Rolex - The Evolution of the Explorer II
WORLDTEMPUS - 2 May 2011
The Rolex Explorer II (reference 1655) - originally only offered with black dial - was produced to meet the needs of cave explorers operating in the dark and not able to tell whether it was day or night. This explains the distinct orange fourth sweep hand on the watch, which indicates AM or PM via the 24-hour bezel. This design was nick-named "freccione" in the 1990s by Italian collectors, which means "big arrow."
Admittedly, the target group for this watch is rather narrow. One would think that Rolex would at least have taken other groupings of professional explorers that might benefit from this feature into consideration when the Explorer II was originally presented in 1971.
Radical change
Since 1971 the Explorer II has only been updated three times, including this year's relaunch. In 1985, Rolex introduced Reference 16550, which for the first time offered the choice of white or black dial as well as a new movement allowing quick date change and the possibility to set the 24-hour hand to a different time zone. The 16550 also introduced sapphire crystal and an upgraded font engraving on the bezel, and the hands were of a different and subtler design matching other Rolex sport models. Reference 1655's hand design was entirely unique to this reference.
Subtle update
These updated details were repeated when Rolex introduced Reference 16570 in 1989; to a layman's eyes the difference between Reference 16550 with a black dial and Reference 16570 will probably not be visible. The difference between Reference 16550 with a white dial and Reference 16570 is, however, rather obvious. The 16550 white dial version turned creamy due to a fragile coating. Also, the white dial version now had black hands instead of light-colored, white gold hands that actually made it hard to see the time with a light-colored dial in the background.
Faulty frenzy
Faults like the white dial of Reference 16550 turning creamy is, however, something Rolex collectors will pay big bucks for. Rolex today is a watch brand that oozes perfection and conservatism, which is why mishaps like a fragile dial coating is interesting for collectors around the world.
40 becomes 42
References 1655, 16550 and 16570 were all housed in a 40-millimeter case diameter, just like the Rolex GMT-Master, Daytona, Submariner and Sea-Dweller. However the new Explorer II sports a buffed-up 42-millimeter case, making it the biggest of the aforementioned ticking siblings, and 2 millimeters smaller than the Yacht-Master II and DeepSea.
Undoubtedly, many Rolex fans will appreciate the new, larger case, but I wonder if Rolex added the extra 2 millimeters to simply draw attention to the Explorer II, which has been overshadowed for decades by its best-selling siblings in the sports lines.
Of course, we will never know this as Rolex representatives are as tight about the company's watch production as the Oyster cases are about water.
