When I recently acquired this watch, there were 3 like it in the database uploaded in 2014 and 2015. Based on the absence of ads and their similarity to the Ambassador line, they were tentatively placed there. I actually thought that's what is was when I purchased it.
Much to my surprise, I found it in the 1955-1957_LineBook_BAWD0127 , Page 35A. The description is overstamped "discontinued". It appears this was offered in 1953 and perhaps 1954. This is the fourth example documented in 7 years and all are dated 1953. It appears quite possible that this model was never advertised and was only around for a very short time.
I really like the "apostrophe" lugs on this one. Yellow gold case and back, silver face. Some high point wear on lugs. Keeping perfect time as received.
