Yes stroppy, they had reputation as cheap and nasty, but some of them just kept on going, funny thing I recently bought a batch of 8 watches because it contained 3 with quality Swiss movements of the other 5 two had Baumgartner 866's, two had MAM 3467 movements, all four of them are up and running - the three "quality" movements are all in the parts bin as all had broken parts, too expensive to justify fixing in relation to end value.
I am constantly surprised by cheap movements, even quartz, always seem to get stuck with a heap of quartz when you buy bulk lots, mostly cheap Chinese/Hong Kong make with Seiko PC21 ot the equivalent cheap Citizen movements, pull out the old battery clean out the crud and install a new battery and they fire up, the good quality movements when the battery leak it seem to invade all the electronics and destroy the circuit.
Before I will buy any quality brand quartz watch that "just needs a new battery" I check to see if a replacement movement or equivalent is available, been burnt a couple of times, unfortunately even good brand quartz watches don't seem to hold their value well enough to justify spending $100 + on a replacement movement to restore them.
