My $300 two year old watch stopped, and I went to get the battery changed where I bought it. [View all]

I was informed at the store that it would need to be sent out if I wanted it fixed for a battery replacement but the problem was easily addressed by leaving it in the sunlight for 10 days.

I had no idea of this, but it appears that it's solar powered; the watch face is a solar cell.

I wear long sleeved shirts at my job.

This explains why it would seem to restart and then fail.

This sort of thing is in store for the entire planet, by the way, but don't worry, be happy.
