The watch serial number matches the model, so at least those things are correct (if the serial number on the card matches the watch). This has the F. Piguet based Omega Cal. 3303 inside. If it was serviced, best to make sure it was done by someone with access to Omega parts (and someone familiar with this movement), as several improvements were made to this movement over the years and upgrades need to be done on most of them that cross my bench.

Not everyone will take these on for servicing, so if it hasn't been serviced or hasn't been serviced properly, might be an expensive service...

Once these are upgraded they are quite reliable movements in my experience.
