Waltham ID

I need to order a new balance staff for this Waltham.  I was able to look up serial # to date it to 1919 but could not find the caliber.  Is this a split stem?  Front load?  Thanks.

the watch is basically a tiny pocket watch. Pull crown out to setting take the two case screws out and whatever bezel is on the front the movement should go out the front.

then you go in the pocket watch database at the link below and not as helpful as it normally would be. So we find out the grade but that's not really important missing is the model number 1907 that is more important. Then there is no parts listing which is interesting because it is in the parts book they does haven't got it into their database yet. So I'm attaching the parts listing.

classic problem with American pocket watch staffs you won't bill order wanted to you take the old one out. Jesse can see what the problem is I've attached staffing information.  then as a reminder this is a friction staff. Usually there's a blue steel hub to warn you about this but it's not always blue. So it makes it a lot easier to change if you know what you're doing.
