Rolex GMT-Master Ref. 1675: A Collector's Pair by the Ocean

The GMT-Master reference 1675 is a significant model in the brand's history, representing an evolution from earlier GMT-Master references. It was produced for an extended period, allowing for numerous dial, bezel, and hand variations throughout its production run. This reference is notable for its introduction of crown guards, enhancing the watch's robustness and contributing to its distinct profile. It solidified the GMT-Master's design language, which would influence subsequent generations.

This reference features a 40mm case, available in stainless steel, yellow gold, or a two-tone combination of steel and yellow gold. It is powered by the automatic Caliber 1575, a chronometer-certified movement known for its reliability and a power reserve of approximately 42 hours. The watch is fitted with an acrylic crystal and offers a water resistance of 50 meters, suitable for everyday wear. The bidirectional rotating bezel, typically with an aluminum insert, displays a 24-hour scale.

For collectors, the 1675 is highly sought after due to its long production period and the resulting variety of configurations, including different dial types (gilt, matte), hand styles, and bezel colors (Pepsi, all-red, all-black). Its four-digit reference number and acrylic crystal are key characteristics that define it as a vintage Rolex. The reference appeals to those interested in the historical development of the GMT-Master line and the nuances of vintage watch collecting.
