I think this one is a Frankenstein, but I could be wrong I believe the early constellations were 17J bumper watches, the 1st rotors were I believe 19J then they went to 24. Looks like a rotor on this one when it should have been a bumper so I think the movements off. Also when I look at the dial something seems off the seconds width seems inconsistent at the date, maybe a refinish dial? Its 37mm, at $299 dont know if it is worth it as a franenstein.
