  1. First of all my apologies for not having documented the disassembling, but the watch arrived in a terrible condition and I stripped it down right away to get rid of all that dirt. If you have worked on some watches yet and think about entering the chronograph world with a 7734 let me give you 3 advices: Do it! The 7734 is a solid construction and not too complicated. Take your time and watch all the 6 parts of Mark's Venus 175-service on youtube. Of course the Venus is a column wheel system, but the basic movement is very similar and also on the chrono layer you can le
  2. My first time servicing a 7758. Started to open the mainspring arbor and was surprised to find what appears to be a small gear affixed (permanently?) to the bottom end of the arbor. Feels like some kind of Teflon material. I assume it drives the moon phase wheel? Any help here would be greatly appreciated. Not sure how to proceed since if it isn't supposed to be removed from the arbor I'm not sure how to deal with the spring.
  3. Hello, everybody. I wanted to share my restoration stories that I have done for a long time and thrown into my archive. First I discussed the Atomic Mars 71 Brand using Valjoux 7734. As it was seen, scratch and dial is broken. To begin with, I tried to brush the Case as Brushed and make it the first day. If it is decorated, I polished and re-painted the indexes (with acrylic paint). I usually do this in three layers so that the paint is not deleted in a short time. I replaced the case buttons and tubes with aftermarket buttons. Since the condition of the dial was in ver
  4. Hello everyone. I have a really sad story and I am a complete amateur. I am a machinist for a living so I thought I would give a crack at making a frankenwatch, however it did not go as planned and now I have a movement with subdials that don’t work and a whole lot of parts and money invested and I don’t know what to do. I need the help of a professional. The donor movement was a NOS, new old stock, and was running perfectly, however I messed up almost everything attempting to make this watch. I will happily ship all of the parts needed to complete this watch and pay for any repair that need t
  5. Hello, I'm new here and into watch/horology world as well. I recently tried to replace the dial on my 7750 watch. 1) Open the wathc case 2) removed rotor 3) removed stem (gentle push of remove stem pusher and pull the stem out) 4) removed the movement from the case 5) put movment to movement holder 6) removed hands 7) removed dial 8) put new dial 9) pressed the hands back, hovewer during setting it up I realized the movement is not running - even when I wind it up - it is solid/stable and not ticking at all.. Kind of out of ideas w
  6. Hi everyone! I'm J from USA. Could anyone please help and instruct me on the best way to set my Valjoux 72C? I have a Ref 6036 and don't want to ruin it! Thanks in advance!
  7. Hi everyone, Thanks in advance for your patience- novice here! The chronograph function on this 7730 movement starts fine but doesn't stop reliably (If and when the operating lever does engage the stop, the reset works great, however). When I open up the movement case back, I see that operating lever (blue arrow on the annotated stock picture) has a bit of play and moves around, such that if I do engage the operating lever, i.e., begin the chronograph, and then gently push the reset button , the reset lever (red arrow in diagram) 'nudges' the operating lever back into the correct p
  8. Hello guys.. I wanna ask.. How to adjust my eta valjoux 7750 movement to be faster.. Cause it slow 2-3 minute a day.. Do i just need to move this part to the (+) sign?? Thankyouu
  9. Hello again gents, I have a question about Valjoux 72 hairspring , what Is the identical part to fit this cal? I only need the hairspring due to I slip during regulating the beat and it can't be properly restore.
  10. Hi, Can anyone point me in the right direction to where I can economically buy a Valjoux ETA 7751 movement, dial, hands, day/date and moon phase dials? I am based in the U.K.
  11. Hallo and congratulation for this forum and interesting Watch Repair Talk's clips. Could anyone show or tell how to regulate a Valjoux 7550? I noticed that there are two versions: one simplier with two arms (one with two dots) and another one more complicated (unfortunately mine) in which there is a ring with an arrow which points to + - like in the picture below. In this case, should one move the edge of the arrow or is anything to be unlocked before doing that, or where does one have to touch/push in order to move the arrow towards + or - ? Many thanks
  12. As per the title, I was checking why my Gigandet Valjoux 7733- based chrono was not working today, and noticed that the hair spring got loose from the small insert that connects it to the balance cock (what's its name again?) Taking a closer look, it appeared to have been fixed with schellac, but I am not sure. Would this be normal, if so? So now I need to find a way to reinstall the hair spring inside the stud. Heating it gently could be the way, but I am afraid I will only riun the hair spring if not careful enough... Ideas? Comments?
  13. So today I received the set of spare Landeron movements I had bought last week. I received some spares, and 4 incomplete movements, various models, and a dial. Movements are completely dirty, will definitively need a good clean on my Elma, and the dial has also some patina, which actually I like. Here the pics: A very fast clean (by no means to make it working perfectly) and I put some parts together with the best looking movement, to have a working watch. I do not have proper cases for the chronographs as of yet, but I am still looking.
