The perfect technology and the arts, and Chen, Tourbillon century rebirth of the classic

Tourbillon innovation process is known to enhance performance to watch tourbillon accuracy of greubel forsey, 2008 Nian watch exhibition venue in the formal launch of four body Tourbillon 30 degrees in order to create their own complex technology challenges of the high precision of the ultimate goal of mechanical watches , spent five years before they developed out of the ball-type differential gear strikes a balance between the force of gravity caused by mechanical error of all places, to achieve a balanced power output, stability, and to enhance timekeeping accuracy, even beyond the Swiss Observatory certification standards, rated as the highest of contemporary precision tourbillon.

correspond to celestial bodies to run, the ball-type differential gear to resume Tourbillon synonymous with the glory of past accurate

1850 ~ 1880 era, Tourbillon was “precision” and synonymous with, but since the advent of wrist watch, watch the original design of the tourbillon device has been reduced to craft ornaments, practical operational accuracy has lost its meaning, the focus lies in the plane tourbillon device, can not adjust to watch from various angles to wear habits; in the Swiss watchmaking industry respected greubel forsey popular 30-degree double tourbillon body was found the mysteries of precision Tourbillon reply, after five years of R & D , in 2008 launched a 30-degree four-body tourbillon is equipped with well-developed the ball-type differential gear, adjust the force of gravity caused by the different directions of the small error of watches, but a further evolution to reach the accuracy requirements, would be far better than Switzerland, which has been beyond the astronomical certified catamaran Tourbillon 30 degrees every day of error of four seconds.

two basic invention, was born after the evolution of precision tourbillon

. gp This greubel forsey quadruple tourbillon à différentiel sphérique watches combination of art and the pinnacle of technological innovation to make. Yes robert greubel and stephen forsey second fundamental inventions, this invention allows them to watch an artist, author of a new high of

degree of technical data technical data

Solid 18k gold and black gold

Strap

black alligator belt and gold buckle, hand-carved greubel forsey tags

Four-body Tourbillon 30 degrees to achieve precise requirements of the mystery lies in the basic invention of the first “30-degree twin-Tourbillon” After gf studio tests and found that tilted 30 degrees is the most consistent with a variety of bearings wearing habits and does not undermine the power transmission to the point of Tourbillon, gf, and this patent shows that entities in six directions at the same time through the test results, the daily error of only 4 seconds, accuracy is better than the Swiss Observatory certification standards (+6 ~ -4 seconds), gf 30-degree four-body Tourbillon is the foundation through the second differential gear inventions ~ ball (spherical differentiel), two 30-degree twin-Tourbillon, respectively, after correction of minor errors in power further adjustments to achieve the perfect balance of gravity on the balance wheel impact, leaving watches achieve higher accuracy.
