Cursed Puzzle Box

One face of an antique puzzle box is your dial: deep black lacquer inlaid with polished brass filigree, a great round medallion of nested rings and star lattice, a brass boss at its heart and fretwork in the corners. Brass studs mark the hours on the lacquer round the medallion, with 12, 3, 6 and 9 engraved in brass.

Every hour, it opens

As the hour turns, the box stirs: its four panels slide apart along their seams and cold blue-white light bursts out of the cracks and the centre - then the panels close again and the light dies.

Tap to open it

Tap the watch face and the box cracks open for you, any time you dare.

Hands that read on brass and black

Slender black hands with a brass spine and edge, a dark halo round them, so they stand out on the gleaming filigree and on the lacquer alike.

Three boxes

• Brass on black lacquer.
• Silver on black lacquer.
• Brass on blood-red lacquer.

Readings on the box

Steps, unread notifications and battery, with the date, engraved in brass on small lacquer cartouches round the boss. 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 box opens only on a tap and on the hour; the rest of the time nothing moves but the hands. Always-on shows only dim studs and numerals, outlined hands and the date on black.
