Watch One: Rolex Explorer II (My Favorite Rolex)

Rolex Oyster Perpetual Explorer II Mens Watch 16570-WSO
Watch Two: Rolex GMT-II (The New Version)

Rolex Oyster Perpetual Date GMT-Master II 116710BKSO
If you look past the shiny or brushed exteriors, differing colors, different fonts, and overall differences in perceived demeanor, you will notice that these two watches are essentially the same. They both have a 24 hour bezel, they both have an independent 4th-hour hand, the dials are essentially the same, the date bubble is in the same place, and if you just look at the core of the watch you would be hard-pressed to find any difference.
So then, you might be asking, why make two different watch models in the first place?
You see while the fundamental core of both watches appear to be the same there is actually only ONE difference between the two watches that makes ALL the difference, and that is in the bezel. In the GMT-II the bezel (the ring around the watch that has the 2-22 numerals on it) can be turned either counterclockwise or clockwise, whereas on the Explorer II the bezel cannot.
Why have they done that?
Well the answer to that is separated by the very extremes of vertical airspace.
If the two watches share anything, it is the fact that they are both purpose-built watches, and while they are very similar, the purposes and intentions as to the use of these watches are very different. It doesn’t make too much of a difference these days since most Rolex models spend their days on some golf course rather than the extremities for which they were originally built, but back in the day Rolex sport watches were built with purposes for purpose-minded individuals. And just like the diving watch pioneer the Sea-Dweller, the GMT-II and the Explorer II were both built with a purpose in mind.
You see the original Rolex GMT was originally designed with pilots in mind. The idea was that the time would be set to Greenwich Mean Time (hence the name GMT) while the bi-directional bezel is turned either clockwise or counterclockwise depending on whether you are traveling westward or eastward through the time zones. The original GMT did not have an independent 4th hour hand. In other words if the time was 10:10 p.m. your 4th hour hand would be pointing toward 22 and that could not be changed. The GMT-II, however, allowed that hand to be independent, so that, in tandem with the bi-directional bezel meant that you could track a total of 3 time zones.
The Explorer II, however, was very different. Whereas the GMT-II is for pilots, the Explorer II is for adventurers. The reason why the 24 hour bezel doesn’t turn was because traversing time zones was not the priority in mind for the Rolex Explorer. The fourth hour hand, furthermore, was never really designed to track another time zone but rather to act as an a.m./p.m. indicator for those in the most polar extremes or darkest of caves where day and night cannot be distinguished simply by looking at the sky.
Whether or not you choose to get the watch for pilots or the watch for adventurers is your call, but either way you can’t go wrong. They are both solid watches with iconic status.
