The Diamond / Shanghai / Quan Shi 8120 joins the rotation (along with a Weishi 1000, which registered the 8120 at +16s/day). Still, it's a beautiful, well made piece

I've got that one too. Mine had the issue of really low amplitude (resulting in a poor power reserve). I actually had the watch serviced, which is silly, value-wise, but it did sort out the amplitude issue.

So, I noticed this afternoon that the time was way wrong...Yep, it stopped around 10 hours after I wound it about 20 times... I, uh, follow the @PoorMansRolex process for improving service life. I, uh, yeah, I invented it! Yeah! That's the ticket!
