Hi all hoping someone can help I've been left two watches. Can't find anything similar on the net. Both on a bangle
Watch 1 marked Royce on the face on the back 68-200 and stamped on the metal bangle Brevet depose which I have found out is french for patent pending.
Watch 2 marked Royce Antichoc on the face and on the back 68-199 also with Brevet depose stamped on the metal bangle.
Are they old? Worth anything? Would hate to take them to the charity shop and see them on antiques road show at a later date lol. Any help would be greatly appreciated. Thank
