Pre-owned Navitimer B03 Chronograph Rattrapante 45 AB0310211Q1A1 (2017) takes one of the most iconic pilot’s watches ever made and pairs it with one of the most sophisticated chronograph complications in watchmaking. The Navitimer has been a favorite among aviators since the 1950s thanks to its signature slide rule bezel and incredibly functional design, but the example you see here adds an extra layer of mechanical intrigue that even seasoned collectors appreciate. The star of the show is the rattrapante, also known as a split-seconds chronograph. At first glance, the watch appears to have a standard chronograph, but a second chronograph hand is stacked beneath the first. When timing an event, the additional hand can be stopped independently to record an intermediate time while the main chronograph hand continues running. Press the pusher again, and the stopped hand instantly “catches up” to the running hand. This allows the wearer to time two events simultaneously or record split times during a race, making it one of the most useful and technically challenging chronograph complications to produce.
