JLC Memovox Service


Recommended Posts

Hello fellow watch repairers,

 

a few days before christmas I scrolled through a website for used stuff and came across an unbelievable offer for a vintage JLC Memovox for just under 1000€. It said that the dial was restored but for this price I just couldn’t say no to it, although I feared that it might be a scam. So on the twenty-third of December I drove four hours to pick it up, still with the feeling that it is to good to be true. But everything worked out well and I bought the watch what makes me the proud owner of my first JLC:

And with a new strap it was a really lovely piece:23FF9F97-A9F5-43CE-9FC9-6B2E92C3D139.thumb.jpeg.4e864f035ec1fa29ea971470fd68542c.jpeg

At first everything worked well but after a few days the alarm wasn’t functioning anymore. Diagnosis: broken alarm mainspring. So I had to replace it and give the whole movement a service.

The movement itself seemed to be in good condition and marks in the caseback showed that it was at least serviced a couple of times during its lifetime:

Here a some impressions from the stripdown:

And indeed the alarm mainspring was broken:

I cleaned all the parts, replaced the spring and reassembled it. Now the alarm works flawlessly again, it is running nicely and is ready for its next life chapter.

I never worked on such a valuable and complicated watch, so I‘m really happy that everything went well and that the watch is working again. 

I hope you enjoyed this short report!
