  1. Thank you. How to determine if the Mainspring is coated? But anyway if it's an old mainspring then it's better to clean and lubricate it with some oil right?
  2. A stupid question but lately I heard some people said you can leave the mainspring clean and dry. Just set it back to the barrel it will function just fine. The reason for that is when it's wind-up the spring wont touch each other (I doubt that) so no fiction and thus no need to lubricate the mainspring. Any opinion?

  4. Thank you so much! These are very helpful informations.
  5. Hey guys. I'm finding technical sheets of the following seiko movement: 5740C and 4s28. If you know where I can access to these files, please let me know. BTW I'm planing to sort of 'DIY' a wrist watch use these two movement and dial strip down from pocket watches. If you had work on any of these movement, please leave a message I‘ll contact you privately if that‘s OK. Thank you guys. Peace
  6. So normally if you want to disassemble a Swatch SW626SW you just pull the stem out just like pulling out the canon pinion. But the swatch I'm currently working at is a stubborn one. Its stem stucked. So the stem can not rotate can not pull out and set time. I haven'e try to force the stem put cuz I worry about the consequences. If there any better way to deal with it?
  7. Hey. I have a walk through about this movement. Check this And the cap jewel of the escape wheel can be taken of. you just need to use a tweezer and turn it just like how you deal with seiko diashock jewels and if can fall of. As for the lurbrication, you can check my walkthrough.
  8. Hi. Just wanna know how much you take to buy that movement. Basically, these movement only cost you about 100~200RMB which is around 10~20€, so it's possible to have this type of shit. And buyers in China also knows the risk of it. No so sure where do you get this one, so if this happened inside China, the seller normally sent you another hour wheel and canon pinion.
  9. I'm dealing with a citizen movement with a broken barrel arbor. The movement is citizen 6302A21J. The movement and its parts are all obselited. No NOS parts are seen on the market. I'm trying to find some alternative arbor. Maybe some arbor from other movement I can use it and modify it to suit this movement. Here's some measurements about the arbor.'
  10. I find that oil the escape wheel teeth when lurbricating with 9415 is easier to control the amount of grease.
  11. Some Update. I take the movement out without dial and hands and hour wheel. It runs pretty good and stop after 40+ hours. There's only half turn of the mainspring remain to be release, I think that's pretty normal. So I adjusted the hands make sure they dont touch each other and casing it once again. We'll see how far this time the watch can run. One thing I noticed is that although the amplitude doesnt change in the case or out the case, the rate is significantly different. In the case the rate is losing a bit and the positional variation is bigger.
  12. Update: I take the movement out and fully wind it up. I'm check how far this time it can run. If it can be constantly running and graduatly release all the power of the mainspring, then guess the problem is the hands and case
  13. base on how smooth it takes to set time. I dont think canon pinion is the problem.
  14. Hmmm just a guess. The second wheel is fine. Before the movement stop the hands doesn't run like crazy. So it should be something concerning the winding and mainspring barrel.
