Vacheron Constantin Traditionnelle Tourbillon Retrograde Date Openface

The Traditionnelle Tourbillon Retrograde Date Openface watch is powered by the self-winding Calibre 2162 R31/270, a 242-component manufacture movement with a 72-hour power reserve. Operating at a rate of 18,000 vibrations per hour and measuring just 6.35 mm thick thanks to its peripheral gold oscillating weight, it combines a tourbillon at 6 o'clock with a retrograde date whose intricate workings can be seen through the upper part of the openworked dial.
