The case back states "10K Rolled Gold Plate" then "Bulova" then "M6" - it is a 1966. I cannot (do not want to - I am an amateur) open the case to see the movement and other markings. I purchased in January 1981 - was told it is a 1954; now I know from the date code that it is a 1966. It is a manual watch. Please note that Roman numerals are used for the hour markers. On 1/18/12 at 12:Noon EDT I attempted to remove back from case and was not able - fear of breaking it.
