Hello, Ian!
My name is Karsten from Germany. I am a hobby-watchmaker and I think that I can help you. In the 80th Valjoux has sold the production line for the 77XX-Serie to Poljot in Moskau (ex UdSSR). Until now Poljot manufactures Valjoux Caliber under their own name. Russian Watches with Poljot Caliber 3133 you can buy in ebay for approx. 60 USD. I am sure that the stems you can use. Last month I repair a Breitling Chronograph with Poljot parts without any adjustments.
Try it! I hope you can understand my English because it is from school and very poor. Good luck.
Best regards
Karsten

: Hi Everyone,

: I have a Vintage Monaco Manual Valjoux 7736 for
: which I require the inner and outer stems.
: My watchmaker says that the thread is
: "tap 12" (whatever that is!). This
: part will probably be common to all Heuers
: which use this movement.

: Does anybody have an idea where I can get my
: hands on these parts (we have an order on
: Tag for a few months without luck).

: Any help would be greatly appreciated.

: Thanks,
: Ian
