Today's offering showcases this superior automatic IWC powered by the Albert Pellaton designed Caliber 8541 movement. 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 85 series "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 the movement of this watch in 1966 at the same they were building their famous Ingenieur line. These dress watches are more elegant than the pragmatic Ingenieur but share similar 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.

It is in beautiful original condition. The untouched dial is mint.

It is fully IWC down to the original fish signed crown.

And the movement has been freshly overhauled and is running very true.

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.
