Service H. Moser & Cie/Calibre FEF 100

Hans Moser & cieThis little men’s watch is truly a rare beauty made by H. Moser & Cie with an unusual Fleurier caliber 100. The watch is running but the timegrapher can’t pick up the signal.IMG_0754The finish is a little rough for modern standards but considering this watch is from the 1920’s-1930’s it has a very unusual and complex designIMG_0755The case design is also very special and the logo is stamped in the case back.IMG_0752The movement looks fairly nice and clean.IMG_0757Some nice perlage decoration on the bottom plate.IMG_0759Coming apart without any problems and soon ready for the cleaning machine.IMG_0816While reassembling the movement the hairspring stud fell out leaving me with a real challenge.IMG_0817I lost the pin, so I made a new one on the lathe.IMG_0818After some tinkering I manage to attach the stud back on to the hairspring and we are back in business.IMG_0828 The movement back together and in the case.IMG_0826Nice performance.IMG_0832I polish the hour and minute hand and replace the non-original sub second hand with one that matches the other hands. I really like the design of this watch.

  1. Hey Mitka, you are getting nice watches to service for your practice…I wonder where you get hold of them?

    And I wonder when are you going to start on your first customer’s watch?

  2. very nice job! Mitka any advice about polishing hands? hands are very fragile and easy to bend… how you do it?

    • You use a very soft but firm rag. The ones you polish glasses with are suitable. Then you apply polishing paste to the rag. You then hold the hand down with your finger so it dose not bend and polish in one direction over the paste and then over a clean surface of the rag to get rid of the paste. It is a delicate procedure and be careful that you don’t over do it and polish gilding away. Some times you got to stop before ruining the hands. Good luck and take it easy with those hands;)

  3. Love that dial, and polished copper coloured hands. I’m curious what make of lathe that is? I’d be interested to see a “walk around” of the workshop and tools, and perhaps tips on what to buy and what to avoid when buying used equipment. I know it’s a lot to ask.

  4. Interesting watch!
    I have read somewhere that the company had their main business in Russia prior to the revolution in 1918, and that the Russian subsidiary was confiscated by the communists in 1920. Is this a early Soviet watch?
    I am only guessing but it has no “swiss made” markings?
    The current line-up (the brand was resurrected in 2002) looks quite interesting as well!

    • Hi Anders

      Thank you for the interesting info. I have not found any swiss made markings nor any hammer and sickle for that matter. The movement is swiss
