ELECTROMECHANICAL CLOCKS OR WATCHES (mechanical parts of clocks or watches in general G 04 B; electronic time-pieces with no moving parts, electronic circuitry for producing timing pulses G 04 G)
Note
This subclass covers electric features of mechanically-driven clocks or watches, such as electric winding of such clocks or the provision of electric contacts thereon.
