How is the Rolex GMT Different in the Rolex Submariner?
Rolex created these two versions to satisfy different professional needs. A number of the major aspects where the watch versions differ from each other are clarified below:
1. The Rolex Submariner features a uni-directional rotating bezel rather than this bi-directional bezel found from the Rolex GMT watches. The functionality of the bezels differs in both versions. The uni-directional bezel in the Rolex Submariner is intended to enable a diver measure the elapsed time while diving. Before a diver gets enters the water, then he needs to place the bezel so the triangle engraved on the bezel points at the present minute hand position. This will begin counting the minutes while the diver descends. Likewise by resetting the job of the triangle, he can pace his ascent as well.
Therefore, by measuring the elapsed time, the bezel ensures that the safety of the diver. (On the flip side, the bi-directional rotating bezel in the Rolex GMT assists the wearer to read the time in two time zones simultaneously. Divided into two equal portions, the time 6:00 to 18:00 represents the day and the time 18:00 to 6:00 represents the night. The specific 24 hour hand is used to display the 24 hour timeframe on the bezel. The watch features an independent hour hand, which is put into another time zone without adjusting the 24 hour and the bezel. Additionally, the “one-hour” jump attribute enables the hour to jump 1 hour at a time without affecting the moment or second hand. This feature is not present in the Submariner versions.
3. All existing Rolex GMT models game a ceramic bezel, unlike the Submariner versions.
4. The Rolex GMT versions currently available offer many jewelry embedded options such as diamond-paved dial, rotating bezel fitted with diamonds, sapphires and rubies and even diamond fitted lugs. Such jewelry choices are not available in the Submariner models.
