There were versions with the correct handstack and many, but not ALL, were eventually dead. I have a version of the original CHS GMTII with a pepsi bezel that still runs fine and also a copy of the CHS GMTIIC that keeps great time. The problem with the newer version I have is a crappy power reserve. When the reserve gets low, say it's been lying on my nightstand for a day or so, it loses time badly. If I were to get it out the watchbox, wind it fully and then wear it for a few days, it keeps near perfect time. Again, crappy power reserve.
