There you have it! you are on the right trackbmsm wrote: ↑October 14th, 2020, 6:22 am According to the Seiko manual, the charger output is 9v/0.5A and the alternating current magnetic field transmission(approximately 1 kHz). I'm not fare from that, I'm using 5v/0.6A.
They also expect the watch to get warm and even write this alert:

- Be careful with the temperature of the watch, when handing the watch to the customer.
