Porcelain Moon Jar

A white porcelain moon jar - the round, quietly uneven jar of the Korean potters - stands on a sheet of handmade mulberry paper, and it is the dial. Its full body sits round the centre of the screen, its neck reaching towards 12 and its foot towards 6. The hours are written in ink on the paper round it: 12, 3, 6 and 9 in a fine serif with brush dashes between, all twelve numerals, or brush dashes alone.

Brush-stroke hands

The hour and minute hands are black ink, tapered like a calligraphy brush with a slight swell and a dry-brush edge. A slim seal-red seconds hand with a small red counterweight.

Tap for moonlight

Tap the watch face and a cool silver-blue moonlight sweeps slowly across the glaze, with a soft glow round the jar.

Every hour, the light turns

As the hour turns, a warm light travels once round the jar's rim, like the sun passing, and its shading turns softly with it.

The date in a seal

The day's number sits in a small square cinnabar seal, pressed on the paper like an artist's stamp.

Hour marks

• 12, 3, 6 and 9 with dashes between.
• All twelve numerals.
• Brush dashes alone, for the quietest dial.

Three papers

• Ivory mulberry paper.
• Charcoal ink-wash paper, the jar glowing on it.
• Indigo night.

Readings on the paper

Steps, unread notifications and battery, written small in fine ink on the paper round the jar, in the paper's own ink colour. 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 hands move once a second; the moonlight plays only on a tap and the turning light only on the hour. Always-on shows the jar as a faint outline, the hour marks dim and the hands as dim outlines.
