Rolex Datejust 16233 White Roman (16233 White Roman)

Rumor has it that the new Rolex Explorer II was ready for presentation in 2010, but that Rolex did not present this new face-lifted version of the sporty watch until 2011 - 40 years after the first Explorer II was launched.
For many years, Rolex has been respected as well as ridiculed for its conservative approach to case sizes: 40 millimeters seemed to be the biggest case diameter offered in the sports collection. In the last few years, we have seen more and more models with a tendency toward growth: Yacht-Master II and Sea-Dweller DeepSea both come in a case of 44 millimeter diameters, and now the Explorer II also offers a diameter of 42 millimeter.
The Explorer II has never been the most popular reference made by the famed Swiss watch brand. The Submariner and GMT models have been the favored siblings, but even these two models still offer a moderate case diameter of 40 millimeters. Maybe Rolex wanted to push needed attention towards the Explorer II, hence the extra two millimeters?
 

Large watch
42 millimeters may seem like a large watch. However, since many parts and details of the new reference have grown, the visual size does not seem that radical. The case, hands, crown and hour markers are in other words dimensionally on par with the new case diameter. Visually, that is.
Wearing the watch, however, does challenge the visual impression. The Explorer II is a large watch. Comparing this to Reference 1655 or Reference 16570, which came out even later, the size difference is almost shocking. As mentioned, this will please those who have not yet bought a Rolex because they thought the watches looked too puny on their wrists.
Inspired by the past
One of the obvious details on the new Explorer II is of course the orange 24-hour hand. "Freccione," as Italian Rolex collectors long ago named this hand, means "arrow". This is a feature taken directly from the Reference 1655 Explorer II launched in 1971. The 24-hour hand was not separately adjustable on the early version, though. It merely functioned as an AM/PM indicator. However, bezel design looks more like the bezel of the short-lived Reference 16550 that was introduced in 1985 and face-lifted already four years later.
 

Phantom hands
The hands of the new Explorer II sport a so-called phantom effect, which means the lower part of the hour and minute hand is painted black. This little detail makes the hands look like they float free of the arbor. This works well on the black dial version, and merely represents a great contrast on the white dial version.
Latest movement update
Reference 216570 is outfitted with Caliber 3187, which features the latest technical updates like Paraflex shock absorbers and the non-magnetic Parachrom hairspring, which "ensures unparallel reliability, and shock resistance," according to Rolex.
 

White dial winner
The white dial version, even if it does not correspond perfectly to the 1971 version that was only offered with a black dial, gets my vote as favorite of the two dial versions. The b, graphic black/white contrast makes it stand out as this watch brand really does not offer a lot of white-dial sports watches. Actually, only the Daytona and Yacht-Master II come with a white dial, but the GMT, Submariner and Yacht-Master models do not.
Oldies but goodies
This said, I admit to favor not only Reference 1655, but also the 16550 or even the 16570. Not only due to their case diameters of "only" 40 millimeters, but also because these earlier versions have a more tool-ish approach to horology. And this is, after all, where the Explorer II started - as an instrument watch for cave explorers.
Rolex Explorer II Reference 216570 is offered with black or white dial and has a suggested retail price of 6,400 euros.
