Additional Information

Movement date code M9, visible in a photograph to be submitted.

11/16" strap lugs.  18 mm is a tight fit and workable; 17 mm is a bit loose.  Case is approx. 32.5 mm diameter across the two horizontal corners.

Dial is inscribed "Automatic", as opposed to "Self Winding" which I saw on some earlier examples of this design.

Back is inscribed only with Bulova, the case ser. #, date code N0, and "stainless steel case".  Earlier examples on MyBulova indicate waterproof, anti magnetic, and shock resistant.  I am certain these features are present in this watch - though the standard for "waterproof" at the time was far more loosely defined than it is now.  I expect the requirements for back engraving were changed somewhere between 1968-1970, causing the change to what is seen here.

Nice looking watch and a real style standout of the era. The changes from classifying "waterproof" and "self winding" to automatic and water resistant both occurred in the late 1960's.

Your watch appears to be a 30 jewel

Post 1970, this case and movement were also used in the Sea King line. It appears the determination was face design. The Sea King had a horizontal stripe on it as well as different hour markers.

1970 Bulova Commander AO looks to be a good match to me.  I also believe they used this same case with an adjustable scrolling calendar on a stretch bracelet and called it a Time Center.
