Coin Silver case has a total weight of 63.8 grams. The hinge for the crystal bezel snaps closed but the hinge is not attached. Condition is good for its age and type with typical scratches nicks dents etc please see photos.
18s OF case with virtually unseen locomotive applied to back in rose gold. Your wheelhouse wants a brute like Rosy here. Front bezel and case back thread on and off as they should. An unusual train and done very well. It may be the only one and will fit many other case centers, and vice versa. Pop in whatever appropriate you have. The engine looks like it means business; perhaps going to pull a Shay out of a deep ditch?
