SEIKO QUARTZ MULTI-ALARM Watch Battery replaced, operation confirmed. The small light bulb also works perfectly. This is a SEIKO digital watch from around the 80s. The segment arrangement, the function display in the upper left, and the buttons on the front are retro-future and very cool. I believe it's rare to find a fully functional one. There are signs of use, scratches, and marks. The left button has a quirk. The wrist size can be adjusted with the clasp.
