I have this Hampden a few years now.
From my quick research:
1. Hunter movement in a open face case
2. Movement was made 1885 approx
3. Possibly 17 jewels?
The minute hand looks odd in context to the hour hand, is this hand original ?
The hand is slightly bent as well.
I intend to get the watch serviced and cleaned next year as I am unable to set the time when I pull the stem out. When I turn the stem the hands won't move.
I can wind it no problem and the movement is working fine.
Any more information would be appreciated.
