Description

The Frederique Constant Classic Perpetual Calendar Manufacture FC-776HE3H6 is a rare and highly collectible Swiss timepiece, distinguished by its extraordinary heliotrope stone dial and limited production of just 37 pieces worldwide.
Heliotrope, a mineral seldom used in watchmaking, gives each dial a unique natural pattern with subtle variations of green, black, and red inclusions. This makes every watch truly one of a kind—no two dials are ever identical. The organic texture of the stone contrasts beautifully with the refined case design, offering both artistic character and horological prestige.
Powered by the in-house FC-776 automatic calibre, this model features a full perpetual calendar with moonphase, one of watchmaking’s most sophisticated complications. Originally introduced to make high-end complications more accessible, this collection remains one of the most affordable Swiss-made perpetual calendar watches, now elevated into a rare collector’s piece through this limited “Elements” edition.
