Seiko Sliderule Calculator Chronograph. A pic of the caseback when inquiring about a Seiko will yield info about the month and year of production.
Though real ones exist, these are also heavily faked, especially examples out of India. For more info:

The video states that those with the following serial number are a common but not the only fake: 6N8446
First two numbers are both 2. So i thinking February of 72? What years were they made? Its not fake my dad bought it new at the base overseas and a Japan model . Duane..........Black Diamond, WA. 98010
Does it work? If you shake it for a minute, does it advance and keep time? You would stop / start the chronograph with the top button and reset it with the bottom, do those work? That's the basic check I would do.
Yes. Works and works well. Got the second hand working using the top button however is a little ''sticky'' and i do not want to work too much it before servicing. Still going after 29 hours on a few shakes and a few hours of wearing it. Not very scientific about keeping track, but lost about 15 seconds. So is it super rare,valued,etc? The plastic outer ring is missing. Duane Black Diamond, WA. 98010
