IWC : 50th anniversary Aquatimer with a Ceratanium case

This year IWC are celebrating the 50th birthday of the Aquatimer, and they have just announced the latest of their celebratory models, a special commemorative limited edition in a Ceratanium® case called the Aquatimer Perpetual Calendar Digital Date-Month Edition “50 Years Aquatimer”.

Limited to 50 pieces, it has a digital perpetual calendar and flyback chronograph. The watch’s perpetual calendar displays the date and month in large numerals in the style of a digital watch, hence the name.

Ceratanium® is IWC’s proprietary alloy blend of ceramic and titanium. The titanium is to achieve a case that is light and strong, and ceramic for its protective properties. Another good point to note is that IWC are also highlighting how suitable it is for people with skins which are sensitive to other materials.

Let’s look at the dial.

In terms of the flyback chronograph function, there is an hour and minute totaliser at 12 o’clock. In terms of the perpetual calendar, the digital date and month displays are via windows at 9 and 3 o’clock respectively and clearly labeled. The leap year indicator is at 6 o’clock, embedded within the running seconds sub dial.

Inside the large 49mm sized case is IWC’s automatic Calibre 89802. This is the same movement that was used in the Ingenieur Perpetual Calendar Digital Date-Month released in 2013, although this one is not identical, some of its components (e.g. the rotor) having been blackened to match the watch’s overall aesthetic. The movement, with its perpetual calendar and flyback chronograph, has a power reserve of sixty-eight hours.

As a side note, the Ingenieur model was in a case made of titanium aluminide, so there is some degree over overall conceptual continuity with this piece.

Like all Aquatimer models, this watch features an external/ internal rotating bezel for setting the dive time. The watch is fitted with IWC’s proprietary SafeDive system, which ensures that the internal rotating bezel can only be adjusted when the external bezel is rotated in an anticlockwise direction. As a result, even if the external bezel is accidentally moved, zero hour – the time at which the diver can return to the surface without the need for decompression stops – cannot be exceeded.

Coming on a black rubber strap with the IWC bracelet quick change system, the watch has a water resistance of 100m.

Aquatimers are historically sporty watches, but if you aren’t so much into the ‘all black’ look of this one, there is also a less-sporty-more-dressy 18 carat red gold model which features a blue dial. It is also limited to fifty pieces.

The special-edition Aquatimer with a Ceratanium® case will be available is a boutique-only model available from this month, and has an RRP of 50,000 CHF.
