Citizen 6501 movement

Today's watch is one of my older watches, being older than me!

This is a Citizen automatic watch from the 1970s, and one of the more expensive watches from the era (behind the HiSonic).

It is a 3 hand dial design with a day and date at the 3 o'clock position. The glass is cut in a way to give a flat square in the middle and a cross shape across the face. The case is heavy stainless steel design with a matching steel strap.

The movement is a 6501 which is a 21 jewel automatic movement which Citizen released in 1971. The 6501 movement is one of the Citizen sweep hand designs and runs at 21,600 beats per hour. Online discussions suggest that the 6xxx movements were among the last of the Citizen pre-quartz automatic movements, but the 6501 wasn't produced for very long as Citizen focused on other movements. 

This particular model has a number on the back of 4-651979 and on the face is the number 655505. I'm not sure why the numbers differ between the face and back, but many of the models I've seen are that way, and so I don't know which is actually the model number. The 65xx models had a sale price between ¥14,500 and ¥38,000, but I don't know which end of the scale this is from.
