This 1934 Cartier 8-Day Tank Allongée may be a piece unique in white gold. It's certainly one of the most important Cartier wristwatches of its era. Only between 11 and 13 Cartier 8-day Tank Allongée are known to exist, with this example—starring in our upcoming Important Watches sale at #SothebysGeneva—the only one in white gold from the original series from the 1930’s. Take a closer look on Sothebys.com via the link in bio before the auction on 11 May. #SothebysWatches #Cartier
