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..
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.
in order to buy appropriate spares in my attempt to service an Omega 175.0083 (7750) I need some advice:
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 ?
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?
I just grabbed this 1971 vintage Seiko Lord-Matic. It was being sold as a non-runner, hopefully nothing is actually broken. I'd like to replace the Crystal, but it looks like there isn't a direct replacement currently available on the internet. At the very least the dial needs some attention with some kind of stain around the day window. Updates will follow as soon as it arrives.
Hey, bit late to the party but I use the Elma 1:9 too.
I have spent a lot of time trialing different strategies for cleaning parts. The best I have come up with is Elma 1:9 in an ultrasonic at about 40C for 4 minutes, then rinsing the parts basket in distilled water at 40-50C twice, the second time in the ultrasonic. For some but not all parts I use pure Isopropyl alcohol as a final rinse.
I have a gallon of the Suprol rinse here doing nothing but posing a fire hazard. Because I hate the smell of it and also, no matter what I tried it would leave some residue on the parts after drying.
I have an Elma S10, non heated ultrasonic cleaner, it works very well. I just run my tap to get the water temperature right, and considering the short cleaning times the water doesn't cool down much.
Could you please help me with the crown? I have these buttons, but what does that 9/24, 9/28 etc means? 9 or 8 are the thread size right? 9 is 0.9mm? But what is /24 and /28 and /30? Would that be 2.4 2.8 and 3 mm? I tried to compare a 9/24 to a 9/30 but the 9/30 does not seem to be bigger in any dimension? Not even sure if the right sized buttons are in the right container. I am trying to find a silver button for the silver case. Would be nice to know how the original looked like.
