With the end of patents for majority of mechanical ETA movements the market has started to see a greater number of alternative clone movements based in designs now over 40 years old.
One of such movements is the Hangzhou 6300 Automatic Movement which is based in the ETA 2824-2 movement and with majority of its parts interchangeable with the ETA 2824-2, Sellita SW200 and Seagull ST2130 movements.
There are some rumors that Hangzhou used to be one of the suppliers of unfinished movement parts for Sellita (that also used to produce movements for ETA itself) in the past but that is merely a rumor based in no real evidence. Regardless of that Hangzhou is one of the major mechanical watch movement producers in the world having in its portfolio a multitude of movements that are an alternative to the scarcer Swiss counterparts.
