Service: Lemania calibre 3615

P1070530

This Lemania calibre 3615 is not running and in need of a good service. These are very unusual and I have wanted to work on one for quite some time. 

P1070531

Movement looks to be in good condition.

P1090164

The Dial is in excellent condition. The case is really beaten and will be sent away for a polish as it’s letting the watch down.

P1090166

With the dial removed you can see the date mechanism. 

P1090168

Here you can see the setting/winding mechanism.

P1090169

I start taking apart the autowinder mechanism. 

P1090170

The ratchet wheel acts like giant a reverser wheel. 

P1090173

Plenty of dirt lying around in the movement.

P1090174

Here you can see the gear train layout.

P1090175

Old mainspring in the barrel.

P1090263

Movement is cleaned and looks a lot better!

P1090265

I see that the balance moves freely after fitting the shock jewels.

P1090264

The old mainspring is cleaned, oiled and goes back into the barrel.

P1090266

Here you can see the base movement coming together.

P1090267

The setting/winding mechanism. The original crown has been re-plated rose gold as the old gold plating was worn.

P1090268

Ratchet wheel spring that is sandwiched between the two ratchet wheels.

P1090270

Movement coming back together.

 

P1090272

With the date mechanism back in place and the movement is ready for dial and hands.

P1090273

Very nice original dial! 

P1090274

I fit the movement into the case.

P1090271

I’m very happy with the performance. 

P1090275

Very funky movement! 

P1090279

I usually don’t have watch cases polished, but this time it was really worth it! 

P1090289

Very close to being the perfect watch in my book!

    Very very nice! And as much as I don’t like the over used word ‘rare’ this must surely be up there with unicorns!?!
    Does this movement pop up anywhere else as an ebauche do you know?
