I bought my first automatic watch, a Seiko 5. Soon I learned that if I didn't wear that watch in a day or two, it would lose minutes on the correct time before stopping. So I wanted a watch winder that would keep it on time when I wasn't using it, but I wasn't willing to pay more than the watch.

The Chiyoda Single watch winder to me was the best. It displays and protects my automatic in a lacquered case while winding it. I had to experiment with the settings, but the 3 and Bidirectional settings works very well to keep the time on the Seiko 5. I doubt I'll take it on travels, but sometimes there are power failures, so it is good backup. For those who have asked, the power adapter will take 100 volts (Japan) to 120 (US) up to 240 V 50/60 Hz outlet voltages. The pins on my adapter are US flat blade style, so I will need outlet adapters which can be purchased almost anywhere.

I've had the Chiyoda for over two weeks without any problems, and the seller is dedicated to honoring the warranty and improving this winder.
