IWC has released the second installment of its video series The Man’s Guide to Buying a Watch. The second part in the series focuses on what are known as complications. Complications are the additional features a timepiece offers aside from telling time. In the video IWC master watchmakers give us a bit of insight into certain complication such as the chronograph, minute repeater, perpetual calendar and tourbillon. Once again grab a pen and pad and take notes. Enjoy!
