The Black Advance Calculator Alarm Stop Watch Quartz NOS is a vintage wristwatch with an analog display. It features a calculator and an alarm, and is designed for unisex adults. The model is Advance and the reference number is /80. The watch is new with tags and has never been worn, making it a deadstock item.

It is not currently working but should just need a new battery as it hasn’t had one in 40 years.

Please see photos. The package does show some wear, such a rare piece of history.
