Hi Didier I agree with Chuck. I keep my Accutron on a nightstand beside my bed, and even with my bad ear, I can hear it humming away! The one year life for a battery is about right too. Mercury cells were what they were designed to run on, and since those are no longer available, silver oxide cells are used as replacements. Since the voltage on these is higher, it drives the tuning fork harder and not only are they louder, but they need to be "re-phased" so that they index correctly with the increased amplitude. This has been a topic of much discussion in Accutron circles!

Accutrons eat cells for lunch. You get 1 year and not much more. Remember the one transistor oscillator is cranking 24/7, and the hum is audible if the watch sits on any kind of sounding board. I'd be happy to help. -Chuck Harris Didier Juges wrote: > Chuck, > > My dad has one of the original tuning fork Accutron. I know he stopped > wearing it a while back, but I am not sure why.
