We have an old pocket watch at home that belongs to my great grandfather (+1900 1970).
My dad thinks he probably bought arround 1930 but it could always be a gift or something.
It has the name H.C.T. on the dial and on the back there are french lilies. I googled the name but I didn't find anything.
To set the time you have to push a little button on the side. He lived in Belgium if that's any help.
On the last picture you can't see the H.C.T on the dial because of the flash.
