I`m far better at fixing 'em than researching the history of obscure brands.
First one looks early-mid 60s, second one's probably early-mid 50s.
One thing to bear in mind when getting them serviced and sorted out: it takes just as much time and effort to fix a cheap watch as an expensive one, just reminded myself of that fact recently whilst working on a couple of cheap 60s Rotarys and an old pocket watch.
