Greubel Forsey Invention Piece 2

About this reference

The Greubel Forsey Invention Piece 2 was introduced in 2011 as a limited edition of 22 pieces, with 11 units cased in platinum and 11 in 5N red gold. This reference is no longer in production. Collectors prioritize this model for its unique movement architecture, which features two Quadruple Tourbillon systems coupled by a spherical differential. The caliber consists of 594 components, including four asynchronous tourbillons designed to average out positional errors. The dial lacks a traditional face, instead utilizing a sub-dial at 5 o'clock for hours and minutes, a small seconds disc at 10 o'clock, and a 56-hour power reserve indicator at 11 o'clock. On the secondary market, these timepieces typically command prices in the mid-to-high six-figure range, often between $450,000 and $650,000. A notable auction result occurred in 2021 when a platinum example sold for approximately $500,000 at Christie’s.
