  1. Yes if you're not careful measuring something is fine as this will be an issue. Micrometers are better than veneer calipers but there like a little tiny vice and you're going to put a lot of pressure on your pivots just because it's going to be really easy to do. They do make holders for the micrometer or bench micrometers where micrometer sits on the bench it makes it a little easier to use but that's a lot of pressure conceivably you going to put on a tiny pivots. But there is a micrometer that does work well I'm attaching a picture unfortunately it's pricey. Then there's the jewel gaug

  2. Outstanding in that you did this. I thought I was going to have to give my classic lecture on why you can't do this but you solved that problem as you did it and it doesn't work congratulations. Then yes I'm really happy you did it because having given the lecture of you can't do this it's nice to have a proof that you really can't. If it's an American pocket watch hairsprings wrh vibrated separate from the balance wheels. This is because the terminal curve's have to be in a very exacting position. Balance wheels were matched to the hairspring they had the timing screws to do it. Although I ha

  3. There is no threaded holes on this side either? Then it's tapered shape and friction fitted. If you feel lucky - Kendrick & Davis Inverto Staking Tool is your friend. But would check the opposite side first to see if it will be safe to apply pressure to reinstall it. Some of these studs have thin walls filled with some sort of epoxy to hold the hairspring.

  4. Hi all, I have an old Bulova that has been on and off my workbench for a few months now - it was one of the first watches I attempted to service. The original staff was bad, so I ordered another movement of the same caliber (8AH, or ETA 1000) in the hope of transferring the balance complete. After receiving the parts movement, I then completely fouled up the hairspring on the "new" balance, due to a tragic combination of large overlapping centre wheel and the softness of old Bulova hairsprings (I now never dangle balance wheels from the cock - a harsh lesson learned). I've just got a

  6. I plead insanity your honour. As a result of my insanity and my inability to locate the off button on ebay, there is another (lopsided) Metamech on its way to me. In fairness the first one has just had the final touches put to its shellac and looks almost new. I'm not sure if my woodworking skills are up to matching the missing piece of this latest one however, so I may need to do a little creative thinking on that score. This one is even older than the first and has the magic start button on it and the patented "tick" which you can switch on or off. As to the date

  9. I can't think of a better advice than to watch Mark lovic video showing how he manipulates a hairspring. Just google and watch it on youtube.

  10. You are right( I said it wrong in my post) , yes you lighten the wheel, however, keeping the wheel poised is easier said than done and if you attempt it with hairspring on the wheel, its then dynamic poiseing so we keep increasing the stakes and if you remove the hairspring then one normally risks increasing beat error " that is if we now have the least to zero beat error". I don't think I can add anything to what Mike and John have already said, I personally have a safety razor to take the spring off the wheel with and a nail clipper to cut , so I choose the cheapest route to getting t

  12. It's the opposite side (under the dial) that you need to open and check. I never put the dial on before verifying that I am able to wind the watch, move "hands", adjust calendar, etc. Also check clearance between Hands. https://eterna-fanatic.com/calibre-965-1020/

  13. I see now its a fixed stud holder( Dr ranfft), so if your poising skil is decent, increasing the weight( inertia) of the wheel is actually the prefered approach as opposed to shortening hairspring length, for the simple reason that you will loose some amplitude with shortening hairspring length.

  14. For resurfacing my carbide burnishers I use a 45 micron / 280 grit diamond plate for my finest one, my regular burnisher is done with an 80 micron resin bond diamond wheel. I think 600 grit is too fine. To take off about 0.01mm at that diameter should take anywhere from 10 seconds to a minute depending on the burnisher and pressure. Thin oil is good, many here use almond oil, some use lavender oil. The Mitutoyo 0.001 reading mics I've seen have been digital and are even more unwieldy and have less feel than their simple brothers, I bet a coke you've squished your pivots

  15. It all depends on how hairspring is attached to the stud and tools at your disposal. If glued, you might just take a solder gun to the stud and burn the glue. If pinned ! unpin. if laser welded remove the stud in a staking set. You might just remove cock and balance assembly, place it on a hard surface ( cock down, balance up) then press on the stud arm to break the stud loose then push the stud stud out with pair of tweezers, one prong of tweezers under the stud arm, the other on the stud.

  16. This is what happens when you get really cheap watches they skip parts. You may find that it's not actually tapered it just Friction in as it's probably really not meant to come apart. But you may still be a little push it out it's probably not tapered either. The other option would be to unpin the hairspring providing they have a pin? What would be nice is to have a parts list with pictures but I bet that doesn't exist.

  19. The reason why the screws are on the bottom side is for visual effect and because it's not considered something you would remove normally at least normally to regulate the watch unless there's a problem. Sometimes instead of having a screwdriver slot on the end they will have holes so you have to stick something tiny in the hole and rotate it. I have a link which has information on 12 size Illinois watches you might find this interesting http://illinoiswatchguide.com/grade219.html

  20. I see such scenario very often and it does make sense as the regulator and also jewel holder are made of steel while the Balance Cock is copper based. Thus, the threads will last longer.

  23. This was going to be another "Timex Tuesday" watch, and then I thought I might make it in time for a "Timex Thursday" instead but it took a little more work than I expected, so I guess its a Timex Friday today - 1971 Timex Viscount (model 46660 3271). I lost count of the number of times I had this apart, but now its fully functional and clean as a whistle.

  24. Yes that is what I am saying. Assuming the spring you received are of larger width scratching the barrel from inside. In which case lubrication or serial number of grease wouldn,t help much. If my lidless idea do not appeal, test with one of the old springs. Regards joe
