IWC Portugieser Yacht Club Chronograph IW3905

The IWC Yacht Club was a three-hander watch until 2010, when the Portugieser Yacht Club Chronograph was presented. The 2015 version has been modified to a degree, above all in some design touches. Most importantly, the case diameter has been reduced from 45.4 to 43.5 millimetres. It is intended as a watch for yachtsmen and so the case is water-resistance-rated at 60 metres depth, and it is mounted on a rubber strap. The chronograph, with a red seconds hand read off a quarter-second scale, is perfect for timing short intervals such as the seconds between a signal and the start of a regatta. It is equally good for keeping track of long elapsed times, because the minutes and hours are shown on the top subdial, in an easy-to-read analogue layout. The chronograph has the flyback function.

The 89361-calibre automatic movement is made in-house, and runs at 28,800 vph/4 Hertz. It has a power reserve of 68 hours. The movement can be viewed through the sapphire caseback.
