Brass Orrery

An antique brass orrery seen from above is the dial: its engraved plate with orbits, stars and comets, a brass sun at the centre, and its arms telling the time. The long arm carries the Earth round the minutes, with a small Moon going round it every minute; the short arm carries Jupiter round the hours. Twelve engraved stars mark the hours, with 12, 3, 6 and 9 cut into the brass.

A comet on the hour

Every hour, and whenever you tap the watch face, a comet arcs across the plate and a gleam of light sweeps round its engraved orbits.

Engraved by hand

The date and your readings are engraved on the plate between the orbits, in lettering cut for this face.

Three metals

• Brass.
• Silver.
• Dark bronze.

The planets keep their colours on every metal.

Readings on the plate

Steps, unread notifications and battery. Put another app's complication there and it shows that app's icon, or its title where it sends no icon.

Easy on the battery

The arms and the Moon move once a second; the comet plays only on a tap and on the hour. Always-on shows the arms as fine lines with the planets as small rings, the hour marks and the date, dim on black.
