This is the Casio HS-1000. It's a stopwatch with a clock and alarm function. Module 972. Deadstock. With protective seal. The battery has been replaced. The time has been set and the alarm sound has been checked, so you can use it with confidence for a while. Comes with the original strap. This color scheme is classic Casio and looks great. How about it for your collection or everyday use? I am decluttering, so I am selling many items I collected in the past and watches with unconfirmed operation!
