The Rolex Explorer II Vs the Rolex GMT-Master II

The Rolex Explorer II was launched in 1971 primarily for the speleologists (cave explorers). This model features a fixed bezel engraved with 24-hour track and a special 24 hour hand (initially orange in color, now red) which together help to distinguish AM from PM. This feature has proved to be a boon fo cave explorers. They spend days together exploring deep caverns where daylight is nil. As a result, keeping track of the time becomes difficult. Rolex GMT-Master II, an improved version over the initial GMT-Master (introduced in 1954), was launched in 1983. This 二手錶買賣 model is meant for the pilots who need to travel through multiple time zones. It features a special 24 hour hand and a bi-directional rotating bezel, designed to display the time of any two time zones simultaneously.

How does the Explorer II Resemble the GMT-Master II?

The 24-hour engraved bezel and the extra 24-hour hand in the Explorer II make it resemble the GMT-Master II. These features between the two enable them to display the time in two different time zones. In both the models, the 24-hour hand points to the 24-hour time represented on the bezel. For instance, if it is 7:00 AM, the 24-hour hand will point to 7 on the bezel. If it is 7:00 PM, it will point to 19 on the bezel. Another feature common to the two models is the “jump hour” feature. This feature allows the 12 hour hand to be set to a different time zone without adjusting the 24-hour hand and bezel. This is done by first unscrewing the winding crown and then slowly turning it clockwise or counterclockwise. This adjustment will result in jumping of the hour hand one hour at a time without stopping the minute and seconds hands. In addition, the independently adjustable 12-hour hand allows the wearer to simultaneously check the time in any two time zones.

The initial Rolex Explorer II model had the same caliber movement as that of the GMT-Master 1575.

Some other common in the two include the following:

* Mercedes hands in place of old, large stick hands

* A slimmer, scratch resistant synthetic sapphire crystal

* Crown guards

* Cyclops lens over the date aperture

* Self-winding and waterproof to 100 meters/330 feet

What is the Difference Between the Two?

The major difference between the Explorer II and the GMT-Master II is that while the Explorer II features a fixed bezel, the GMT-Master II has a bi-directional rotating bezel.
