IWC Yacht Club Ref.R811 Cal.8541 36.0mm 1970

The Yacht Club Ref.R811 balances elegance and strength through its rounded case, broad bezel and beautifully restrained silver sunburst dial. Polished baton hands and luminous markers add depth while preserving the watch’s composed sporting character. At its heart, the Cal.8541B delivers the silky Pellaton winding that defines one of IWC’s most admired vintage families.

In addition, this timepiece comes freshly serviced with all parts laid out by our professional watchmaker for all to see in the images above. Little to no other dealers do this and it’s a testament to full transparency here at Montre D’or. With the Cal.8541B inside running excellently as shown in the timegrapher reading above, just like it was when it left the factory nearly half a century ago.
