The cheaper Pro Divers (the 89xx series) uses the Miyota, the more expensive ones (the 99xx series) used ETA 2824 or 2836s until a few years ago, and now use the Sellita SW200 or SW300 (clones of the 2824/2836).

Both the Sellita and Miyota movements come out of Chinese factories. The Sellitas are assembled in Switzerland, to Swiss specs with Swiss quality control. I've torn down several of those movements and they are quite good.

However, again--if you expect the lowest-grade ETA or Sellita movement to perform to the same level as a COSC certified 3135, you're going to be sorely disappointed. The ETA 28xx ebauche is a fantastic, well-designed movement, but it takes a lot of careful tweaking to make one run to within COSC specs. A lot of the lowest-grade ones never will.
