Actually,  that may be more of a problem than you think.  These originally ran on a 1.35V mercury battery.  A 1.5V alkaline cell can overdrive the tuning fork causing the watch to run fast or not at all.  

The watch may be able to be adjusted to work with the modern battery or you need to use an "Accucell" battery.  This is a standard battery that is mounted in a machined brass holder with a dropping diode.

I still have one I bought for around $125 or 150 in Hawail in 1966.  I'm
sure with a fresh battery it wud still work.. I have the see-thru model.
