Stem and crown for a Valjoux 9

Recommended Posts

Hello all, I have been struggling to find a replacement stem and crown for a pocket chronograph that I have running a valjoux 9 movement.  Since the piece did not come with one to begin with, I don't have the stem measurements.  If anyone has any suggestions for me I would greatly appreciate it.  The outer measurement of the crown tube is 8mm and it is supposed to have a pusher type crown that has a button in the center to activate the chronograph.

I don't know the answer here but wanted to mention that most members consider polite to use the dedicated section to introduce oneself before asking questions.

Hello,

I didn't work on such a movement yet, but at Ranfft it looks like the Valjoux 9 is a member of the Valjoux 5 family and may have the same stem W1730.

There is a seller in germany who has it on his list:

Hope this helps a bit.

    • H.Nathan and co where part of a group of companies owned by the Australian company called Hoffnung and Co their buisness was primarily based around the importing and sale of goods through catalogue they where importers among other things of sewing machines and parts, and Swiss and American watches and all forms of gold and silver jewellery and display cases for retail jewellers. They where a very large concern and supplied goods in Australia, New Zealand and Tasmania , Fiji and Honolulu and had huge warehouses across Australia. H.Nathan and Co was the company's London based subsiduary they where responsible for purchasing goods in Europe and America and arranging the importation to Australia they would have been responsible for the purchasing and importation of your watch, they would not have been the manufacturer of your watch as such but would have sourced them from manufacturers in Switzerland and stamped them with the company name, the earliest reference to Hoffnung and co I can Find is 1872. I think they would have been the Australian equivalent of Sear's Roebuck catalogue in America.
    • Can you post the link and I'll try and help you.
    • Yes that is correct. Looking at this photo you can see which strike side would operate the hammers. They would also need the springs to be the right force to run together, to compensate this the two hammers are lighter than the single one.
    • Some useful sites in case you havn,t visited so far. Julesborel.com Eternaltools.com OldSwissWatches.com Most recommended source is cousinesuk. Yes manufacturers recommend routine M/S replacement. Manual winding gives you an idea how well the spring feels, to say the least eliminates selfwinding mech form diagnostic guestimation. Joe  
    • Can anyone explain why there are 3 winding barrels to achieve this? Are there 2 separate striking trains?
