Founded more than 150 years ago, the International Watch Company has become one of the most recognizable Swiss watch brands on the planet. One of the things they're especially famous for is their "Post-War" in-house movements, manual and automatic mechanical masterpieces which are long-time favorites among the watch community and IWC enthusiasts alike.

IWC’s Caliber 8531 is highly praised and regarded as one of the best automatic movements ever created. Featuring the Pellaton winding system which was a new and extremely efficient movement system for perpetual automatic wristwatch movements. This innovative movement was patented by IWC in 1950 and we saw the first mass production of these watches in 1952. The Pellaton winding system is still used in IWC watches today and has been improved upon ever since. Surrounding the heartbeat of this IWC ref. R347A is an absolutely beautiful and exceptionally well-preserved yellow gold Calatrava-style case and dial. It's as classic—and classy—as they come and would look good on any wrist, in pretty much any setting
