Glowtube: Digital Watch Face

Glowtube puts the warm glow of a vintage glow-tube clock on your Wear OS smartwatch. Each digit sits in its own detailed glass tube, with the wire numerals, the hex mesh and the dim unlit digits behind the lit one, just like the cold-cathode displays of the 1960s and 70s.

It is a retro, steampunk-flavoured digital watch face for anyone who loves old electronics, valve radios and lab equipment, and it is easy to read: the glowing digits are big and bright against the dark tubes.

• Four detailed glass tubes: wire numerals, hex mesh, dim unlit digits, reflections and bloom
• Blinking neon colon and small seconds tubes
• 6 glow colours: amber, ice blue, green, violet, red, rose
• 4 panel-meter complications: battery, steps, heart rate and world clock by default
• Day and date plate
• Designed low-power always-on display (AOD)

Classic amber looks like a real glow-tube clock; ice blue and violet give it a more sci-fi feel. The panel-meter complications accept data from your watch and compatible apps, so you can show weather, calendar or a second time zone instead of the defaults.
