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.
UG Tri-Compax Chronograph (centre) seconds hand can’t turn past 58.5 seconds and the whole watch stops tickingBy IOB
I have a UG Tri-Compax from the 1950s or 60s (Calibre 281): The chronograph (centre) seconds hand can’t turn past 58.5 seconds and the whole watch stops ticking/working (nothing moving/turning in the movement). However, when the reset pusher (4 o’clock) is kept pressed, it enables the seconds hand and watch to move/tick again. The reset pusher is released when the chrono seconds hand reaches 60: the watch resumes ticking and the hands move until the chrono seconds hand reaches 58.5s again. The process is repeated.
It has been noticed that if the watch is held face down then the reset pusher “procedure” doesn’t always work (i.e. the watch does not resume ticking/moving). It’s usually necessary to turn the watch over and try to press the pusher a few times in order to make the seconds hands move again.
The 30-minute sub-dial at 3 o’clock has stopped working, too.
If the chrono is not activated, then the watch seems to run properly.
What do you think is the problem?
Thanks for your insight!
I want to show you my lately restoration project. This time it was a Seiko 7015-8000 with blue dial. Watch came to me in very poor condition. As you can see on photos the case was scratchty, crystal was totaly tarnished with deep scratches. Everywhere was dirt, gunk and mud...yuck. Movement was running and stopping with very low amplitude. After opened the caseback I wasn't suprised - it looked like as case - dirt and signs of wear. Rotor was loose and fall out the case. When I take off the crystall I saw dial which had faded Seiko logo, some scratches and hands which lost their lume.
Next step was strip down the movement - everywhere dirt and dry old oil. Time to cleaning bath
Look at this - it's my temporary balance wheel stand - I suspect that from temporary it will be permanent. It does job well.
After cleaning it's time to assembly movement. Now it looks better - maybe not pristine but clean and shiny. New oil here and there and movement starts to run. Now it's time for bench testing before install it to the case.
Meanwhile I took care of the case, dial and hands. Case got some polishing work - not to much cause I didn't want to loose the sharpness of edges. That is effect:
Dial and hands got new lume - I am not perfect in this work but I still learn to do this. Additional the seconds hand was repainted to orange color. I didn't change the crystall but i just polished it with waterpaper and on the end polish paste. Effect suprissed me. Time for the pleasant work - putting this all pieces together into the watch.
I started new project - Citizen 67-9119. It's seventies chronograph based on 8110A movement. Watch came to me as "fully working in great condition" As you can see there isn't crystal. The one which was here had chip and wasn't set properly in bezel so when i turned the watch it fall on the floor and broke. As you can see dial is in quite good condition, only it needs to be relumed. Hands needs to be repainted and relumed too. Movement works well but it is too speedy ( +3 min/24h). Chrono buttons work properly, only the hour counter stops at "3h" position so I must to take a look here. I striped down the watch and disassembled movement. There was some much oil everywhere so the cleaning is required.
Sourced on ebay some relatively inexpensive Landeron 3 watch. Looks like 30ties, all original. 40mm diameter without crown.
Watch was sold for parts or repairs. This is all info what I got from seller:
Watch looks very dirty (I will not wonder if that dirt is still from war)...
Balance completely disassembled, but all parts present (in the same box as watch, at least hairspring was in container).
One of the pusher levers is broken (but broken piece is there).
Other pusher was not properly installed (fixed that already).
Foil disc from under dial is also there inside the box.
Dial was not tightened enough, so small register seconds hand was hanging around under scratched glass.
Mainspring was fully wounded.
I don't know what to think about that... I mean, I am a beginner, but at least I wouldn't left wounded mainspring, and probably disassembled balance parts I wouldn't just throw in a box with the watch.
When I look at the balance staff, it doesn't look so bad to me (see the pics and comment please, I might be wrong), so I wonder, why it's disassembled. Could it be, that watch stopped working because of dirt/old oil, and someone unexperienced decided that balance needs to be disassembled?
Any ideas where to start? I was thinking about bringing it to watchmaker to check/assemble the balance, and see if it swings more or less fine, and after that start with cleaning/oiling.
P.S. Does anyone has spare pusher levers for this movement? Or could some laser welding work to fix broken one, or that will not be strong enough?
And any suggestions about hands - should I restore them (blue layer is coming off at some parts) or keep them "patinated" as they are?

Hi Guys I have an international ultrasonic valve driven the machine works ok but the ultrasonic does not, Bought as a project several years ago still waiting to be done. I will post some pics sometime.. As JerseyMo's one is a single valve, get stuck in and have a go, It might make a big bang so power it up in the yard.
