Functions (all functions exactly as gen):
- Chronograph: 30 minutes counter subdial at 12, 12 hr counter subdial at 6 and seconds counter in central hand.
- Day: left window at 12
- Month: right window at 12
- Date: center hand, numeral around dial
- 24hr: subdial at 9. This is 24 hr format of the local time, it's not a second zone
- Moon phase: window at 6
This movt is a A7750 modified to perform the additional function, other than chrono. It's the same movt we could find in the Omega Speedmaster Day-Date, which I own and it's being working flawlessly for almost a year. Also this mod movt has been stated as reliable in several posts. Of course to ensure a long life, if you buy it, sent it to service upon receiving it and/or do regular service.
