Omega Constellation day/date caliber 1020

Just thought I would show my Omega Constellation which I bought new in 1978. As you can see it is gold/steel only I am not sure if its 18 or 14 ct gold though I do remember Omega recording it as 18 ct on the box when I got it back many years ago after service in Bienne. The watch has been fully serviced and repaired by Swiss Time Services and despite having to send it back under warranty due to a few unsatisfactory items Swiss Time really took excellent care the second time. What especially pleased me was the dial was cleaned almost to perfection. One feature of this watch is its outstanding timekeeping. I believe the caliber 1021 was a better movement as was also fitted to this model watch as it had three extra jewels but that is all I know. Perhaps someone can add to this.

The fast beat movements are highly accurate. Nice watch!
