Athys Moon 2134 Watch From Daniel Roth

Jul 07, 2009
The major watch specialists at Daniel Roth have developed a novel watch equipped with a new, equally beautiful and accurate, moon-phase mechanism. The Athys collection will not demand any adjustment for another 125 years, since it was dubbed Athys Moon 2134. It happens to be a symbolic creation, perfect to mark the International Year of Astronomy.

This year celebrates the 20th birthday of the brand as well as the 400th anniversary the world’s first telescope invented by Galileo. In commemoration of this event that proved to be a turning point in the history of mankind, the United Nations Organization has declared 2009 the International Year of Astronomy.

The Daniel Roth outstanding watchmakers decided to improve the existing moon-phase displays, often demonstrating their inaccuracy. In traditional mechanisms the disc, exposing two moons, includes 59 teeth. Activated by a one-notch rotation every 24 hours, it accomplishes a half-turn in 28 days and 12 hours.

Taking into account that the real lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds, the display thus demonstrates the error amounting to +44 minutes per lunar cycle, that is +8.81 hours per year.

The advanced astronomical moon-phase mechanism of the Athys Moon 2134 incorporates three wheel-and-pinion sets. The first accomplishes a full rotation in 24 hours, activating the second one in 7 days, which animates then the 135-tooth moon disc.

The last one completes a half-turn in 29 days, 12 hours and 45 minutes. It means that the relative inaccuracy constitutes just -0.02 hours or 12 minutes per year. Due to such high degree of accuracy the mechanism requires adjustment just once every 125 years!

The Athys Moon 2134 is powered by a supremely beautiful mechanical manual winding calibre (DR2300) created on a Frederic Piguet 151 base movement.

Manufactured in accordance with the best watch making traditions, embracing refined Haute Horlogerie finishing and the original design for pocket timepieces, this advanced 16-lignes Lepine type movement is powered by the brand’s conventional three-arm seconds hand. Aligned with the crown, it makes an integral part of the main gear train.

The sophisticated and graceful Athys Moon 2134 is also characterized by large Roman numerals, blued steel hands, a “railtrack” minute circle with Arabic numerals and a three-arm seconds hand at 9 o’clock. A date display at 4 o’clock and a raised depiction of the moon between 12 and 4 o’clock, performed in the same color as the case, are the other special features this model includes.

The push-pieces on this very watch serve as correctors. They are designed to make setting operations easier and avoid any risk of scratching.
