Ya gotta figure, If I carried it for my daily time it will be dead nuts accurate. Right now I am carrying my 992B early 40's. I do shutter as if I break it ... oh boy .. but I never seen anything like it time wise. My uncle was a fighter pilot in WWII. He said even though they had top notch wrist watches that they were given, the pilots would only bet their life on the 992B. Good enough for them, good enough for me
