The IWC Da Vinci Chronograph was introduced in 2007, as part of that years complete revamp of the Da Vinci collection. The round case was replaced for a tonneau-shaped one, available in a choice of metals and with a choice of movements and dials.The Da Vinci Chronograph is powered by the self-winding caliber 89360 with fly-back chronograph. Reference IW3764-17 was introduced in 2011, replacing the IW3764-10. The main difference is the strap.
