Saturn 3D

Saturn hangs in deep space in true 3D: a banded, slightly flattened globe lit from the upper left, its terminator soft and its lit edge bright, and the great rings in perspective - passing in front of the planet below and hidden behind it above, their shadow laid across the clouds and the planet's shadow falling across the rings. The time glows in big digits in the dark sky above.

Rendered, not painted

Every pixel of the planet and its rings is ray-traced: the faint inner ring, the bright broad ring, the dark division between them and the outer ring with its narrow gap, all translucent and finely grooved, over a field of stars and a soft nebula.

Every hour, the rings sweep

As the hour turns, the ring particles sweep round the planet - the inner ringlets faster than the outer, as in the real rings - while the view tilts a few degrees and back and meteors streak across the sky. Then it settles, exactly as it was.

Tap for the sweep

Tap the watch face to set the rings sweeping at any time.

Three skies

• Blue.
• Gold.
• Violet.

Readings in glass

Steps, unread notifications and battery glow in small glass panes round the planet's foot, the date in another over the time. Put another app's complication there and it shows that app's icon and value.

Easy on the battery

The face is still at rest; the sweep plays only on a tap and on the hour. Always-on shows only the time as dim outlines on black.
