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 85x 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 case of this watch in c. 1974 at the same they were building their famous Ingenieur line and with equipped it with the same movement. 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.

At 36mm in diameter, it is the same size as a Rolex Datejust.

It is in beautiful original condition. The untouched dial is mint. It doesn't seem to appear to have been polished, or if so very lightly.

The parts are 100% original as it left the factory.

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.
