I found this 19 jewels pin lever movement in a Seagull date watch. It is very strange why someone made a full jewelled 3/4 plate movement but with a pin lever escapemant? I guess it is a Swiss movement. Between it and the 9 jewels Zhongshan shock proof jewelled escapemant movement, which is a better one?, and which is more costly to make? I think I have seen similar Swiss movements sometimes with no jewels or with 1-2 jewels. Maybe Seagull added some jewels to those movements?
