Tourmaline is pyroelectric — warm the crystal and it develops an electrical charge, which is why rough tourmaline in a jeweller's tray collects dust while the stones beside it stay clean. It was the property that first identified the material in Europe, long before its colours were catalogued.

The white gold case measures 37 mm with a gem-set bezel. The white gold dial is set with baguette-cut pink tourmalines and carries white gold Royal Oak hands. The watch is completed on a white gold bracelet set with baguette-cut pink tourmalines with an AP folding clasp. Pink is the palest colour in the 37 mm set, and pale stones are where any mismatch shows first on a Royal Oak bracelet.
