Mühle-Glashütte, the independent family company from the German town of Glashütte, has created a brand-new Teutonia model that captures the Moon for eternity in a special window above the 6 o’clock marking.
Underneath this specially formed window on the face of the watch, a lunar disc with a diameter of around ten millimetres rotates, completing a full cycle in 59 days. The disc contains not one, but two images of the Moon and is therefore able to provide a realistic day-by-day insight into its lunation from a new moon to a full moon and back to a new moon over a period of around 29.5 days.
It also displays an extremely lifelike depiction of what the Moon looks like. This impressive feature is the result of meticulous work by the watchmakers at Mühle-Glashütte, who have carefully reproduced the large and small craters of this astronomical body located about 384,000 kilometres away.
The disc also features the night sky surrounding the Moon in dark Mühle blue lit up by a multitude of tiny stars. The moon phase display is incorporated into a light-coloured face with applied indices and clearly marked minute graduation with small blue second and minute numerals. Another blue feature of this new watch is its lance-shaped hour and minute hands and thin second hand, all of which extend to the perfect length for clear readings on their respective time scales.
The case of the watch is a prime example of top Mühle quality. As is typical of the Teutonia family, the middle of the case features the company’s characteristic vertical finish, as always carefully applied by hand. The top surfaces of the volute-shaped lugs are polished and perfectly harmonise with the extremely straightforward new design of the bezel, which in turn stunningly complements the clean-cut appearance of the Teutonia IV Mondphase.
Inside the case, which is not only attractive but also water-resistant to 10 bars, a reliable automatic movement goes about its second-by-second work. The Mühle-version SW 280-1 not only features the lunar disc produced especially for Mühle-Glashütte but is also equipped with the company’s anniversary rotor and its patented particularly shockproof woodpecker neck regulation.
On top of all this, once its components have been carefully finished and assembled, the movement is put to the test in six different positions and regulated to achieve accuracy values of between 0 and a maximum of +8 seconds per day. This precision target complies with the German chronometer standard and has the main aim of ensuring that the Teutonia IV Mondphase reliably displays the time in hours, minutes and seconds without requiring any moonlight magic.
