IWC INGENIEUR 3506 – GREY GRAPH PAPER DIAL – Gerald Genta – IWC Service Certificate – 1987

You like the 34 mm Ingenieur models with an integrated bracelet? – Great, you found the highly sought-after reference 3506 in all stainless steel with a captivating gray graph paper dial.

This is the second execution of the iconic Ingenieur model, which originated from the visionary mind of watch designing legend, Gerald Genta.

The soft yellow/red golden indexes and hands add a touch of opulence to the watch’s already luxurious appearance.

The bezel is an elusive centered one, as the “holes” were initially intended to be randomly aligned. To have it perfectly centered like this is a stroke of luck, making this timepiece even more desirable. The original bracelet has no stretch and can accommodate a good 19 cm wrist circumference.

With a Service guarantee certificate issued in 2002 by IWC Germany, owner’s manual, and service- and warranty booklets, you can rest easy knowing that this exquisite watch is in excellent condition.

Not only is it an excellent daily wearer, but it is also a solid investment that will stand the test of time. IWC is soon to launch its own vintage department and will sell vintage timepieces in their own stores. Can you guess which models will be the most famous ones?

Rest assured, like all our watches, this IWC comes with a 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.
