One year after the introduction of the new style GMT-Master II Reference 116718, rolex expanded the collection with three gem-set variations: the 116718 SA, SANR and the present SARU. This GMT-Master II, ref. 116758SARU, has a 24-hour revolving bezel which is enhanced with baguette-cut sapphires, rubies and diamonds, and a diamond-set case. A highlight of the Important Watches auction on 10 May. Photo by our specialist m_a_n_e_g_a #SothebysWatches #SothebysGeneva #LuxuryWeek #Rolex
