custom watch build . help help with parts

[Sim bal]

hi all

i bought my first automatic watch about 10 years ago ( Ingersoll bison )and apparently it broke only few months after and i was so disappointed that i never used it again . i have a little collection now.

its time to fix it myself .

i opened the watch and found the stem is broken and i lost the crown which had inside threads and the threads on tube are worn out .

yes, my bad perhaps i was careless . 

 

i did some measurements and 

crown is 7mm dia 4.5mm thick with 4.5mm dia internal thread 1.7mm deep of 1 mm pitch and tap size is 9 

the tube is plain 2.5 mm od and 2 mm length where it slips into case and 4.5 mm dia threads 2mm length .

 

any resources as to where can i source these parts ?

thanks in advance

Welcome aboard!  This guy can be a pain to deal with, but he's got parts.  How about some pictures??
