The tuning fork prongs are around the two electromagnetic coils at the top of the watch that drive it. Bulova's "Accutron" watches, first sold in October 1960, [30] use a 360 Hz tuning fork instead of a balance wheel as the timekeeping element. [31] The inventor, Max Hetzel, was born in Basel, Switzerland, and joined the Bulova Watch Company in ...
The common frequencies used in watches were 300 Hz (ESA MOSABA cal. 9162, 9164 and 9210), 360 Hz (Bulova Accutron [9] cal. 214 and 218), Slava Transistor, Tianjin 'Yinchabiao', Prim Elton, 480 Hz (Bulova Accutron cal. 2300) and 720 Hz (Omega Megasonic cal. 1220 and 1230). Omega F300Hz and Speedsonics series are common examples of ESA MOSABA ...
Jewel bearing of a balance wheel, supported by a lyre-shaped spring. The Incabloc shock protection system is the trade name for a spring-loaded mounting system for the jewel bearings that support the balance wheel in a mechanical watch, to protect the wheel's delicate pivots from damage in the event of physical shock, such as if the watch is dropped.

Similar designs from many other watch companies followed. Another type of electric watch was developed by the Bulova company that used a tuning-fork resonator instead of a traditional balance wheel to increase timekeeping accuracy, moving from a typical 2.5–4 Hz with a traditional balance wheel to 360 Hz with the tuning-fork design.
Watch movements require regular cleaning and lubrication, and the normal result of neglecting to get a watch cleaned is a watch stopped at full wind. As the watch movement collects dirt and the oil dries up, friction increases, so that the mainspring doesn't have the force to turn the watch at the end of its normal running period, and it stops ...
