J5, J10, J36 are Alarm pocket watches. They can be identified easily.
On the J5, 21''', the bell ist attached with two srews.
On the J10, 19''', the bell is attached with three screws.
The J36, 19.5''', the bell is attached with three screws but
the alarm set is on the top right corner and not with a pusher.
