Divers were presented with the first “Aquatimer” back in 1967, which was half a century ago, 50 years to be exact. And to celebrate the occasion IWC Schaffhausen is releasing a special limited edition with the extensive title of: “IWC Aquatimer Perpetual Calendar Digital Date-Month ’50 Years Aquatimer’”.

Over the years the “Aquatimer” collection in its various iterations has become one of IWC’s most popular models. But, even a winning piece can do with some innovation to breathe new life and attention towards it and reintroduce this model line to a new set of potential enthusiasts. So novelty is exactly what IWC has brought to this note worthy 50th anniversary.
The 49mm case is made from the new “Ceratanium” material with a matte black finish, which consists of a combination of ceramic with titanium, as the name confirms if you break it down (cera + tanium). Material innovation has been a strategic way of horology brands trying to distinguish themselves from one another, or simply as a marketing novelty which has had varied successes.
One example that comes to mind was “Officine Panerai” with the “carbo tech” or Hublot with their “Magic Gold” and also their “Berluti leather dial”; among other brands. Omega themselves have gone done this route before with a meticulously crafted ceramic and an unique one-of-a-kind meteorite dial, for their “Omega Grey Side of the Moon Meteorite”.
But, in any case lets focus more on this newly introduced “Ceratanium” where the combination of ceramic and titanium has produced a very light material with the: corrosion-resistance of titanium and the durability plus scratch-resistance of ceramic. Omega states it took their research and development team five years to finally get this new “Ceratanium” material up to their desired standards.
After assimilating and comprehending the origins and benefits of this new material we still have the functions to take in to account. The case has a transparent case back that allows to view the inner workings of the mechanical movement. And comes equipped with two push-pieces on the right-side of the case in order to operate the chronograph functions, plus a screw-in crown placed in between them.
While mounted to the case is a mechanical external/internal rotating bezel with a SafeDive system. It was a clever idea by IWC to have the bezel rotate just like a regular dive watch would, but have it geared up to cause the internal bezel to rotate as well, along with it. Topped off by a convex sapphire crystal with an antireflective coating on both sides, which also assists in keeping this watch water-resistance up to 100 meters (330 feet).
Time is exhibited on a black dial with white hour index markers, accompanied by smaller minute index markers also circling the dial. There are two sub-dials: a sub-seconds counter at the 6 o’clock position and a 12-hour counter at the 12 o’clock position. Plus the central hands and hour index markers have all undergone a luminescent coating, for an enhanced legibility.
Also has two double windows on the upper portion of the dial: the windows to the right-side indicate the current month, while the windows to the left-side indicate the current day; providing a perpetual calendar to this dive watch. These windows are also part of two “camouflaged” sub-dials, as we can see the awaiting numerals under the “gridded” sub-dials that permeate the middle portions of this predominantly black dial.
