An idea came to me while looking at some of my watches and thinking, "I'd love to see this one made again, with a modern twist". So I made this video. Please enjoy, and comment below on which watches you'd like to see done again.
This one looks very cool.

At Baselworld this year, Citizen and Bulova debuted a new concept movement which has some of the features of the original Accutron, but which also uses a new-to-wristwatches technology to both generate power for the watch, and to move the hands.
The Accutron concept movement will remind Accutron enthusiasts immediately of the Accutron Spaceview, an original-production Accutron which had an open dial, allowing the tuning fork mechanism and transistor to be seen. The concept movement likewise exposes the mechanism, however, there's no tuning fork. Instead, two small turbine-like structures are visible in the lower half of the dial, which rotate rapidly when the watch is in motion, while the upper part of the dial is dominated by a near-identical, but larger, turbine – this rotates continuously, as it drives the seconds hand in a smooth forward motion that recalls the original Accutron watches.
The two lower turbines are actually electrostatic generators, while the upper, larger, driving turbine is an electrostatic motor. An electrostatic motor is different from a conventional electric motor in several key aspects. A standard electric motor consists of a central rotor, wound with wire through which an electrical current travels; this rotor sits inside the stator, which is a ring-shaped permanent magnet. As current passes through the rotor coils, a magnetic field is produced and the attraction and repulsion of this field with respect to the permanent magnet surrounding it, causes the rotor to rotate, turning the driving shaft of the motor.
