All our watches are fitted with a standard silver oxide button cell battery; available at most watch stores and/or jewellers.

Batteries fitted in our timepieces are expected to last between 2 to 3 years depending on external factors such as external temperature, humidity, air pressure, etc.

Please set the time to 12:00 sharp and check that the crown is pushed in, completely, against the watch case. Wait 20 minutes to see if the minute hand has moved. If this does not resolve the issue, kindly contact us and we will be happy to assist you.
