My first post in this forum--hoping someone can help me finish a project watch I picked up on eBay about a month ago.
The movement is a "11ACC" which according to the pink pages a derivative of the 10BOAC.
I've been able to get the movement running acceptably by just giving it a good service (cleaning and lubrication). Was able to reuse the mainspring as well. From what I can tell, the watch had never been serviced, so pretty happy with how that went.
Next challenge is reassembling it with a new crystal and proper crown. I should be able to get a standard GS crystal for this watch from one of the US supply houses. However having trouble making out where to secure the male 1/2 with crown the two-piece stem--this is where I can use some help. If anyone on the forum knows the proper part number and/or where I can score one please PM me.
Thanks in advance!
