Replace bad coil - Watches

If you experience no sound (alarm) from your watch after battery replacement, that means the coil spring fell out of watch while the battery has been replaced. Coil spring is transmitting vibrations from watch movement to the sound membrane at the back cover of watch, and if it is lost, there is no physical body to transmit signal, thus no sound. Coil spring itself is quite tiny and can be easily lost without even noticing it, mostly because it is not soldered to the watch movement or sound membrane and as soon as the opened watch is turned over, the coil spring fells out. If you are not able to find the coil spring in/around the place where the battery change took place, there is no other solution but to visit your nearest watch repair shop and ask to fit new one. In case if you are lucky enough to find the coil spring, fit it back in to appropriate hole in watch movement inserting out-bent end into movement. In most watches coil spring holes are marked: C.SPRING/COIL SPRING/ C.S or similar. Hope it helps.
