After ten years of research, Bulova’s Accutron brand this week unveils a new type of watch movement that relies on electrostatic energy to help power its hands, and places the movement into two new Accutron watches.
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 (powered by tuning fork technology).
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 movement. After a certain period of inactivity, this function will stop the seconds hand to alert the wearer that power is being conserved. An even more comprehensive power-save feature, called the ‘energy conserving function,’ stops all of the hands, which prevents power from being depleted.
Both new Accutron watches display the same shade of green on bridges and/or case rings to clearly reference historical Bulova Accutron watches, notably the Accutron Spaceview.
The Spaceview 2020 most directly recalls the open, avant-garde design of the original Spaceview, which offered a clear view of its tuning fork electronics.
The new watch offers a 43.5mm stainless steel case and clear case ring with dot-shaped primary hour markers, fit to a black leather strap. A limited edition Spaceview 2020, with a green case ring, will also be available packaged in a deluxe box set with an illustrated book “From the Space Age to the Digital Age.”
Bulova took a few more liberties when designing the Accutron DNA, which offers a more contemporary adaptation. The Accutron DNA case ring is a sportier with its squared primary markers and its sapphire crystal is domed. Case ring color choices of green, blue, black or gold-tone offer more variety.
In addition, the Accutron DNA is attached to the wrist with what appears to be a nicely integrated black rubber strap, and the watch’s case is also larger, measuring 45.1 mm in diameter.
Prices: Accutron Spaceview 2020: $3,450; Accutron Spaceview 2020 Limited Edition: $4,000; Accutron DNA: $3,300.
