If it is not worn for a day or two the “automatic “ feature stops and you have to reset time/day/time. I would not buy another watch without a battery or eco-drive.
Citizen ResponseWe appreciate your feedback. Choosing an automatic watch is an individual preference. As you may know, an automatic watch is self-winding and powered by the motion of the wearer’s wrist. If the watch is not worn often, it would need winding because of the intricate movement. What’s very desirable about automatic watches is their craftsmanship and lasting quality, and like Eco-Drive watches, they never need a battery. We hope you’ll enjoy your automatic watch for years to come.
