Casio Digital Databank DB56W

Unbelievable Battery Life - CR2016, that is not even the thick 2032 but a thin battery, lasted over 10 years in this Caliber!
Quite unbelievable. The watch was in the safe for almost 8 years, then around Easter 2002 I took all those watches out and brought them to Thailand. The watch kept running and running until August 2004! This chip is not thirsty at all. The watch has a back light too! Makes this even more magic! I had not used the watch often, but I remember having it worn in 1993 and 1994 quite often because I liked its functions. When stopping time e.g., the upper display would still display the time. I always liked this function on digital watches.
