Abstract
1432884 Alarm watches TIMEX CORP 27 June 1974 [5 July 1973] 28671/74 Heading G3T An alarm sounding device, e.g. for a watch, comprises a pin 14 of magnetic material attached to the timepiece crystal 10 and extending into the field of an electromagnet 20 so that the pin is directly excited when the electromagnet coil 20a is energized by an oscillator at the alarm time. As shown the coil is wound about a core 20b and attached to a mounting bracket 18 between permanent magnets 22. Pole pieces 24 are fixed to the magnets 22 and lie one on each side of the pin 14, which is ferromagnetic. The bracket is adjustable on watch plate 16 and the crystal 10 is excited at its resonant frequency.
