On May 30, 2011 at the Christies “Important Watches:  Hong Kong” auction,  a rare Harry Winston Opus 6 manufactured in 2006 will be offered to the highest bidder.  Of the eleven different masterpieces now in Harry Winston’s “Opus” series, the Opus 6 rightly holds its place high in the ranks of watch collectors.  This very special Opus 6, one of just 6 ever made, is estimated to fetch between $300,000 – $500,000.  More on the significance of this very special watch, after the look:

Harry Winston Opus (Greubel Forsey) (2006)

Number 5/6

44mm white gold case, manually wound mechanical tourbillon (2 tourbillon cages, 72 hour power reserve), hours and minutes by co-axial discs at 3 o’clock, and small seconds disc at 11 o’clock

Each year for the last eleven years, a new Harry Winston Opus has been created out of a collaboration with notable horological masters (the jaw-dropping Opus 11 was unveiled just last month!).  The Opus 6 was done in partnership with Stephen Greubel and Robert Forsey, with its extraordinary feature being the Double Tourbillon 30° — a one-minute tourbillon inclined at 30° inside a four-minute tourbillon to offset any positional errors and to ensure superb chronometry.

Savvy watch enthusiasts will recognize the “Double Tourbillon 30°” as one (of many) signature achievements of the French-English watchmaking duo, whose timepieces under their own namesake brand sell for hundreds of thousands of dollars per piece.
