Tourbillon Moon

The Tourbillon Moon dial features a hand-crafted fragment of the extremely rare Dhofar 459 meteorite, an authentic piece of the Moon that fell to Earth. The Dhofar 459 is thousands of years old.

About 130 Moon meteorites have been found on Earth so far and some of these have helped our understanding of lunar geology because they originate from areas of the Moon that were untouched by the Apollo missions. The Dhofar 459 is such an example.

Its dark colour throws into stark relief the central golden hour and minute hands as well as the main spring and tourbillon escapement that are revealed by the dazzling open-work dial architecture.

The escapement at 6 o’clock is mounted in a rotating tourbillon cage that helps to maximise timekeeping precision by averaging the effects of positional variations caused by gravity, while the state of wind revealed by the visible main spring at 12 o’clock provides an organic indication of the available power.

The exceptional 18k rose gold case of this Meteoris Tourbillon comprises 50 components including the signature Louis Moinet crown guard and the display-back is just as spectacular as the dial-side, with the ‘octopus spring’ of the winding and setting mechanism taking centre stage.

The latter is effectively three springs in one – pull-out piece spring, lever spring and click spring, impressively radiating from the centre like the swirling legs of an octopus.
