Rare Nike Sport Chrono H20 100m VD57-5020 Watch Triax Chronograph Vintage Read. This is an extremely rare and hard to find vintage Nike Sport Chrono H20 100m men's watch! It has a brand new battery in it and keeps good time. The top button works good, the bottom button is not working currently. Probably just needs to be cleaned inside. The glass is heavily scratches. The watch case is also heavily worn as shown in the pictures. This would be a great project for someone. Cleaned up this is a very expensive watch. Make sure to view all of the pictures for overall condition.
