Going on a trans-Atlantic trip? 🛫Check out the Rolex GMT-Master Reference 6542, on offer at our #HongKong Important Watches Sale this October! . The 6542 was the first GMT-Master, and became the official timepieces of Pan-Am Airlines as its dual time was considered useful for trans-Atlantic travel. This example features a highly sought-after Bakelite bezel, and fetched a world record price of 260,000 Swiss Francs at our 2013 auction. Sotheby’s is delighted to present this watch again on 8 Oct, with an estimate of HK$1.6 – 2.4 m / US$204,000 – 306,000. . rolex #Sothebyswatches #Rolex #RolexGMT #RolexGMTMaster #Rolexwrist #Rolexwatches #Rolexlover #GMTMaster #WatchGeek #WatchesofInstagram
