Greubel Forsey presented their latest creation, the Art Piece Edition Historique which pays tribute to this artistic and architectural approach with a creation that sums up and magnifies its true spirit. Following on from previous Art Pieces, the Art Piece Edition Historique houses within its 44 mm-diameter case a new movement with a variation on the theme of the Double Tourbillon 30°: a mechanism designed to enable the balance wheel to oscillate consistently in all planes ensuring maximum precision. The new 475-part hand-wound movement boasts a 72-hour power reserve with optimal chronometric performance, ensured by two series-coupled fast rotating barrels.
It is a veritable sculpture in motion, with its inner tourbillion inclined at a 30° angle performing one rotation per minute and its outer tourbillon completing a revolution in four minutes. The small seconds dials positioned on the same level, between 10 and 11 o’clock. Lifted onto a significantly higher plane,the power-reserve indication bears large Arabic numerals and a blued steel hand.
The case back offers a great view of the Double Tourbillon 30 where all the jewels in gold chatons and polished countersinks are clearly visible. Limited to 33-piece edition, the first 11 Art Piece Edition Historique timepieces are to be made in platinum and the 22 subsequent ones in different materials.
