How accurate are moonphase watches?
Most of our moon-phase displays are 99.998 per cent accurate, so if the watch runs without interruption, a correction by one day is only needed when 122.6 years have elapsed. This is achieved with an ingenious mechanical transmission that steps down the rotation of the hour wheel.
What is a true moonphase watch?

How do you read a moonphase watch?
