Case and Strap

It has 22 jewels, beats at a frequency of 28,800 vph or 4 Hz and has a power reserve of 3.5 days or 84 hours. The high-power reserve is a result of IWC’s Diamond Shell® technology, that “reduces friction and improves the flow of energy in the movement.”  The calibre features an integrated tourbillon stop. When the crown is pulled out, the tourbillon mechanism stops, and the timepiece can be set with “down-to-the-second accuracy.” It features movement finishing such as circular Geneva stripes and gold-plated components.
