In 1971, the Explorer II was officially launched, with a small window convex lens at 3 o'clock for easy reading of the calendar. An additional orange 24-hour hand and a fixed 24-hour bezel allow the wearer to easily distinguish between day and night. Naturally, this feature also makes it the watch of choice especially for cave explorers, volcanologists and polar explorers.

The Rolex Explorer II replica can also display time in two time zones. The traditional hand shows the time at the location, while the 24-hour hand indicates the time in the second time zone on the outer scale of the progressive scale. Thanks to an ingenious mechanical mechanism controlled by the winding crown, the wearer can easily adjust the time of the home when using the independent hands to "jump". The minute and second hands can be adjusted independently, while the travel time and departure time indicated by the 24-hour hand are not affected.

The Explorer II was redesigned in 2011 and the new case has been increased to 42 mm. The dial design is simple and elegant, contrasting with the Chromalight hour markers and hands. Luminous materials coated on hands and hour markers emit light twice as long as traditional luminous materials. Watches are clear and easy to read in any environment. The Explorer II is equipped with a 3187 self-winding movement developed and manufactured entirely by Rolex with a power reserve of approximately 48 hours.

As always, the 3132 self-winding movement equipped with the Explorer type and the 3187 self-winding movement equipped with the Explorer II are entirely developed and manufactured by Rolex. Only Rolex-authorized watchmakers can have a chance to see the true contents of the movement. Although the wearer can not easily see it, the movement is exquisitely polished and meticulous, and strives for excellence.

Both movements belong to the 31 series movement. The movement balance spring assembly is equipped with a large inertia fine-tuning balance wheel, and its fine-tuning nut accurately adjusts its inertial oscillation period. The balance spring assembly is firmly supported by an adjustable height balance plate, which improves the shock resistance. Equipped with a Paraflex cushioning device developed and patented by Rolex, it can increase seismic resistance by 50%. Rolex's patented blue Parachrom hairspring is made of a unique paramagnetic alloy made by Rolex. It is not affected by magnetic fields. It is still very stable even when the temperature changes, and its shock resistance is ten times higher than that of traditional springs. The hairspring is also equipped with a Rolex end ring to ensure that it can maintain regularity in any position.
