Ive got this antique pocket watch here and I would like to add s secoubd hand to the little subsection here. I've hot the replacement hands of various sizes I believe I need a size 12 and the lot I purchased has them. In order to even do that i need to access the dial and i wanna do it right as to not damage anything, it appears thst I can either open up yhe front or pull out the whole movement from the back. I can't even see weather or not the pinion is still intact cuz its smell snd dark in there but im hopeinf I can get this secound hand on there. Any advice on how to get this opened up or how to get the hand on the pinion. It dosent seem to twist off on the front there's no front hinge so I think it needs to be pried off at this lip here.
