Hi Sir...Thanks. The Hairspring is pretty clean. Thre regulator is now pushed till the slowest setting (-) . But still the watch run fast. Any guidance? :) Alex

Hi bonex_boat99,

If you have one of the more common style pocket watches like Elgin, Waltham, Illinois, etc., the adjustment of the spring tension on the balance wheel spring or "hairspring" is virtually the same for most models. It doesn't matter if the watch is a Crown (stem) set or lever-set. Open the back cover, and most watches will have a second dust cover protecting the movement.

On the main housing cover of the balance wheel and hairspring configuration is a small adjustment lever. Note the current position of the lever now, and move it slightly (very, very slightly) in the direction you need to correct for. Most movements will have "S" for Slow, and a "F" for Fast. Of course this is pretty obvious for most people. This adjustment will cause the balance wheel hairspring to become a little shorter or tighter for the faster adjustment, and therefore, cause the watch to speed up slightly. The reverse procedure will "lengthen" the spring, and slow the movement down.

Since you're apparently doing this yourself or for an associate, be careful with these adjustment, making certain to not slip and damage the wheel or spring. Run the watch for several hours, and compare the timing accuracy with your known amount of error, then make further adjusts if needed.

Of course, you still may wish to take it to a certified watchmaker or repairman for this service, especially if the watch is a heirloom or otherwise valuable piece.

Good luck with this procedure! Let me know if I can be of further service.

Thanks, Bill

You have to clean hairspring. Unless the hairspring is spotless, there is no way the watch will keep time. Make sure hairspring coils are even and not touching. Rate me, please.

I am experienced at replacing hairsprings, but believe me if you are not trained your just asking for trouble. Your may get them out, but getting a new on in is a different story and if your don't know how to do this you won't get it to keep running. You may give it a little push and it just won't keep running. I recommend you let a qualified person do this for you to avoid a lot of frustration on your part

well you should check the settings more carefully

dont do anything!the watch needs service.perhaps somehow the watch fallen in a hard surface and something moved or broke in the balance wheel.the hairspring the pallet or the wheel have serious damage.to have your watch healthy wateresistance and accurate try to find a seiko authorized service center to repair your watch!

The hairspring in your watch must be degreased and demagnetized.
Coils of hairspeing is touching and this is why your watch is running so fast.
This can be done at any watch repair shop and should not cost too much as no repairs will be carried out. This job can be done in an hour, so, while you'll be shoping or having a cup of coffee.
Find your nearest watch repair shop and ask to sort out the hairspring.

Rate me, please.

Such a fast gaining usually is caused by dirty or magnetized hairspring, resulting in uneven coil amplitude (some of the coil rows are sticking together or touching each other). This causes the watch to run unbelievably fast.
To get the watch properly fixed you need to give to the watchmaker.
Alternetively; you can fix it yourself, but it will not last long.
For this you will need:
Case opener,
Dust blower (resin ball with nozzle),
Lighter fluid (ZIPPO),
Dropper (like one in eyedrops package).
Do as follows:
Open watch caseback,
Check for the fastest moving part in watch movement and you will see the hairspring fitted on it (pulsing outwards and inwards very fast).
Fill the VERY CLEAN dropper with lighter fluid.
Put ONE drop of lighter fluid on hairspring (DO NOT TOUCH IT),
Wait for a 10 seconds,
Dry out the lighter fluid with dust blower by vigorously squeezing it and pointing the nozzle on to hairspring from approx. 2-3 inches away.
Lay the watch on the table (dial down) and cover it with a clean, dustless cup. Leave for 15 minutes.
Fit the caseback on and enjoy your watch again.
Do not forget to rate, please.

If this is brand new watch, the best way is to bring it back to the dealer to get it fixed under warranty or you will have to pay if the warranty expires. And watch repairs are quite costly.
By the way- there is no reason to panic yet, as this sort of mechanical failure happens from time to time even to brand new watches.
The reason of this can be:
1) Watch has been magnetized,
2) Watch hairspring has some dirt particles sticking onto it,
3) Hairspring can be greasy,
4) Jewel holes are not oiled properly,
5) Uneven coiling of hairspring,
6) Index hasn't been regulated properly.
I understand that all this sounds a bit too scary, but in fact it is no big deal and any decent watchmaker can fix all this quite quickly, so, do not think your watch needs a complete rebuild or similar action.
About removing that screw: There must not be any screws in the winder, but as I do understand, your watch has a screwdown crown (winder) and you have to unscrew it prior setting hands or date. Screwdown crowns are very nice feature as your watch gets very good water resistance, just don't forget to screw it back on.
Don't forget to rate, please.

Usually when a watch with a mechanical movement is running fast its is because the adjustment on the hairspring is advanced to far. Since it wasn't running fast to begin with I can assume its because something was knocked loose. It is possible that a tiny drop of oil was on the hairspring and by knocking the watch two coils are stuck together by the oil. (this usually only happens if it has been over oiled by an amature watch repairer) Magnitization is possible but pretty unlikely, unless you play with Big coils of wire that are carrying a LOT of current. Either way, unless you know what you're doing and have the right tools, you are looking at taking it to a Tag repair center. Since a simple tune up can cost about $250, I'd expect to pay $400 to $500 for that one. Welcome to the wonderful world of high end watches.

the hairspring may have jumped up over the regulating pins effectivly shortening the hairspring this requies a watchmaker to repair.
