Today's offering showcases this superior automatic IWC powered by the Albert Pellaton designed Caliber 8541 movement and with elegant 18K case with lobed lugs.

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 this watch in 1964 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 35mm in diameter, it is in between the sizes of a Rolex Date and a Rolex Datejust.

It is in beautiful original condition, fully original down to the dial, hands, and original fish signed crown. The untouched dial is just short of mint. A Master Watchmaker has just serviced the watch (a $595 value).

For the finishing touch we have installed a new crocodile strap.

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.
