Vintage Hour: Rolex GMT Master Ref 1675

One of the longest running and most recognizable Rolex watches is the GMT Master with Reference 1675. Produced between 1959 and 1980, the GMT Master 1675 enjoy one of the longest production runs in Rolex history. Though a vintage watch, the GMT Master is not a hard Rolex watch to find simply because it was produced for such a long time and there is more product. Despite this there are versions of the 1675 that are more rare and valuable, especially among the early models.

There are several key identifiers that help dealers date the GMT Master 1675. For example, earlier models featured pointed crown guards as well as a chapter ring. The very earliest Rolex GMT Masters were produced with a Bakelite bezel. However, ref 1675 has always had a metal bezel for sturdiness and stability so this does not help date it. During the first ten years of production the Rolex GMT Master 1675 featured a small triangle on the extra hour hand. This was later replaced by a red hand with a larger triangle in the 1970s. This simple change is one of the easiest identifying points in helping to date examples of the GMT Master 1675 during its long production run.

Earl 1675 versions also feature gilt dial printing on the outer ring around the hour and minute markers. Later, after the larger triangle on the 24-hour hand was introduced, the printing on the dial changed. In 1965 it had completely changed to all-white dial printing from the gilt printing, and by 1967 the outer ring had been completely removed. The pointed crown guards were also replaced with rounded ones. These identifying markers make it easier to date a ref 1675.

The GMT Master 1675’s bezel is its most recognizable feature. The red and blue bezel has been nicknamed the “Pepsi” bezel, and is highly sought after by collectors. In 1972 the bezel became available in all black, offering more option.

The watch’s caliber also changed during production. The original 1675 features caliber 1565 from 1959 to 1964. From 1965 to 1980 the watch featured caliber 1575. As with most Rolex watches, the GMT Master 1675 offers a water proof oyster case that can withstand water pressure up to 50 meters (165 feet). The Rolex GMT Master was also the first Rolex sports watch to feature both the Oyster and Jubilee bracelet styles.

The GMT Master is one of the most recognizable Rolex watches, but it is also fairly easy to find and add to your collection. If you want a beautiful, popular and unique piece, the Rolex GMT Master 1675 is the watch for you.
