IWC Ingenieur SL Automatic Grey Graph Paper Dial REF: 3506 – ca. 1985

The IWC Ingenieur line with integrated steel bracelet has experienced a real upswing in the last two years. In particular, the SL automatic versions with a graph paper dial are in high demand among collectors.
Appreciation for Mixte models has also finally returned to the market. Not without reason! Gold is always in fashion, especially when combined with the cool hue of stainless steel, watches in steel/gold exude an unmistakable vintage look.

This 34 mm version of the Gerald Genta classic captivates with the timeless elegance of its design. This watch is predicted to have a similarly exciting future as the AP Royal Oak a few years ago. The demand for sporty classics in medium-size is unbroken and continues to rise.

A few small spots on the dial, bracelet has some stretch. Case, bracelet and hands are in pleasing visual condition but have some patina as well.

The watch fits up to a wrist circumference of approximately 18.5/19cm.

Definitely a good investment for the future or just a nice watch to wear and look at.
