The Watch


The IWC Portugieser Rattrapante Ref. 3712, was first released in 1995 and would go on to serve as a great success for IWC, It has also been subject to a new modern re-issue. The 3712 was a split-seconds chronograph powered by Richard Habring's (at-the-time) new, accessible take on what is considered as one of the most complicated complications for Watchmakers to achieve.


A split-seconds chronograph allows you to record multiple intervals that start at the same time but don't end at the same time, for instance laps in a race. To achieve this, rattrapante chronographs come equipped with an additional seconds hand or rattrapante hand situated above or below the chronograph hand. As you engage the chronograph pusher, both hands move together. However, when you engage the rattrapante pusher, the rattrapante hand will stop.


This particular IWC Portugieser Rattrapante is in superb condition, it comes accompanied with its full set of Boxes and Paperwork and is completely original from when it was bought new in 2005.
