Citizen Response We are happy to hear that you like the look of your new watch, but sorry about the issue you're experiencing. As with any automatic watch, it requires regular movement or winding to keep running. To ensure optimal performance, your watch should be fully wound. The Tsuyosa has a 42-hour power reserve, so when fully wound, it should keep running for that duration. We appreciate your feedback and we’ll reach out to you via email to learn more about your experience and offer further assistance.
