IWC Calatrava Mid-Sized Jumbo R818AD C.8541B 35.0mm 1973

Up for sale here is a rare and classic IWC Calatrava reference R818AD from the 70s in a mid sized jumbo size of 35.0mm in diameter.

Starting with the dial, the dial comes flawless in a white that plays beautifully in the light with its sunburst effect. The dial comes with a beautiful set of pencil shaped mirror polished hands with black inserts that pair perfectly with the stick hour markers with similar black inserts.

Moving on to the case, the case comes in a beautiful mirror polish with little noticeable scratches. With a diameter of 35.0mm, it sits comfortably on the wrist with a slim presence. Perfect for sliding under the cuff of a dress shirt or for everyday use. At the 3 o’clock position sits the iconic fish logo crown, used to indicate its water resistance with the use of a rubber gasket compared to other non-fish logo IWCs.

Turning over to the case-back one would see a simple yet elegant brush and polish mix. Opening up the inside one would be able to see the beautiful C.8541B Automatic movement. Freshly serviced early January 2025, the movement runs at an excellent ~0s/day. Which for a watch of this age is extremely accurate and nearly on par with modern watches of today.

To top it all off the watch comes on a beautiful black crocodile leather strap with a aftermarket IWC signed stainless steel clasp.

As this watch is a vintage watch, we will not be able to guarantee its water resistance. Hence it is best to keep the watch away from any form of water and humidity, and store the watch with a dry tissue paper or silica gel packet nearby to draw moisture away from the watch. We will not be liable if any water damage is done to the watch after purchase.
