If it’s a Lemania, it has to be Anders’ watch! And so it is …
He’s sent it in for a service, so onto the timegrapher to see what it’s doing.
Yes, indeed. Low amplitude, large beat error, and too fast.
The movement does look clean, but there is no more oil left, and that explains the low amplitude. Note the little bridge with the two jewels holding the third wheel and the second pinion. Very nicely executed, so you press on the second hand without having to support the pinion from behind.
A very clean bottom plate in great condition.
I start taking the movement apart.
The keyless works have a bit of solidified grease and dirt on them, but it would be unusual not to find that.
All the parts go into the cleaning machine.
With a new mainspring, I put the movement back together.
The balance back in and ticking. The regulator only sits on top of the hairspring and holds it from above, without a boot that has to be closed around the hairspring. Saves a bit of time when removing the cock to adjust the beat error.
Which is necessary. 4.3ms is a bit too much even for a collet adjusted movement.
So out comes the balance, and I slightly turn the collet. I previously marked the direction and angle on the watch paper.
And back onto the timegrapher.
Great amplitude, and I’m happy with a beat error of 2ms.
Now I can put the bottom plate back together. Note that the decoration and design looks exactly like on an Omega movement, and there are good reasons for that. A fair amount of Omega movements were developed by Lemania.
The case didn’t have a gasket, so I put in a new one with a bit of silicone grease.And back together. The little white dirt spot is luckily on top of the crystal 😉
Hi,
Great post!
Im on the hunt for a hairspring for my cali 3060 Lemania, however it seems hard to find. Do you know any store that sell it for a reasonable price and or could I buy another hairspring that would fit with my watch?
Thanks in advance,
Your only chance will be a donor movement.
Mmmm..lovely shine on those bridges! Looks like a really intelligently designed movement.
It’s good to have some more articles, I was beginning to get worried! Hope everything’s well Christian.

Wow – glossy 😉
This one is actually a very early “divers watch”. The caseback on this one shows the EPSA Super Compressor marks. The engraving 1-61 inside the case is actually the production month and date, so January 1961 the case was made by EPSA – Ervin Piquerez S.A in Switzerland.
For those interested there are more info here:

I do not intend to take it for a swim, and absolutely not for a dive!
Looks great Christian!
Thank you!
