Introduction

The Cathode Corner Nixie Watch is just about the most unusual yet
practical timepiece you can wear on your wrist. It is a two-digit nixie
tube wristwatch designed for everyday use. It’s guaranteed to get
attention. People will ask you, “What is that? Is it a watch? Show me

no button pushing to operate – it shows the hours, minutes and
seconds in sequence at the flick of the wrist. It provides a bit of
theater with every reading.

The large round crystal shows off the workings of the watch: the
tubes, battery, high-voltage power supply and setting controls are all
visible.

The watch features 12 or 24-hour time display mode, user-settable tilt
angle, and easy time setting operation. The timekeeping rate is
adjustable and the watch comes pre-adjusted to within a few seconds
a week.

The two Nixie tubes are the widely available B-5870 type and are
socketed for easy replacement in case of damage. These tubes have

0.6” (14mm) tall digits for easy reading in adverse conditions.

Opening the case by unscrewing the ribbed cover reveals the time
setting buttons, the battery and the tubes. For the hardcore code
hacker, a programming adapter allows the open-source PIC software
running the watch to be changed at will.

The case is made of strong, lightweight aircraft aluminum, hard
anodized for lasting beauty. The rear of the case is gently contoured
for comfort in all-day use. An O-ring seal keeps out water, dust and
