The new watches , the Accutron Spaceview 2020 and the Accutron DNA , are the premiere models within the newly separated Accutron brand , and each feature designs that echo the dress of the historical Bulova Accutron Spaceview of the 1960s , the world ’ s first electronic watch , at the time powered by electronic tuning fork technology .
THE MOVEMENT The new Miyota-built movement , which Bulova previewed in 2019 , relies on both a power cell and on spinning turbines that react to the action of the wearer ’ s wrist to re-charge the cell .
The larger of the three electrostatic dial-side rotors , which is actually a motor , spins furiously while the watch is worn to directly power the seconds hand . The smaller two electrostatic generators , propelled by a more conventional rotor inside the movement , electrostatically charge the power cell , the integrated circuit and the quartz-based timing components that control the hour and minutes hands .
The watch ’ s energy is stored in an accumulator cell that powers two motors . Integrated circuits synchronize the motors to provide accuracy to +/ - 5 seconds a month . Depending on how often the watch is worn , Accutron says it expects the electrostatic power feature will allow the watch to replenish its power for up to a decade without requiring a cell replacement .
In addition , Accutron has built a power-saving function into the new
