I do not see one of these shown in this forum. They are next best case for an 18 or 16 size movement than an original gold in my opinion. Available to watch dealers, not generally, although many made before and after 1900 were used as travel clocks. Not rare but hard to find in unused condition. Bought this one, sellers fuzzy photos, since a good condition example. Used to be more commonly available so also not now a cheap item. This one has an age appropriate good 83 model movement.
