Things you should know

This IWC Ingenieur Ref. 3508 is a superb specimen of the reference, boasting an unpolished case and bracelet that preserve its original sharp lines and classic profile. The case, which has remained crisp and robust, displays a few superficial scratches that affirm its authenticity and its careful use over time. The well-preserved bevels are especially noteworthy, retaining their prominence and sharpness—an essential characteristic of this model that enhances its appeal.

On the caseback, you'll find minor marks that are consistent with the watch’s enjoyment over the years, typical for a piece that has been appreciated rather than kept in a drawer. Importantly, the original serial engravings remain visible on the exterior of the caseback, a rare feature as these marks are often lost through regular wear.

The dial and hands are in exceptional condition, showcasing the gold-toned hands with well-preserved lume that beautifully complements the pristine white dial. The hands are free from oxidation, and the dial has retained its original crisp hue. All lume plots on the dial are in perfect condition and harmonize seamlessly with the lume on the hands.

The bracelet is another standout feature of this piece. With almost no stretch and minimal scratches, it maintains the structural integrity that speaks to the care it has received over the years.

Each component—the case, dial, and movement—bears IWC's signature, ensuring full authenticity. The crystal remains in near-perfect condition, free from noticeable scratches, preserving the clear view of this remarkable dial. Additionally, the watch is sold with an extra link.
