Ruby Heart

A faceted heart-cut gem floats over a dial of white mother-of-pearl, its red light falling softly on the nacre around it. The gem is not a picture: it is ray-traced from a real heart-shaped brilliant cut - table, crown and pavilion facets - so light bends through it, reflects inside it and flashes white from its facets, with a touch of rainbow fire.

A gem that turns

• Tap the watch face and the heart makes one full, smooth turn on its own axis, showing its depth and its facets, its red glints sweeping across the pearl.
• Every hour it turns once by itself.
• Nothing moves in between, to spare your battery.

Ruby, pink sapphire or diamond

Choose the stone: a deep red ruby, a soft pink sapphire, or a clear white diamond with rainbow fire. Each is traced on its own, with its own light on the pearl.

Diamonds for the hours

Twelve small brilliant diamonds in thin rose-gold settings mark the hours, a little larger at 12, 3, 6 and 9. Prefer numbers? Choose Roman or Arabic numerals engraved in rose gold.

Rose-gold hands

Solid polished rose-gold hands with a bright bevelled ridge and a small open heart near each tip, with a dark edge so they read at a glance on the pale pearl and over the gem. A slim rose-gold seconds hand carries a tiny red heart for its counterweight.

Engraved into the pearl

Your steps, unread notifications and battery are engraved into the nacre in three small oval cartouches with a rose-gold guilloché border, each with its small engraved icon. Put another app's complication in any of them and it shows that app's value and icon; set one to Empty and its cartouche disappears.

Always-on

In always-on mode the face turns dark: the heart as a dim red outline, the hour marks and the hands, dim on black.
