For a real battery eating watch, Google "Nixie watch".

Are Nixie tubes the neon tubes that had a stack of electrodes in the
shape of the digits 0-9? If so, I'm amazed that those could be made
small enough and thin enough to fit four of them (HH:MM) into a watch.

They are a bit bulky and I don't think anyone made such watches at the
time, but they have become popular "steampunk" items. There are
definitely 4-digit ones available.
