Good looking Seiko A159-5009 of 1977. One of the first models of Digital watch with Alarm and Chronometer. Everything works normally as it should, It has a backlight functioning as well. I have bought this Seiko A159, 2 years ago .. I cleaned it in a ultrasonic bath (all components, except the what should not goes in the ultrasonic), I put new pushbutton's gaskets! (the old one were 40years old and hardened), I found nicer pushbuttons that are not that corroded (on other models of A159 that I bought later on). I put a new crystal (glass). Now, the crystal is new and has no scratch. The bracelet is original and it has all the extra links! It can fit an extra larger wrist. The battery hatch is still in a fairly good condition and its gasket has been lubricated.
