21 Jewel Bunn question

[Dutto11]

G'Day All,
I have a 21j Illinois Bunn Special and have had it cleaned and oiled, but since getting it back it seems to be loosing time.
I have wound the regulator all the way over to the "S" position but it still runs slow.
I have had a look at the the two forks on the regulator that the Hair Spring sit in and it is is very loose and the spring is not being held firm by them.
Not being an expert I was wondering if the Hair Spring should be held firm by the regulator or is this the norm.
Many Thanks.

Sounds like you moved the regulator in the wrong direction, move to FAST to speed-up the movement.

The hairspring should be held close by the pins, but not enough to bind when adjusting the regulator.

if you had it serviced, it should have held time on return...

you should have returned to have it regulated....

Gary:

To add to what Terry has posted:

When a watch is properly cleaned, oiled and serviced, the regulator indicator ought to be within the center 50% of its total range when keeping accurate time. Actually, it should be in a narrower portion in the center, but 50% allows for some variation of the quality of service without considering the cost of that service. If the regulator has to be positioned outside of the center 50% of its range to obtain accurate time, then it is an indication that either the watch needs cleaning and oiling, or that something is wrong with the watch. If it comes back from being serviced with the regulator outside of the center 50% of its range, it means that the person doing the service has not found, or corrected, one or more problems.

Good luck,

Thanks for that I will take it back and see if the watch repairer can fix it , if not I'll take it another repairer.
It is to good a watch to just let it sit in the cupboard.
