      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 what can went wrong, the movement was functional correctly before..
       
      Thank you for any ideas.
      Mickey

      Hello All,
      I'm wondering what tool is commonly used to manipulate the regulator arm? I've used everything from tweezers to a plastic stick used to help open up computers. My main issue is that all of the things I've used are risky for slippage and I find it incredibly hard to just nudge a little when you're really trying to dial in the timing. I would think there would be a special tool for this (there's a special tool for EVERYTHING), but I haven't managed to find such a tool if it exists. Today I made my own tool using an old broken spring bar tool that I reshaped that should make life a little easier, but I'm very curious to see what everyone else is using.
      thank you

      Hi,
      in order to buy appropriate spares in my attempt to service an Omega 175.0083 (7750)  I need some advice:
      1.
      I've already been suggested to replace MS:
      Barrel is Ok and I'm thinking of buying a new MS and moebius 8217 for barrel lubricating as I don't want to spend money on recommended Kluber 125 grease.
      Should I consider instead buying a barrel complete (assuming Barrel complete (180.1) comes with MS installed) wich supposedly comes prelubricated ?
      2.
      Attached image shows automatic device bridge with evident sign of wear from where, to my understanding, the problem orginated: a screw came off
      I cant find original part. 
      ETA part is different from Omega in that the Omega is larger and partially covers hammer two function and the chronograph cam.
      Beside that and since the watch has no crystal back case I think those parts are perfectly interchangeable.
      Do I need to replace the bridge or are there alternative aproaches to this problem?
      TIA
      Giuseppe

      A new 7750 movement, cleaning and assembly again, why watch swing only 260 °?

    • Does the movement actually need to be removed from the case in order to change the position on the lever or do you just need to unscrew the bezel holding the glass on the front of the case? Perhaps it would be useful to post a pcture of teh watch in its case with the case open.
    • I despise fashion watches. Lets take $10 Chinese quartz movement slap gucci on the dial and sell it for a $1000 Sent from my iPhone using Tapatalk
    • And further to Nucejoe's remark It could be the Cannon Pinion being loose. It slips at calendar change time. When changing the time is the crown really easy to move the hands? Often a sign of a loose CP.
    • Personally, with a screw-down crown like that, I’d just re-use it as is. It may be thread-locked in place.    I always aim to keep them in the inner stem position when removing, but it’s not essential. Gently twist the stem when you insert the new one. 
    • The Bezel might pop off the case when you remove the crystal so be aware. The Bezel might be difficult to fit back to case if the gasket is hard....a little silicone grease might help ease it in. But.....If you support the bezel the crystal will come out  Crystal is 290P02LN03 or 29mm generic glass crystal and you can measure the thickness. crown gasket is DB0055B01 generic is possible 1.75mm or 2.05mm not sure case back gasket is FH2980B02 or generic flat 29.8mm x 0.5mm might be fine try cousins for spares in UK
