This innovation indeed requires an whole alter within the style with the gear-train. It?s not an painless task. Yet, this Astrotourbillon movement has simultaneously tremendously improved the best way the timepiece looks, with another innovation. Its balance staff and escapement-wheel workers are placed on one facet of the carriage, in linear alignment with its rotational axis, instead of remaining positioned on exactly the same rotational axis since the carriage as normal.
The outcome turns out to be wonderful and exciting, mainly because we really can obviously see the tourbillon carriage between two dials.This hand-wound 23-jewel calibre 9451 MC Astrotourbillon motion composes 187 individual parts, operating at a speed of 21,600 vibrations for each hour using a 48-hour energy reserve.The Rotonde de Cartier Astrotourbillon watch holds its heart with an 18 carat white colored or pink gold situation measuring 47 mm in diameter, using a circular-grained crown in the very same materials and a sapphire cabochon.
