1974 IWC Vintage Mens Tonneau Watch, Caliber 423 - Stainless Steel


Item No. 6420

We are proud to offer today's this gorgeously restored IWC mens handwound watch.

For the movement the company used one of its superior high grade Caliber 423 handwound mechanisms with dual shock absorbers and micrometer regulator for precision adjustment.

Housing the fine movement is its classic original steel case done in a timeless tonneau style.

It is fully IWC down to the dial, hands, and winding crown. It has just finished a true expertly done restoration - it presents as about a 9.8 or 9.9 out of 10. Its royal blue dial has been meticulously refinished - its printing could pass as IWC factory done to the naked eye.

As part of the restoration it has just been fully serviced by a Master Watchmaker. The movement is quite pristine.

For the finishing touch it has been fitted with a new leather strap making it ready for immediate enjoyment.

Included with the purchase is a one-year warranty on the movement and its function, a custom printed Connoisseur of Time Certificate of Authenticity, and a new timing certificate attesting to its performance.

A four and a half decade old IWC that looks virtually like new!
