What is your holy grail watch? Of course, there can only be one—the Greubel Forsey Invention Piece Number 1 in platinum. Eleven were made from 2011 to 2011, and all sold. I own number 00/11—the grail, plus the seal of friendship from the two founders, Robert Greubel and Stephen Forsey.
Why do you like this watch more than any others? This is a museum-level work of zero error, and composed of impossible angles and an incredibly precise assemblage of parts. It has the most impossible level of craftsmanship and mechanical excellence. I love the characteristic blackpolished bridge, which holds the world’s only double tourbillon—a concentric balance wheel within two cages, both oscillating at different speeds of more than three times the rotary count. The Invention Piece 1s made between 2004 and 2007 have round or semi-circular aerofoil-like finishes, which is a near-impossible gargantuan task to make by hand—and currently impossible to achieve by machine. Note that there are no round surfaces on any part of the watch, not a single one. Plus, platinum cannot be polished, cut or burred like other metals can. It sticks, and hardly loses any mass after polishing; it is simply massaged back into the scratches. Its rarity and properties make it extremely costly to shape or work with. The amazing thing about Greubel Forsey is that it makes very little profit from its watches, and you get exactly what you pay for.
Do you have more than one holy grail watch? There’s a phrase that has risen in recent decades—portable wealth. The indestructible, verifiable, value loaded and extremely small wristwatch is inconspicuous, and you could carry $10 million on any wrist, pocket or bag. Among the most genuine, the most stable, the least likely to be replicated sources of portable wealth are only two watches: the Greubel Forsey Invention Piece 1 in platinum, and the Greubel Forsey Platinum Double 30° Tourbillon Vision with a mother-of-pearl dial.
