New and in need of advise- Orient 46941

[GioC]

Hello Watchmakers,

I am a total noob when it comes to watchmaking and I am totally fascinated with it that I want to dive into it. I am in need of advice, as well as, guidance. I have my grandfather’s Orient 3 Star caliber 46941 that as far as I know has never been serviced. It is not running, even after wearing it a full day. So I understand that there maybe issues with it and will know more once I disassemble it and clean it; but I want to acquire some items in advance, that may help me on reassembly. One of them is a new mainspring. I understand that new parts for this caliber may not be able to be found and that I may have to buy a donor movement to assist me, but I will like to get a new mainspring for it, this will mean I will have to buy a generic Swiss ETA mainspring replacement. My problem is that I can’t find info onto what that generic Swiss ETA mainspring replacement model/part number is for this Orient movement . I can’t even find the maintenance/repair manual for the caliber 46941. 

Could someone please provide me with some info, point me to the right direction. I would really appreciate it. 

Thank you all for your time.

Gio
