Can anyone identify the maker?

Of the watch in this appalling photograph?



It's thought to be roughly 1930s

Any help would be ace.

I have something that looks sort-of-similar on an old Eterna (pre ETA) actioned Rado.

Pocket watch movements have a tendency to look similar to one another but I have a 1920s Waltham which is identical in layout to that one (although mine has some nice decorative engraving on it).

Photo maybe slightly misleading. It's a ladies dress watch, case is about an inch across.

OK, still could be, or Cortebert (who supplied movements to Rolex, among others).
