2000 Countdown Watch Air cap is unopened. The tape has yellowed due to 26 years of aging. This is a non-sale watch that counts down to the year 2000. I won it as a prize back when Morinaga in Jelly was called Weider in Jelly. It has a heavy stainless steel case. It has been unopened and stored on a bookshelf for many years. It is unknown whether it works. If you are looking for it as a collector's item, please consider it!
