·Good morning,
I recently acquired a Omega f300Hz, from mid-seventies I believe. Movement 1250.
It was in a reasonable shape, but did not work correctly .. would gain 1h in a period of 3h .. erratically.
It went to my watchmaker who is not a specialist of this kind of movement, does not have the high resolution binoculars but he was able somehow to partially fix it !
Here it is
Now then, today the watch is working but it is not the accuracy one should expect from these movements ( I understand it should be something like 5second shift per month !). Actually, my watch is shifting ahead 15second/day (average). I manage to secure the correct 344 battery (not easy to find overhere).
There is the possibility to tune the movement
It seems you "only" need to turn these 3 prongs devices sitting on top of the serrated "bulb".
The problem is how do you do that ? The bulb can move a little and without an appropriate tool it seems difficult to turn the 3 prongs devices.
What kind of tool should be OK to use ?
Ofcourse I can go back to the watchmaker and that's probably what I'll end up doing ... but I would prefer to adjust myself, the way I do for many other vintage watches I have.
Thank you for your attention,
