In reply to Yummy. Thatsa nice watch!! by JP
1934 Ad for gold filled:
1935 ad for gold filled:
We see a Sears 1935 ad Natural Gold plate for same watch. And another 1935 Gold Filled , both in 15 jewels. By 1936 there are ads for a 17 jewel version, but only in natural gold plate.
This Ambassador (in gold fill or gold plate) dissapears from the ads after 1937.
1934 ad here for the dial, but diffent colour so maybe Will's is a re-dial? Looking at the un-numbered sub-dial I would say it is.
EDIT: I would say the inner case seven-digit number is the case s/n, as most of the s/n's, if not all are seven digits, so1934 case s/n.
