Sold to me as 1960s..
Thanks.. I came by the movement ID as found 64 just next to the balance wheel and did the search for that number..Nice dial and crystal. This must have been one of their higher end watches due to the case numbering and dial.
While the crystal fits the watch I wonder if it is original. I assume it is a high acrylic and would be relatively rare in the latter 50's and earlier 60's when the movement was in use by makers... (assuming your movement id is correct ).
