Cathode: Nixie Clock

A nixie-tube clock for your wrist, drawn as a crisp flat graphic. Four glass tubes glow with bent-wire digits in your color, and when the minute changes every tube that changes flashes through its cathodes as the new digit lights up. FEATURES • Flat nixie tubes with the faint unlit cathodes behind the lit digit • A cathode flash and soft re-light at every minute change; perfectly still in between • Six complication slots, each with useful built-in data underneath, so nothing is ever empty • Weather on top and the date on a label plate (three formats) • A single-digit hour drops the leading tube and re-centers the clock DATA SHOWN • The weather now with today's high and low • Two pills: steps (with a goal bar) and heart rate by default • Three keys: notifications, chance of rain and battery until you set a complication or app shortcut • Bottom pill: sunrise / sunset by default (UV index until set) • Date: weekday, day and month; week number; or moon phase SETTINGS • Colorway: 13 (classic orange, amber, ice blue, green, royal blue, violet, red, pink, warm white, mint, gold, cool gray, cyan) • Filament: Bold / Fine • Glow: Off / Soft halo • Tube mesh: Off / On • Date plate: 3 formats • Motion: On / Still • Always-on: Digits + date & weather / Digits only / Digits + tubes + date • 12- or 24-hour time follows your watch setting BATTERY The face only moves for about a second at each minute change and is completely still in between. The always-on screen is true black and lights under 8% of the pixels: the lit digits inside faint tube outlines, the date and the weather. COMPATIBILITY Works on Wear OS 5+ watches (Pixel Watch, Galaxy Watch …). Built with the Watch Face Format. It is a watch face only, with no phone app. HOW TO CUSTOMIZE Long-press the watch face, then tap Customize (or use your phone's watch app) to pick the colorway, filament, glow, mesh, date plate, motion, always-on style and the six complications. PRIVACY This watch face collects no data. Steps, heart rate and weather come from your watch and stay on it.

Weather and steps readouts now open their apps when tapped, and more data comes pre-filled with the real complications.
