Nice collection. It is quite unusual to see clocks, they are less sought after than the watches.
Here is a 1925 catalog page that shows a travel clock that looks similar to one in Cristos' collection (second picture of his original post), showing also the original luminous hands :
Mine doesn't have a small second sub-dial:
In the 1930 catalog, the second one on that page looks similar to one of cristos' collection (same dial and hands):
Two other models from the same 1930 catalog :
I also have a 1928 catalog dedicated to clocks, which I post here if you have interest in those :
Nothing on alarm clocks, clocks from the fifties or, sadly, on dead second ones.
