It just so happens that I have a GRC-26 manual with a picture of said 
clock. I also have one in my MSC-37 communications shelter (see QRZ 
page). I researched them and they are an 8 day non electroluminesent 
chronograph. I found one and had a friend make a metal case for it. It's 
the same clock that we had in the F-15's. I don't remember the 
manufacturer off the top of my head right now, but can look it up. I can 
also offer pics and a national stock number from the shelter manual. I 
also have the newer model in my S-250 shelter that ran on 1 AA battery. 
Hope this helps.

My friend Joe W3GMS spent many hours operating the radio in the shelter while in the Army back in the 70s seems to remember it was mounted on the wall, had a metal case and was square.  He says he would like to try to get one of those clocks.
