11BLC Split Stem

Looking for a split stem assembly for an 11BLC movement as you can see from this photo it is pretty oxidized and there is a lot of play in the stem.

Does anyone know what other movements 11BLC might cross with to find a similar part?

Hi MGD001 ,  I have attached a page from Ranfft movements that show other 11 Bxx calibers in the same family . But since this is a split stem I am assuming your movement is from a front loading case . That is where the movement is removed from the dial side after the crystal is removed .

  If that is the case then you have to seek a split stem for this series movement as there is usually a solid and split stem version for the same movement . 

It is easy enough to find the threaded side in male and female configurations and in different thread tap sizes,....I just bought an assortment of 12 in tap 8 and 10 , male and female . You are concerened with getting the proper movement side stem .

  If I find something I will post it .....Good Luck with your search

  You might want to send an inquiry to Sudarson of OLD SWISS WATCHES . I saw that he has some movement parts listed for the Bulova 11 Axxx and 11 Bxxx series . I have been lucky a few times looking for parts that weren't listed or shown on the web page .
