231-10 features a lug width of 22mm. This measurement defines the distance between the two attachment pins (spring bars) on the case. You can verify this using a digital calliper or by consulting the original IWC documentation. Ensure any aftermarket strap is exactly 22mm wide to guarantee a secure, gapless fit without forcing the attachment points.

For a white gold 44mm case like the IW3231-10, we recommend alligator in cognac brown or black, vegetable-tanned calf in pearl grey, or shell cordovan in burgundy. Your choice should reflect intended use: alligator for formal occasions, calf for refined everyday wear, shell cordovan for depth and visual complexity. Ensure the strap is crafted from premium leather with a 22mm lug width for optimal compatibility.

Changing the strap requires a spring bar removal tool. Place your watch on a soft surface. Position the tool at the bottom of each spring bar and apply gentle pressure until the bar retracts slightly. You can then slide the strap out of the lugs. To install a new 22mm strap, insert the spring bar pins into the strap lug slots and push gently until you hear or feel a click confirming the bar has locked into position. If uncertain, consult a professional watchmaker.

Yes, absolutely. High-quality aftermarket straps are entirely compatible with the IWC Vintage Collection IW3231-10, provided they feature the correct 22mm lug width. Milano Straps offers an extensive selection of bespoke leather straps in alligator, calf, shell cordovan, and vulcanised rubber, all handcrafted and customisable in length, thread colour, and initials. An aftermarket strap can dramatically transform the aesthetic character of your timepiece.

Leather strap longevity depends on usage frequency, material type, and maintenance practices. Premium alligator or shell cordovan straps, used regularly but not daily, typically last 3–5 years. Vegetable-tanned calf, owing to its greater density, can endure 6–7 years. Moisture, perspiration, and sun exposure accelerate ageing. Protecting your strap with proper storage and occasional application of dedicated leather conditioner significantly extends its lifespan. Milano Straps straps include an 18-month manufacturing warranty.
