Hi I have just recently purchased a Wakmann Triple Date Chronograph powered by Valjoux 723. But I found that the day and month does not automative change while the time past 12am or 31th. Any idea to fix it? Thank You Steve

...month is only advanced manually. That was common solution those days - what could be wrong with the day not advancing properly, no idea - should need a look under the dial. Best Suitbert
