What can I do when my watch gains / loses too much time?
Watch accuracy depends on the type of movement used in the watch. Please refer to the information stated in the instructions for the appropriate accuracy standard. If you have any concerns about the accuracy of your watch, we recommend that you contact an Authorized Seiko Service Center or a
