For sale is a very nice example of a 7A28-7079, the world’s first analog quartz chronograph movement. The watch features the 7A28 movement, a 15 jewels, fully serviceable, quartz chronograph movement with an all metal construction. Condition: great condition for vintage watch. Some scratches on the case, bracelet, and clasp. Please inspect the photos. Very nice and clean dial. Some lume damage as pictured. I chose not to have the lume redone. Crystal might be an aftermarket replacement. Dimensions: 40 case diameter, 10mm thickness Functions: sub seconds, chronograph, split seconds timer, 1/10th of a second, hacking seconds Movement: 7A28 quartz, 15 jewels. Movement serviced July 2023. Buttons are a bit sticky, but does not affect chronograph functions. Price: $415 shipped to CONUS. PayPal FF or Zelle ( add 4% for PayPal G&S). Trade: not looking for anything in particular. 34-38 mm in diameter ideally. Colorful dial is a plus. Would also consider any alpinist model with numerals.
