The modest, modern design of the Tank Solo watch made it a classic from the moment it first appeared in the Tank collection. The Tank Solo honours the unique aesthetic that lies behind the collection's success while reworking the model with a number of variations, adding gold, steel, a rose dial, and a panther or python motif. These highly accessible variations were rapturously received. Case in 18K rose gold and steel, 18K rose gold beaded crown set with a synthetic spinel cabochon.
