-1970 Bulova Accutron Astronaut Mark II 'B'
Case is 14K gold filled, case# 2992, dated N0; dial looks to be an aged silver with yellow gold accents, calendar window, luminous; 2185 tuning fork movement, USA-made, dated N0; top crown moves the hour hand to local time, red hand is set to home time; NOS Accutron corfam strap added.
There look to be two versions of the yellow gold style (similar to the 'A' variant in SS); the 'B' appears to be the strap option, the 'F' appears to be a gold bracelet option. Since I do not have the original band, thinking the logical option would be the B var.
