This is not on my wrist yet, but it will be later today. So I'll show a file photo of it. Accutron 214 Astronaut from 1964. During a watch exhibit recently, a friend and I consolidated our collections of 24 running Accutron 214 and 218 watches into one cabinet. In a quite room, you could hear them running from 3 feet away!
Yes, it is true. Not all my watches are Omega. This one I purchased a few years back. Had it serviced and added the rubber strap. This is a Wakmann day date.
