The superior automatic IWC showcased in today's offering is a rare example encased in platinum and powered by the Albert Pellaton designed Caliber 852 movement. It was made for the Japanese market by Isomura, and unlike some examples it is triple-signed IWC.

This mechanism's automatic winding system is a technical masterpiece, earning it high praise - Gisbert Brunner and Christian Pfeiffer-Belli in their work, Wristwatches Armbanduhren Montres-bracelets, proclaimed the 85x "one of the best automatic movements ever built in Switzerland."

And the famous watchmaker Donald de Carle, in his book Complicated Watches and their Repair, stated that IWC's special automatic winding mechanism was "a simple and ingenious system, well constructed and beautifully finished."

IWC built it in 1958 at the same time they were building their famous Ingenieur line. These dress watches were more elegant than the pragmatic Ingenieur but shared the high-performance timekeeping qualities in normal wearing conditions. And compared to an Ingenieur, because they do not have a second inner back, the cases are thinner and lighter on the wrist.

While the vast majority of these were made in stainless steel with some also being made in 18K gold and a few gold plated cases, only very few were ever made in platinum.

We have owned a number of these rare platinum cased IWC's over the last several years, and the case on this one is unlike any other that we have seen. Its lug design is fascinating. They seem slightly curved in two directions, almost like the case design of a Frank Muller Cintree.

It measures approximately 35mm in diameter, in between the sizes of a Rolex Date and a Rolex Datejust.

It is fully IWC down to the dial and all hands. It has just finished a true expertly done restoration and presents in gorgeous condition. Our pictures couldn't begin to do it justice!

Its rare platinum case presents as mint. Its gloss black dial has been meticulously restored - its printing could pass as IWC factory done to the naked eye.

Note that the back was not fully snapped on and not straight when the photos were taken. It has since been aligned and secured.

As part of the restoration, a Master Watchmaker has freshly overhauled the movement which winds smoothly. It is running strong and true, keeping time essentially on par with a brand new IWC.

Photos of the inside available upon request.

For the finishing touch, we have equipped it with a brand new calfskin 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.
