One on each wrist today. The Rolex was put back into service on March 11, set to my iPad at that time and worn 24/7. In this picture, it has lost 1.5 seconds in 26 days without stopping or having been re-set. My Speedmaster 345.0808 with the gold plated calibre 853 movement and sapphire back is the other. I conditioned it 16 months ago. It was set to my iPad 18-hours ago, and worn continually since then. It is one second fast to my iPad. This is one for Ripley!
