If the lugs are fixed like at your watch it is likely from the beginning of this periode. If it has a steel case, more likely from the end of the periode. But both is not sure; high grade watches got stainless cases earlier, low grade watches had even later no spring bars.
It has a high grade movement and an all steel case (no chromed top). Moreover on the movement a Patent from 1932 is mentioned, which is missing on later samples of this movement calibre. So it is more likely from 1935, but I still can't be sure.
