The uncommon, very fine, and meticulously restored automatic IWC showcased in today's offering is 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 it "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."

The company built this watch in 1964 at the same they were building their famous Ingenieur line. Unlike most automatic IWC's from the era which almost always came in round cases, this is a much less common square cased automatic IWC.

While not a large watch at all, it wears just a bit larger than its dimensions.

It is fully IWC. All of its parts are original to the watch, and it has just finished a true expertly done restoration. It presents as mint.

The gloss black dial which presents with white Roman numerals has been meticulously refinished - the printing could pass as IWC factory done to the naked eye. The case presents as mint.

As part of the restoration, the movement has been freshly overhauled by a Master Watchmaker. It is running strongly and accurately.

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

As of this writing, we are listing a pair of these watches with black dials - this one with Roman markers and the other with steel batons.

A nearly sixty year old IWC that presents like new on the wrist!
