I have my Chronosport UDT for sale right now on eBay. I originally purchased it 1986. I saw the watch on GQ I think. I lived in NY and drove to CT and got it at a dive shop. That shop in CT actually serviced it for me when I lived there. They were using Chronoserv I think. I've been gentle with the watch because it was my only nice watch. I don't spend lots of money on watches nor jewelry so I took good care of it.
Please check it out on eBay of you are interested. The auction ends Apr 24, 2013
