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.
