Just as climbing gear and other sports equipment has evolved in the past half a century, so has the technology and design of the Explorer watch.
The original model created by Rolex in 1953 for the ascent of Mt Everest that may appeal to purists and history buffs, is just a plain steel watch with a 36 mm black dial, a polished bezel, and an Oysterlock bracelet.(e.g.Rolex Replica Explorer II)
The functional models in the current Explorer II line have a 40 mm steel dial in black or white, an engraved 24-hour bezel, and a red hand which, used in conjunction with the bezel, helps the wearer differentiate day from night. It also features a 12-hour hand that can be adjusted to allow for changes in time zones.
