Max:
A complete service (polish or replace crystal, disassemble, clean,
assemble, oil) is gonna be at least $100. Less than that, they are just
rinsing it and re-lubricating (or worse, spraying with "one step"
cleaner/lube). Cheap service is worse than none at all, I've gotten a
number of watches treated with something similar that was popular in the
70's, I think -- leaves accumulations of hard green crud that won't come
off in normal watch cleaning solutions and has to be hand polished off to
restore operation. Horrible stuff
Good news is that while most manufacturers would recommend annual
servicing, with modern materials and synthetic oils that do not turn to
goo or evaporate, once a decade is probably adequate. 17 jewel Seiko
watches have some points that require more frequent service to prevent
wear, notably auto-wind pivots and gears. More frequent lubrication will
prevent parts replacement.
I've heard possibly true stories of Seiko's running more than 40 years
with no service whatsoever, though, and have bought a number over the
years that run fine with no evidence they have been opened or
disassembled (no screwdriver marks on the screws).
Dropping onto a concrete floor or something similar might reduce the
intervals between services at bit, though...
Of course, any time it won't stay wound long enough to leave it off for a
day or when timekeeping becomes too erratic or fast/slow it needs a
service.
