I have one of these- it is only for 32768HZ analog quartz watches with a stepper coil type movement. They are pretty much useless for anything else (cannot "hear" a digital watch). And they are very badly made- I have had mine apart many times to clean the copper foil battery contacts, resolder components (not easy as the circuit is part encapsulated in black gooey resin) and replace the pickup choke component.
