Adjusting time on lanco

[gary17]

Hey

This lanco is gaining about 3 min a

 Hour and I see no adjustment on balance wheel. 

How can I adjust it. 

Cheers

Gary

That's the regulator. But 3 mins/hour you are either magnetized or have a hs coil hung up or sticking somewhere.

The regulator arm is the one pointing towards the 6 o'clock lugs, the one pointing away from the stem is the adjustable stud carrier.

To slow the rate you rotate the regulator arm anti-clockwise, towards the stud carrier.

3 mins per hour is almost certainly beyond the range of the regulator though. I'm not sure but it looks like you may have some hairspring issues. Coils touching or stuck together; some good clear close up pics of the H/S will help to see what's going on.

Hi  Gary  The regulator The bit with the two pins in moves away or towards the balance pinning point, moving it away from the stud will speed it up and towards the stud slow it down but do it with care and do not damage the balance spring.  Can you let us have the calibre number.

The ony number I can see is under the balance and its. 

1004N.
