Rolex 16718 (Usato - Eccellente) — USD 2,330 on eBay

The GMT-Master II reference 16718 represents a full yellow gold execution within the second generation of Rolex's dual time zone professional watch. Introduced as part of the updated GMT-Master II line, it offered the enhanced functionality of an independently adjustable 12-hour hand, allowing for quick setting of local time without disturbing the 24-hour GMT hand or the running of the watch. This reference was available with various bezel insert colors, including the black aluminum insert, and different dial configurations, catering to a discerning clientele seeking a robust yet luxurious travel timepiece. This reference features a 40 mm Oyster case crafted from 18ct yellow gold, providing substantial presence and durability. It is fitted with a sapphire crystal and is water-resistant to 100 meters. The watch is powered by the automatic caliber 3175, a chronometer-certified movement known for its precision and reliability, offering a power reserve of approximately 48 hours. The bidirectional rotating bezel, with its 24-hour scale, facilitates the tracking of a third time zone when used in conjunction with the GMT hand. For collectors, the 16718 is significant as a solid gold variant of the GMT-Master II, bridging the gap between tool watch utility and precious metal luxury. Its production run saw the transition through different dial types, including tritium and later luminova, which are points of interest for collectors. The availability of different bezel colors, such as the black insert, also adds to its collectibility, allowing for personalization and offering distinct aesthetic variations within the reference.
