IWC INGENIEUR 3506 – BLACK GRAPH PAPER DIAL – IWC Serviced – Gerald Genta – 1986

Are you interested in the 34mm Ingenieur models that come with an integrated bracelet? If so, then you’ve found the highly sought-after reference 3506. This stainless steel version features a captivating black graph paper dial. This particular model is the second execution of the iconic Ingenieur design, which was originally created by the visionary watch designer Gerald Genta.

The watch boasts soft yellow and red golden indexes and hands, adding a touch of opulence to its already luxurious appearance. The bezel is centered, which is a rare find as the “holes” were initially meant to be randomly aligned. This feature makes this timepiece even more desirable. The original bracelet has no stretch and can fit a wrist circumference of up to 19cm.

This exquisite watch was serviced at IWC headquarters in Switzerland (November 2022) and comes with a Service Guarantee certificate that was issued in November 2022 by IWC. The watch is still under IWC official warranty.

You can rest easy knowing that this watch is in excellent condition. Not only is it an excellent daily wearer, but it’s also a solid investment that will stand the test of time. IWC is launching its own vintage department and will soon sell vintage timepieces in their own stores. Can you guess which models will be the most famous ones?

As with all of our watches, this IWC comes with our full 24-month warranty, ensuring your peace of mind. The IWC caliber 3752, with its solid 21k gold rotor, is the perfect finishing touch to this stunning watch.
