Anders has sent us this lovely Lemania chronograph for a service as it’s hardly ticking and the minute recorded hand does not reset to 12.It is a long time since this watch got a service. The grease has turned solid.The silver case has a dent in the side and on instructions from Anders it goes to a local silversmith for repair.There is a little rust damage in some places, but nothing too serious.Almost down to the base movement and you can see plenty of dirt.As it’s a non-shock protected movement the balance cock gets taken apart for cleaning.Here you can see underneath the gear train bridge before cleaning.Some of the gear train visible after removing the bridge.Now I turn the movement around to take out the setting / winding mechanism.Here you can see the old mainspring.I give all the rusty parts a bath in vinegar before rinsing them.The movement being cleaned.Here you can see the watch cleaned and ready to be put back together. Note I have already fitted a new mainspring. The new mainspring has the same dimensions as the old one, but the modern steel is stronger so the movement banked when back together. I was lucky and later found a new old stock mainspring.Balance put back together and I test that it is moving freely.The new old stock mainspring in the barrel.Here you can see the gear train back in place waiting for the train bridge. It all looks much nicer when clean!The base movement is almost back together.Setting mechanism back in place.When I put the balance back in place it starts ticking straight away.After some beat error adjustment the performance is very good!Now I know the movement is not banking I can start putting the chronograph back together.Here you can see the chronograph back together looking really nice! Note: The minute recorder is driven directly from a pinion that engages with the centre wheel.Here you can see the dial side of the movement just before fitting the dial.Unfortunately the sub seconds hand has rusted apart, but I do find a suitable replacement.And now the dial and hands are back in place. The central minutes recorder just needed the tube tightened.Now the movement is back in the case looking and preforming much better than before.The local silver smith did a fair job on filling in the dent. He was instructed not to polish the case.In the case back you can see the Sterling silver hallmarks.Now that is a lovely chronograph!
Hallo
I have a Lemania 2 button chronograph with a CH13 2P movement and I was advised recently that a part is required to get the chronograph function to work.
Do you think you could source a part needed to repair this watch or can you make the part required to get the chronograph working. The watch is running okay.
Thank you
Kind regards
George Evans
As I don’t know what part is needed, I can’t really answer your question..
She’s a beauty!
Beautiful watch and nice repair!
Thanks Mitka for another great job!
The watch performs flawlessly, and with a very nice and crisp chronograph function.
Not a watch to be worn on daily rotation, but a lovely piece of history to enjoy on special occasions.
Lemania cal CH13 was also sold by Omega as cal 28.9CHRO. All designed and made by Lemania, and the first chronograph movement to be designed from scratch to be used in a wristwatch. Earlier designs had been based on pocket chronographs.

Beautiful! what a lovely watch. I can’t believe how well the movement cleaned up. How long do you think it had gone without a service? Looks like decades.
Last service mark in the case lid says “Berlin 53”.
🙂
wow… no wonder the grease was solidified!
Not all watchmakers does “caseback graffiti”, so it could have been serviced also after that, but not unlikely it wasn’t.
Happy to report that Mitka and Christian have ditched that habit!
