I had to look at the forum this was in - I thought it was about a Zenith Defy at first. I can't imagine a smaller one being made, unless it was for a Barbie watch.
Actually I have this one which measures 6 or 7mm signed Omega on the back...it's probably not worth much but it's free to anyone who needs it
