Seagull's ST6D 23 jewels automatic movement was widely used for those fake watches. It has an accuracy of +,-45 seconds/day, but can be regulated to a much higher accuracy.
However, there are far more fake watches with a modeified ST6D than an original Seagull lady automatic watch. Even long time dealers seldom saw an lady Seagull automatic watch.
Liaoning Watch factory also made a much less common lady Beijing Railway 40th anniversary watch, and it has a rare 24 jewels ST6D movement?!
Also a fake lady Rolex is much less often seen with a slightly different ST6D movement.
Here is an image of a fake lady Rolex and a Beijing Railway lady watch. There are some details difference for the two ST6Ds. The fake Rolex probably is a later version, as it has a well made S/S case and a better made thick S/S band. I take the fake watch only for reference.
