This is my first post. I just received my second Gruen Airflight. This second one flips the hours over at noon - seems to be the usual from searching the 'Net. My first one flips the hours over at 1 pm! To me that makes more sense as noon is 12 hundred hours and it doesn't really need to jump until 1 pm(13:00)...seems odd to think of 12:05 pm as 24:05. IMO it is easier to think of 12:05 am to be 24:05 - anything beyond 23:59 being a new day. I had never given it any thought until I got this other one. Was this a factory special, a modification, or a bungled re-assembly after servicing? I feel stupid for bothering the second seller about it, in my ignorance of what was the usual.
