Wear OS · Nixie Tube Watch FaceCathode

US$1.99 · One-time purchase · Wear OS 4+

Four glass tubes on a black metal stand light up the hours and minutes. The lit digit glows in front and the unlit digits stay faintly visible behind it, the way nixie tubes look. Two small tubes on top show the day of the month, and the round windows on the left and right start with steps and battery. The time follows your 12 or 24-hour setting.

Pick the tube color on the watch, in Customize. It sets the glow of every digit and the text in the windows. A value with a range, such as battery, draws a thin arc around its number.

Cathode: Nixie Tube Watch Face

Give your Wear OS watch the warm glow of retro nixie tubes, with the time in large glowing digits you can read at a glance. Cathode is a digital nixie tube watch face: four glass tubes on a black metal stand light up the hours and minutes, two small tubes above them show the day of the month, and two round windows on the left and right hold your complications.

Pay once and it's yours: every tube color is included, and it installs straight onto your watch.

LIMITATIONS

What each complication shows (steps, battery, heart rate, weather and so on) comes from your watch and the apps installed on it. If a data source is missing on your watch, choose another one in Customize.
The complications are hidden in always-on mode.
The date tubes show the day of the month only, not the weekday or the month.
Text from complications, such as Steps, follows your watch's language.
Wear OS 3 and older watches cannot install it.
