Serial dates to OCT 84. 6309-8800. Need to take it down and clean the dial and case... maybe the movement as well. It shows -3 to +2 depending on the position on the time grapher. .4 MS beat error 202ish amplitude. Will probably end up cleaning the movement when I take it apart .... But for the age it runs well.
Going to have to strip the extra crap of the strap... Do not care for that.

Nice. I might consider a lizard strap or nice leather one, or a similar finished bracelet.
