Time Machine

The heart of a time machine: a steel box with a window, and behind the glass three chrome tubes lined with glowing bulbs, meeting in an upright Y with a blaze of white-blue light where they join. Orange and yellow cables run in from the corners. The time is on time-circuit displays: black LED windows with segment digits, every unlit segment faintly there, each window with its own embossed label.

The time on the circuits

HOUR and MIN in big segment digits either side of the lower tube. Between the upper tubes, MONTH in three letters, DAY and YEAR.

It pulses

The bulbs' light runs inward along the three tubes towards the junction, one step a second.

Every hour, it charges

As the hour turns, lightning crackles out across the whole unit and it whites out in a blinding flash, then fades back.

Tap for a surge

Tap the watch face and the pulses race in, the junction flares white, arcs of lightning crackle out of it and the screen flashes.

Three circuits

• Present: green.
• Destination: red.
• Last departed: amber.

Readings on small displays

Steps, unread notifications and battery, in small segment displays along the bottom. Put another app's complication there and it shows that app's icon and its short text.

Easy on the battery

The pulse moves once a second; the surge and the flash play only on a tap and on the hour. Always-on shows only the hour and minute digits, dim in the circuit's colour on black.

Make it yours
