The Vintage Collection IW3231-05 (aka: 3231-05, IW323105), seen from the bench

The IWC Vintage Collection IW3231-05 is a reinterpretation of 20th-century military chronographs, featuring a 44mm platinum case and IWC caliber 80111 movement displaying hours, minutes, seconds, and date. The 22mm lug width is proportioned to balance the case diameter, ensuring stable wear and minimal play on the strap. Platinum's noble character absorbs and returns light with a sobriety steel cannot match, developing a unique patina over time.

Frequently asked questions

What is the lug width of the IWC Vintage Collection IW3231-05?

The lug width of the IWC Vintage Collection IW3231-05 is 22mm. This dimension was deliberately calibrated by IWC to balance the proportions of the 44mm platinum case, ensuring secure wear and ease of strap changes.

Which strap is best suited to the IWC Vintage Collection IW3231-05?

An alligator strap with vegetable tanning represents the most elegant choice, complementing the nobility of the platinum case. Alternatively, shell cordovan offers tactile substance and a naturally evolving patina. For contemporary versatility, a NATO strap with a polished steel deployant transforms the timepiece into a more dynamic instrument.

How do I change the strap on the IWC Vintage Collection IW3231-05?

Use a spring bar tool to gently remove the elastic pins from the lugs. Position the tool in the spring tension slot, press downward and simultaneously slide the lug outward. For installation, insert the new strap into the lugs and, using the tool, push the elastic pin downward until it fully engages. Verify that the strap is properly seated before wearing.

Is a 22mm aftermarket strap compatible with the IWC Vintage Collection IW3231-05?

Yes, any strap with a 22mm lug width is compatible with the IW3231-05. Milano Straps' customizable straps offer the choice of premium materials, custom lengths, and details such as embroidered initials or bespoke stitching thread, guaranteeing perfect fit on your case.

How long does a leather strap last on the IWC Vintage Collection IW3231-05?

An alligator or shell cordovan strap with vegetable tanning, when worn regularly, retains full functionality for 3-5 years. Longevity depends on frequency of use, sun exposure, and humidity levels. Calf leather, being more delicate, may benefit from rotation with other straps to extend its lifespan. Milano Straps provides an 18-month warranty on all bespoke straps.
