IWC IW3766-02 description
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 a self-winding caliber with fly-back chronograph. Reference IW3766-01 is an uncommon version with ceramic / titanium case. It was available from ca. 2010 to 2012. The difference between that and the present -02 are not known to us at the moment.
