I purchased a $25 bag of watches that contained 6 watches. The best was a Gruen, Timex Snoopy Tennis watch and this awesome condition Bulova 23. The case is a mono case front loader so I did not open it. I am assuming the movement is the standard 10BZAC 23J movement. the dial is a gorgeous silver sunburst with full lumed hour markers and hands. I especially love the notches in the bezel. Found it in the 1961 Line book Bulova 23 "RAW".
