Bobbee It looks like the Elizabeth "B" to me. Several Elizabeth ads on site, some are close at lugs. The "B" looks like a match. 1947 ad below. Click for full ad.
The 1955 model lists (below) show 8 occurrences, however note model # 6705 occurs twice- it has a name change from what I think is generic Elizabeth to the "A" variant (same watch, new letter?) . I believe the reason ALL variants are not shown is some sections of the lists only indicate watches w/ recent price changes since previous price lists. After study of price trends in several model series in lists, as cross-checked to ads on site, I believe the $100 "A" and "C" either have diamond dial/bezel or are solid gold. Most likely one of these $100 "B"s also exists but is not in the list.
