  1. dennisondik Jun 11, 2021

    Please help if you can. I am in need of a female stem part for a Seamaster cosmic case 166.023 movement 565. I need a 10 tap (.090mm) thread. I the broken ones Non-threaded part is 1.20 mm diameter and 1.85 mm long. According to CasKer a bestfit 360-344 is suppose to work. I see that there are 2 omega parts but I 081ST9992 and 081ST9993. I don't have the dimensions for the non threaded part so I am not sure if these can work or not.. Can you Help?
