Here is a really odd one that doesn't appear to have been in production very long. A new name for the database with a movement dated 1954 and no date stamp on the case. Case is marked "Bulova Watch Company, Inc." on the outside and "RP Germany" on the inside. Dial is a silver sunburst, like a Bulova 23 with numbers at the even markers and spears at the odd ones. Lume dots at markers with silver hands. Second hand is blued steel.
I found one ad for this one dated 1955 and it appears in the 1955-57 Line book with a notation next to it in pen "1955" and the description is overstamped "discontinued". I found the name as a patent / copyright application dated March 1953. It would appear this one was only produced approx. 1 year.
1954 Saber Jet
It appears that there were several models produced in this shape in 1954/55; multiple variants (A & B confirmed) of a Ladies watch called "Mermaid" as well as this one and a second Men's called "Mastermatic" that had a different dial and was sold on a leather strap. All of them seem to appear in 1954 and disappear in 1955.
Watch runs and appears to keep time.
