Does a 214 not humming with a fresh battery generally mean a bad coil?
Welcome to the forum!
Is this a watch you have had for a while, or a new acquisition? A good cleaning and service may be in order.
Chris Radek, who first answered your question is one of the very well respected Accutron technicians that can service the watch, as well as identify faulty components.
Rob Berkavicius is another well respected Accutron technician.
There are others, but I can highly recommend both Chris and Rob as they have done outstanding work for me in the past.
