In auction: pre-owned Rolex Submariner reference 16800. Its 40mm case has an unidirectional timing bezel with markings for the first fifteen minutes and five-minute hash marks through the 60. During time, the Rolex Submariner 16800 has become a cult favorite among today’s collectors, offering a number of unmistakably vintage design elements in a highly wearable package that is more than capable of standing up to everyday wear and use. The reference 16800 was also the first Submariner to offer water resistance up to 300 meters, which remains the Submariner’s standard depth rating to this day. Since the Submariner was initially developed for professional divers, it did not have a date mechanism on the dial during its early production years, as there was no need for a calendar display while diving anyway. However, Rolex eventually added it to the series in the late 1960s as its popularity among collectors of all lifestyles and professions took off. The Submariner also initially featured a bi-directional 60-minute bezel and an acrylic crystal. The Submariner really started to transform into what would become the ref. 16800 around the late 1950s when the ref. 5512 hit the market sporting, for the first time in Submariner history, crown guards and a larger 40mm case. About a decade later, Rolex released the first Submariner with a date mechanism on the dial and an accompanying Cyclops magnifier on the crystal with the launch of the ref. 1680. The ref. 16800 was its immediate successor.
