I won a bid for a 10 size Hamilton 917 movement pocket watch on ebay and it finally arrived this morning! Its a plain Jane 917 movement but it works well and I plan to use this as the comparison watch against another 917 which I am in the process of finding. Once I have the second 917 in hand, get it to working order than to begin figuring out what case will fit it as a wrist watch. From what I have been reading, a 44mm case should suffice to fit the movement after some trimming.
Now to find the next 917.
