Glow Tube

A display tube glows on your wrist, the kind that lights the front panel of a good amplifier: dark glass, a fine wire mesh behind it, the filaments strung across, and the phosphor shining through.

Everything on this face is the time or a reading. There is no picture and no ornament: the light is the design.

The time, large and clear

• Big seven-segment digits for the hours and minutes, with the seconds beside them.
• The unlit segments stay faintly visible, as they do on a real tube.
• The day and date on a dot-matrix line above the time.
• The clock follows your watch's 12- or 24-hour setting.

A tube that behaves like one

• Every minute the digits' phosphor surges and settles: the refresh of a multiplexed display.
• Every hour the filaments surge and a warm wave crosses the tube.
• Tap the glass and the tube runs its segment test: every segment and every dot lights at once, then falls back to the time.
• In always-on mode the tube goes dark and dim, showing the time, the date, your steps and your battery, to save power.

Your readings, on their own readouts

Steps, unread notifications and battery, each under its lit legend.

Make it yours

• Glow: cyan, ice blue or amber.
• Seconds: on by default; switch them off to save battery.
• Three complications on the readouts: steps, unread notifications and battery by default. Choose other data for any of them in the watch face editor. The display types in digits, so a reading that is a plain number looks best.

To customize, touch and hold the watch face, then tap Customize.
