Glashutte Original Senator Perpetual Calendar German

The refreshed Glashutte Original Senator Perpetual Calendar Automatic (refs. 100-02-22-12-05, 100-02-25-05-04 & 100-02-25-05-05) offers one of the most legible mechanical calendar timekeepers money can buy. You will need a lot of money to get one, though: it is about twice as expensive than your normal ETA 7750-based “perpetual calendar” watch in a standard rose gold body of similar size.

Compared to the outgoing version of the watch, the new perpetual calendar offers a reworked dial that, while sporting the same general layout, looks even more elegant and completely fresh.

The first of all, the original sword-shaped luminous hands were substituted for their signature “vintage” combination of a curved minute and a spade-shaped hour hand.

Although the new hands lack the luminous substance, it is absolutely okay in this particular case, since this is clearly a classic dress watch, not a sporty timekeeper as previous iteration of the model.

Accordingly, the applied hour markers were also replaced with white, bold Roman numerals and a printed minute track, also in white.

The main part of the dial, the perpetual calendar interface, seems to be completely the same with the day of week aperture placed at 10 o’clock, current month at 2 o’clock, their trademark Panorama Date display at 4 o’clock and a the unavoidable moonphase indicator staying between 7 and 8 hours.

The red dot that you can see in the upper half of the dial closer to its center is a leap year indicator and it tells you that it is now a leap year. There are also yellow, black and white dots on the small rotating disk to indicate the successive years.

The reason for such a unification is simple: the refreshed Glashütte Original Senator Perpetual Calendar is still powered by the same GO Caliber 100-02 manufacture-made self-winding movement. Which is just as well, since the movement is nothing but gorgeous.

Built on 59 jewels, the automatic movement beats at a frequency of 28,800 vph and features exquisite, yet discreet decoration on its three-quarter plate and the skeletonized winding rotor with famous Glashutte stripes and 21-carat red gold oscillating weight.

Done with extreme attention to details, the decoration may be especially appreciated by those, who grew somewhat tired of the omnipresent Cotes de Geneva and the inevitable Barleycorn guilloche motif that the Swiss watchmakers are so proud of.

As you may gather from the photos, the movement is operated with a number of push-buttons strategically placed at around 2 hours (month adjustment,) 10 hours (day of the week adjustment,) 9 hours (moon-phase adjustment,) 8 hours (sum correction for date, day of the week, month, and yearly rhythm,) and 7 hours (second hand reset function) on the sides of the case.

I truly hope that they do sell the watch with a stylus made of some soft plastic or wood, or something. It would be a great shame to scratch the mirror polished case in the first day of using the brilliant timekeeper.

According to the German manufacture, the refreshed watch will be available in two versions. One (Ref. 100-02-25-05-05) will come on a black Louisiana Alligator leather strap and the other (Ref. 100-02-25-05-04) will be offered on a sportier (but clearly inappropriate) black rubber band.

Prices are still unknown*, but they will surely be around €30,000 or even more getting into account almost constant increase in gold prices.

    Really, who cares for yet another classic watch that’s just like a thousand others? If you don’t have the imagination to design a watch that stands out, why tell the world you have herd mentality?

  2. Give me that dial and movement with a stainless steel case please. I’m tired of paying through the nose for white gold or platinum when steel looks the same but costs so much less.
