Combining its passion for aviation with a commitment to innovation, Hamilton decided to measure the accuracy of its mechanical movements during parabolic flights which took place from 5 to 16 October on board the Airbus A310 Zero-G.
Since 2011, Hamilton has incorporated in its mechanical watches a range of exclusive movements developed in partnership with ETA. These movements offer considerable power-reserves (60 hours for chronographs, 80 hours for 3-hand models). Seeking to maximize product research and development, the study was therefore be carried out on four different mechanical movements (H-10, H-21, H-20-S and the ETA 2671 calibre).
Conclusions will make it possible to focus the development and performance optimization of mechanical watches on two areas: earthbound users subject to low gravitational variations (1G ±1) and users participating in extreme sports.
