A heritage of Supercomplications

Patek Philippe holds a long heritage in creating 'Supercomplications'. In 1927, Henry Graves Jr., the famous American Financier, commissioned Patek Philippe to build the world's most complicated pocket watch. Six years later, the 'Graves Supercomplication', complete with 24 complications, was delivered to him.

To celebrate the 150th anniversary, the Manufacture introduced the iconic Calibre 89. A technical achievement never-seen-before, featuring 33 complications and 1,728 individual parts.

And to mark the new Millennium, the Star Caliber 2000, composed of 1,118 parts and featuring a total of 21 complications, joined the exceptional 'Supercomplications' collection.

Una caja reversible única

While a typical watch case usually consists of no more than 12 parts, the case developed for the Grandmaster Chime has no fewer than 214 components.

The Grandmaster Chime does not have a front and a back face in the ordinary sense. Instead, it has two equivalent sides of equal distinctiveness, whichever way it is worn. When the crown points to the right, the user can read the dial with the time displays. The reverse side shows the full perpetual calendar with a 24-hour dial and the four-digit year display.

The Grandmaster Chime has two dials, both crafted from solid 18K gold plates. When the crown points to the right, the wearer sees the dial that shows the time of day.

When the crown points to the left, a completely different yet equally legible dial displays the perpetual calendar side. Both dials indicate the time and the date.
