It contains a perpetual calendar movement (caliber 8F35) that’s accurate to 20 seconds per year due to a high frequency oscillator that boogies at 196KHz with 4 jewels. Very good condition with little to no obvious signs of wear. The bracelet clasp is signed Seiko but it is not the original of this model. No box/paper/tags. This was a pretty high end watch and a less common model find. The 8F family movements were consider some of Seiko's best. The watch has not been used for a long of time and it has not been tested. It need a new battery and the perpetual calendar needs to be set. For setting instructions you can check the Youtube video on how to reset it, but any watchmaker can properly change the battery when it indicates it is running low by skipping seconds to avoid the reset.
