IWC Ingenieur 3506 grey graph paper dial – IWC Service – Gerald Genta – 1985/86

Pobably the most sought after reference of the 34mm version of the early Ingenieur models with integrated bracelet.

The reference 3506 in all stainless steel and grey graph paper dial.

Beautiful overall condition.

Recently serviced by an IWC Service center in Germany.

You will have noticed that we have a strong link to IWC and especially the Ingenieur models.

For us, this version is one of the most beautiful ones, we ever had.

Not as rare as the 3505 we also offer HERE – but second to this, it is our favourite version.

It’s the second execution of the 34mm Ingenieur model based on Gerald Genta’s famous design (Ingenier, Ref. 1832) from about 1985/86.

The soft yellow/red golden indexes and hands complete the overall luxury look of this fine timepiece.

The dial is flawless!

Case has some very minor signs of wear, nothing serious.

To those who haven’t noticed it yet, the bezel is a rare centered one! The “holes” were intended to be random in alignmen, to have it centered like this is just a matter of luck with this bezel.

The original bracelet has no stretch and will fit up to about 18.5cm wrist circumference.

Comes with the IWC Service-Center service report plus invoice and an IWC Service-Box.

Its a great daily beater and for sure a very good investement!
