Hi & welcome!

Interesting watch, thanx for sharing the pics! With your allowance, I will add them to my HP.
The Rado Watch Co. was registered in January 1937, so we have an earliest date for the production.
To me, only two ladies´ watches are known from 1937 - 1950, both Art Deco style.
This one has a classical dial and hands design, hard to date. I haven´t seen this model before. These dial designs already existed on ladies´ watches in the 1910s, 1920s.
The movement seems to be an AS 970. There´s no shock protection present. Can you find a number/mark under the balance wheel?
What about the mark on the balance bridge? Is it a 3-digit number or 3 letters(that would be a U.S. import code and could identify the importer/maker)?
IMHO the watch is either made 1937 - 1950 or it´s older and the Rado-signed movement is a replacement for an older one. Maybe the mark under the balance wheel brings more info.

Hi!

The scratched marks are marks from watchmakers, who once serviced the watch. This seems to have been done on 12-08-1944 the first time. Normally, a service(cleaning, oiling, adjusting) is to be done after around five years, which would date the purchase of the watch to 1938/39.
So we have a precise dating.
A disasembling by a watchmaker just would deliver the caliber mark of the movement - if it´s on the frontside, under the dial. It can be there, but mustn´t be.
Some of the AS-movements of that time don´t have one.
There´s nearly no info about Schlup & Co., the owner of Rado, from that time. We don´t know when they gave up producing own movements(I know just two Schlup & Co.-signed movements, a pocketwatch- and a ladies´ watch-caliber, look here) and what they did then - producing calibers of other factories in licence or buying ebauches(just part-sets in raw condition), doing the finishing, assembling and adjusting them inhouse(what Rado did up to the 1970s, 1980s AFAIK).
If you want the watch to be worn or just functioning, you should give it to a watchmaker and have it serviced/repaired. If you just want to keep it as keepsake, you can leave it as it is.

Hi!

Hadn´t seen this pic:



There´s a "Swiss" on the dial, so the watch is completely made in Switzerland.
I can´t read the marks on the back, what´s standing there?

Mysterious little thing.
It has "Swiss" on the dial but if the 14k gold case was Swiss, it would wear the official Swiss hallmark for 14 k gold, the squirrel(since 1880) and a responsibility mark for the maker of the case(since 1934).



This back is from a 1950s´ Rado but the marks didn´t change - left to the gold specification the responsibility mark(hammer-head with registraton no.) and right to it the squirrel-hallmark.
If you don´t find these marks on the case, after all it seems to be American with Rado-movement and dial.
