  1. I wonder why dont you use the quartz movement tester? In similar case, I often test the movement itself before placing another good/sealed battery
  2. I'm going to clean all parts by ultrasonic. I haven't used oil on the pivots of pallet (both upper and lower). For the fine tooth combe, can you suggest alternative way because I dont have the comb
  3. Exactly. By somehow 2nd round of the hairspring is stuck in the curb pin of the regulator. So it made very strange rate as shown in the video. That's right way I've gone through. Finally I have removed the stuck hairspring from the curb pin. Now the problem is the balance wheel stops after a few beats. I've tried to clean the pallet, lever pivot, demagnetized the balance wheel. Nothing works. The balance wheel still stops after 1-2 beats. Still need some more advice the the case.
  4. Hi I’m trying to service a Seiko 7s26 and encountered a problem of strange rate as shown in the video http:// The rate should be 21600 but it varies from 12000 to 25200 and sometimes could not be detected. I’v check both pivots of balance wheel. They are in correct position. Please look into the video and give me advice Thanks Khoa
  5. The pallet fork moves with each rotation of the escape wheel. With photo can not judge if it is evenly lying or not. However you can check yourself by gently notch the fork from both directions. If it moves with escape wheel it seems to be okay. Remind that you should check the pivot of the pallet fork before tightening the screws. Sent from my iPad using Tapatalk
  6. AndyD from your photos, the movement is 0S20 not 0S60. the stem part number for both is 065-453.
  7. I don't have tools to remove the balance and install it on the old bridge. It could be the end- shake problems because if I pressed down the end of bridge it would run faster. I was looking for complete balance and bridge for ETA 2804 but was unable to find it. Could you please suggest any other way to fix it? Sent from my iPad using Tapatalk
  8. Yes you are right. The roller was not in right position. Sent from my iPad using Tapatalk
  9. Hi all, I broke the pivot of balance wheel on ETA 2804-2. I bought a generic complete balance wheel with bridge for ETA 2824-2 (http://www.ebay.com/itm/262234041099?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and tried to install it without any difficulty. There is only a difference between the new and old one is the shock assemblies (Incabloc vs Novodiac). In the photo below, the new one is the yeallow on the right hand side. My question are: - Is the complete balance wheel and bridge replaceable between those movements? - If Yes, after installed, the balance wheel has swung a little bit then stop. What is the reason? How to fix it? Thank you
  10. Hi Michael. Thank you for your helpful info. Definitely go to this market and museum also. Sound like heaven vinn Sent from my iPad using Tapatalk
  11. I 'm going to Geneva this month and wondering if there is tools shops especially for oiling over there. I'm looking for decent tools with reasonable price. Sharing information is highly appreciated. Thank you Khoa
  12. I agree with@oldhippy its a snap case back and could be opened by knife blade
  13. I haven't oiled any point. The screw on the lower bridge is tighten with adequate force. Maybe I'll dismantle the transfer and reduction wheels Sent from my iPad using Tapatalk
  14. Hi all, I've got a FC watch which used a SW300.1 movement to repair. The rotor is stuck/stiff and its hard to rotate. I've dissemble self-winding mechanism and oscilating and ball bearing from the movement. As you can see in the video clip, the transfer wheel seems to be stuck when I rotate the rotor. Please give me your suggestion for this case. Should I buy a new ball bearing? Thanks IMG_0047.MOV
