I have an automatic which is gaining about five minutes a day.  I don't have access to an electronic tester and I would have to retard the movement at the balance wheel using the adjustment lever.  Say if the lever is at the half-way point (as it is on most unadjusted movements) how far would you move the lever "back" for a first go at retarding the mechanism?

Hey Stroppy,

Phew!  Tough question mate.  Very movement is different in the amounts you have to adjust, and without a timegrapher you'll just have to make small adjustments and retest until it's running within spec.

Also without the aid of a timegrapher you can dial-out beat error, so this is one piece of kit I would place high on your wishlist.  You don't have to spend a lot of money either mate.  At home I use a No.1000 and these can be purchase for around $200 smackers from from OTTO as of the date of me posting this ... worth every cent.

PS. Make sure you've demagnetized the movement before testing as this could affect it's accuracy.  Yeah I know, it's another thing to purchase ... but nobody said this was a cheap past-time :)

Or USD150 on aliexpress. I don't think one can work on mechanical watches without a timegrapher, beside setting beat and rate, it shows amplitude and pattern that are basically the primary health indicators.

Thanks Lawson and jdm.  The watch is only a cheapy and so the cost of buying anything like a timegrapher wouldn't be worried.  What I might do is just gently nudge the adjustment staff less than a mm into the negative and keep an eye on the watch over the course of a day.  If there's some improvement then I can work from that point.

I have heard that the better movement and watch makers actually set their watches via an industrial timegrapher before they send their stuff off to shops.  Pity the Chinese don't follow suit on their cheaper movements.

The thing is that without looking at the timegrapher you can't know if the watch is working correctly or not. The timegrapher or equivalent application is an indispensable tool. Beside, if the watch running fast it could be magnetized and demagnetizing should be done first. If you do not have these tools at this time, go to a shop that has tem.

move it.. wait a few hours,test it again a quartz watch - your phone /oven clock, if fast move it back a bit - reset to right time and wait a few hours.. repeat until happy enough?

the closer you get the amount of time you should wait will probably be doubled.. i.e. 24 hours..

see you back in a week or so lol!

If the watch has suddenly started gaining five minutes a day, the first thing I would do before adjusting anything is check if it has become magnetized. All you need for that is a compass. If the watch makes the needle swing, the watch is magnetized, and needs to be demagnetized.

Five minutes a day is well beyond just being out of adjustment.

If you have an iPad or iPhone you can download the Watch Tracker App for£3.99.

I find it quite useful at times for checking watches both mechanical and quartz, as well as clocks.  It doesn't give you the detailed information that you get from a timegrapher regarding mechanical condition of the escapement, but it certainly lets you regulate a timepiece, and shows fluctuations over time in graphical form.

Geo...thanks!  I will look for the Android version of that app in the PlayStore.  I also ordered a watch demagnetiser on Ebay for AU$16 so I will wait until that arrives from China, demagnetise the watch and THEN adjust it.  This forum has really improved my confidence in doing such things BUT it has also cost me money!  Since joining I've bought a new watch tool kit, a couple of boxes of many sizes of spring lugs and a couple of books.  I'm as happy as a pig in mud!:D

I have used a trigger type soldering gun as a demagger.  I placed the movement near the main case where the transformer is, switch on the gun and slowly move it away (say 5 secs) to about 1 metre,  This worked for me. I gather almost anything with mains transformer will work.  Also believe if you take the watch to the local store which has a security tag remover and scan it across slowly will also work.  I have a cheap demagger and it works well, I normally place parts in a plastic pot (ie plastic milk bottle top!!) to ensure they do not go walkies!   :unsure:

Just a note on demagnetizers: never switch them on or off with the watch near the demagnetizer. Turn the demagnetizer on with the watch about a metre away, bring the watch toward it and move it around in the magnetic field, move the watch about a metre away again, and then turn the demagnetizer off. Also make sure you're not wearing a watch on the hand that is operating the demagnetizer.

If you're old enough to a have an audio cassette tape demagnetizer, those make good watch demagnetizers too.

      Stem removal after fitting hands

      By oldhippy · Posted

      I used to just remove the stem pop the movement in its case then put the stem back in check everything then back on the timer.

      Stem removal after fitting hands

      That's the right technique Mal 👍 If you are ok with a loupe ( which I'm not ) then pick up the dial in your left hand and make a tripod holder out of 3 fingers and then exactly how Mal and me described with your right hand, press and flick out the stem at the same time. You need three fingers to do this, i use my ring ring finger , sounds like mal uses his little finger, just whatever you feel comfortable with. The key point and dangerous side to this is the tweezers or driver slipping off the release screw. Stablise your left arm by resting your elbow on your bench, so that you can hold the movement horizontally flat, use a x5 loupe to view  and good light so you can see well and have a good tight fitting screwdriver to push the release down. Or as suggested a pusher mounted solid upside-down somewhere then all you need to do is push your movement up to it. I'll rig something up in a bit to show you what i mean. Something like this, but tbh its better to just learn to do with your fingers.

      Thanks Michael, shes a real soldier, it would take a tank to knock her off her feet.  Shes surprised even me and i knew she was a tough cookie.  Good for you Michael, you keep at it. I've been reading your posts re. your watchroom they're inspiring and it doesn't matter how long it takes you to get there its about the journey. Rome wasn't built in a day, our watchcaves are our solitudes, our own little empires where we can shut ourselves away from the crap that goes on around us in the world. I look forward to seeing you progress, I have my own ideas how i like to do things. But in answer to your questions on that thread, just let your workspace evolve around you and how you work. You wont figure it out straight away but you will know when to change it and when to leave it alone. But most of all just enjoy it.

      That can be tricky. Sometimes I hold the movement from the edges in left hand and with right hand I push the release with tweezers and simultaneously pull the stem out with right hand pinky or something.

      I see what you mean. I must admit I’m not entirely comfortable with that but I can’t see a better method than what you suggest. I’d like to see something like this mirror with a short spike: https://www.cousinsuk.com/product/mirror-for-observing-movements Place it on, push the spike on the post with one hand and release the stem with the other hand. Minor problem, it doesn’t exist.
