Cathode Ray Tube Pocket Watch

If you want a unique pocket watch, you can’t beat this one. You will have to be patience though since it takes some time for the CRT to warm up and show you the time.

“The time is displayed on a tiny 3/4” diameter screen at the press of
a button. (Well, you do have to wait 10 seconds for the tube to warm up.)

This watch is powered by a rechargeable NiMH AA battery pack. Battery life
is short when operating the display, so it turns off automatically
after half a minute. The ON time can be extended by pressing the display
button again. “
