Christopher Ward C9 Harrison Jumping Hour Swiss

The somewhat out-of-the-way British watchmaking brand has recently revealed its automatic Christopher Ward C9 Harrison Jumping Hour. Featuring a unique (well, maybe not that unique, but at least original and made exclusive for them) jumping hour complication module, it is going to be the most expensive model in their whole range.

If you came here searching for a “jumping hour” watch, you must be well aware of the fact that the complication itself is nothing new.

There are a great number of watches featuring this kind of design, both highly complicated and innovative, like the gorgeous A. Lange & Sohne Zeitwerk (Ref. 145.029 / 145.025), as well as more mundane timekeepers that come equipped with mass-produced movements with mass-produced add-on modules.

The new Christopher Ward C9 Harrison Jumping Hour stays somewhere in the middle.

Equipped with the well-known ETA 2824-2 automatic caliber, the gadget sports a unique Caliber JJ001 jumping hour complication module that was created by a German watchmaker Johannes Jahnke.

The 27-year-old prodigy has become famous when the German Lang & Heyne brand presented their King Albert of Saxony chronograph watch that retailed for around €100,000 and featured a column-wheel chronograph movement of his design. He was around 22 years old at that time.

While the Christopher Ward C9 Harrison Jumping Hour is not THAT expensive, the complication that it uses is no less ingenious.

You see, a common “jumping hour” module usually tends to be inert for about 40 minutes and then suddenly comes into action, voraciously accumulating the energy, which is needed for the hours disk to instantly jump from one position to the next when the minute hand reaches “00”. Although simple and easy to produce, such a design greatly affects the base caliber’s isochronism, which is absolutely unacceptable for CW.

The British brand doesn’t go into details, only saying that the complication module is engaged 60 minutes per hour thus preventing any drops and surges in the supply of energy.

As you can see on the pictures, the watch uses a pretty much standard regulator-style dial layout with a single minute hand and a trapezoidal Jumping Hour aperture at 12 o’clock.

A slightly recessed sector at 12 hours somehow reminds me of the beautiful Hermes Arceau Temps Suspendu, although, to my regret, the British timekeeper is clearly not as refined with its galvanized dial and a sort of crude eiloid guilloche pattern.

The whole setup is put inside a polished stainless steel case. Being 43 millimeters in diameter and 13 millimeters thick, the body of the watch is well-proportioned but is too large for my taste. If you will check the photo of the case-back (below,) you will immediately notice how large is the case compared to the relatively small ETA 2824-2 ebauche!

According to the British brand, the watch will retail at around €1200. Its total production run will be limited to just 200 pieces.
