Harry Winston Histoire de Tourbillon 5

Histoire de Tourbillon 5 is the first in the series to be crafted in rose gold. This variation continues in the open-worked movement, which is black instead of the conventional grey.

Building on the technical challenges introduced throughout the series – from Histoire de Tourbillon 1, which explores the movement and sculpture of the complication, to Histoire de Tourbillon 4, which seeks the next level of precision and performance with a tri-axial tourbillon – Harry Winston has decided to, for the first time, fully reveal the exceptional mechanism behind the tourbillon.

Harry Winston Opus XIII (with Video)

Harry Winston Opus XIII Ludovic Ballouard

As you do every year, you were waiting for this one, and here it is:  Harry Winston Opus XIII.  And yes, it is as crazy as it looks.  The Opus XIII has only one thing in common with any other watch and that is its balance and escapement; the rest of the mechanism is the brainchild of independent watchmaker Ludovic Ballouard.  Honestly it is next to impossible to understand this watch just by looking at it — be sure to watch the video below to help you out.

Opus XIII once again defies the conventional rules of watchmaking. Fifty-nine pivoting minutes hands, eleven rotating triangles for the hours, and a sliding trapdoor perform a magic show where minutes and hours appear or vanish instantly — and, of course, tell the time.  Harry Winston believes nothing in watchmaking is beyond human ingenuity, and Opus XIII invariably proves it right.

Limited Edition 130 Pieces

44.25mm x 13.6mm white gold case.

Instantaneous hours and minutes; Cumulative display of minutes via a peripheral, jumping retrograde system with fifty-nine hands; Successive display of hours via a peripheral, jumping system with eleven hands; Sliding shutter revealing the “HW” logo every twelve hours

Minutes accumulate around a track, each five minutes in red, withdrawing in unison when they complete the circle of the hour. Silver triangles spring in turn from a faceted dome to show the hours, rotating back when their duty’s done. Every twelve hours, Harry Winston’s logo is revealed on the dial, only to vanish sixty minutes later.

The fifty-nine minutes hands pivot on a ring of as many steel shafts, each held between two ruby bearings, bringing the number of jewels in the timepiece to 242. No other timepiece ever made has as many functional jewels. The ruby ball bearings for the sliding shutter are so tiny that the package had to be opened in a non-static environment lest they fly off.

Beneath a smoked sapphire crystal you catch a glimpse of what looks like the fan of a jet engine. This is an extraordinary component, comprising fifty-nine jumper springs — one for each minutes hand — carved from a single piece of steel using LIGA technology (lithography, electroplating and molding).

How It Works

The display is produced by two separate power sources working as a team. One mainspring barrel drives the escapement through the going train and keeps the balance swinging at a steady 21’600 vibrations an hour. The other barrel provides the energy for the display of minutes, triggered every 60 seconds by the center wheel of the going train.

The key element is an outer minutes ring driven by the second barrel. Every minute, it jumps forward a step, released then locked by a rocking lever with two pallet stones, controlled by a cam working off the center wheel. A peg on the advancing ring flips each minutes hand forty degrees in turn, revealing them in succession around the dial. At the end of the 59th minute, a second outer ring comes into play, its crenelated rim simultaneously rotating the fifty-nine minutes hands back into their hiding places.

The mechanism for the hours is no less ingenious. Here again it relies on an outer ring that jumps forward every sixty minutes, turning the triangle of the old hour 180° so that it disappears beneath the faceted dome on the dial, and simultaneously turning up the next hour. At the heart of this mechanism is a snail cam that rotates once an hour. A lever drops off the edge of the cam, pulling a rack to turn a pinion that advances the hours ring. At the 12th hour, instead of turning up a triangular hour hand, the hours ring rotates a wheel attached to a connecting rod that pulls open a sliding shutter to reveal the Harry Winston logo in the center of the faceted dome.

Both mainspring barrels are wound by turning the crown back and forth. A rocking pinion engages the barrel for the going train when the crown is turned in one direction and shifts over to engage the other barrel when the crown is turned in the opposite direction. Similarly, when setting the time, the crown is pulled out and turned one way to advance the minutes and the other to advance the hours.

All of this packaged in a modest 44.25mm x 13.6mm white gold case, Harry Winston style.
