Hi.
In the old days it was IWC policy not to have watches running slow after
servicing. I had my 3536 serviced recently because it was running slow (~
-5s per day) and hadn't been serviced in the ten+ years I'd owned it. I had
to take it back immediately after the service (< a week) because it wouldn't
wind manually (the crown just jammed and wouldn't turn) and told them it was
running slow (~-5 secs per day) and I wanted regulating to run a little fast,
not a little slow. It's still running slow (about 5 secs a day). I've got a
couple more that need a service and if the policy for regulating them a bit
fast has changed then I'll get them done somewhere else.
Thanks in advance for any help.
