MINUTE REPEATER. RARE HANDCRAFTS.

The beauty of cathedral gongs

This self-winding minute-repeater exudes the refinement of Rare Handcrafts with a flinqué blue Grand Feu enamel dial. The white gold plate is hand-guilloched with a swirling pattern, before being coated with translucent enamel. The two "cathedral" gongs ensure a particularly rich, deep sound.
