STS had no issue servicing movement and giving it a 2 year warranty.
I don't think they are known to be problematic .
I have a client with a really battered one and all we do is put batteries in it (he won't get it serviced) and it doesn't ever want to stop.
size wise mines 38mm including crown , but it doesn't feel too small even after wearing my other watches at 42mm
