The “Histoire de Tourbillon” adventure by Harry Winston is coming to an end. This arrangement of watches was the home for the absolute most luxurious pieces made by the brand, together with the Opus arrangement. Having recently utilized tourbillons with single, twofold or triple tomahawks, combined (or not) with single or twofold tourbillons or a merry go round, Harry Winston’s most recent creation is the last page of an amazing book. Be that as it may, similar to every single great story, the end is amazing. Meet the Harry Winston Histoire de Tourbillon 10, the first watch ever furnished with four tourbillons in a solitary movement.
Background: Multiple Regulator Watches
Recently, our specialized supervisor Xavier composed the ideal story to begin this article: “ A Technical Perspective – Understanding the Concept of Multiple-Regulator Watches “. This couldn’t be more precise in this specific situation. In any case, before we move to the purposes for the utilization of numerous controllers, let’s have a fast outline of the industry.
Most watches depend on a solitary controller design. However, for different reasons, a few watchmakers decided that more controllers could provide better chronometric results. For example, a twofold equilibrium or even a twofold tourbillon isn’t actually an astonishment any longer. We’ve seen several watches with such developments – Dufour Duality, Journe Resonance, Armin Strom Resonance , MB&F LM2 , Breguet Chronograph 7077 , Vacheron Twin Beat or Zenith Defy 21 … And many, numerous more.
Then comes the uncommon cases. Having two controllers is as of now a test. Three or four is the exemption. Think about the Antoine Preziuso Tourbillon des Tourbillons , with no less than three tourbillons pivoting on an enormous merry go round. And afterward there’s the Roger Dubuis Excalibur Quatuor, with four calculated adjusts on its dial. Moving to the subject of tourbillons, we think around several twofold and even triple tourbillon watches. However, no watch as far as anyone is concerned was ever fitted with four separate tourbillons in a solitary development. Unquestionably, Greubel Forsey has a watch named the Quadruple Tourbillon , however, we’re talking around two twofold tourbillons (or bi-pivotal tourbillons). This watch highlights “only” two controllers. Accordingly, Harry Winston has come up with something absolutely unprecedented.
Why have more than one equilibrium wheel, when a solitary one would already be able to do the work really well? There are numerous purposes behind this, however, the essential idea is to improve chronometry. It very well may be to manage extra complications – like a chronograph with its own controller, to keep the timekeeping part of the watch liberated from impedances. It can likewise be to compensate for the mistakes of every controller. Also, in this occasion, the more controllers you have, the better the normal outcome you’ll get toward the end. What’s more, here’s the raison d’être of the Harry Winston Histoire de Tourbillon 10.
The Harry Winston Histoire de Tourbillon 10
As we referenced in the presentation, the Harry Winston Histoire de Tourbillon 10 will be the last watch in this arrangement of watches. However, the last section is a genuine watchmaking show-stopper. We won’t begin debating about the design of this watch – clearly, over the top – or even the significance of such a watch – such extraordinary watches are insignificant in any case, and this is the reason they need to exist. So let’s see what makes this Histoire de Tourbillon 10 a particularly exceptional creation.
Certainly, Harry Winston’s most recent creation is a monster of a watch. Don’t hope to fly under the radar when wearing it. The overwhelming rectangular case estimates 53.3mm x 39.1mm x 17.6mm – I’ll even statement the brand here, “the piece is as much a vessel as it is a watch“. It is topped by a gigantic and exceptionally raised sapphire precious stone, a similar material utilized for the actual dial. Time is, however, the lone sign that this watch will give, and it is shown midway, on a raised sub-dial. The remainder of the watch is about technicality.
Three releases of the Harry Winston Histoire de Tourbillon 10 will be accessible. Ten pieces will be made in 18k white gold, ten pieces in 18k rose gold and one of a kind piece in Winstonium, a particular platinum composite. The last can be perceived gratitude to its two enormous blue tourbillon spans. The Winstonium and white gold watches are mounted on crocodile leather lashes with enormous scopes and topstitched with a 950 platinum string. The pink gold rendition dispatches another wristband tone: dark with copper features upgraded by topstitching in rose gold thread.
Let’s proceed onward to the actual development. The four tourbillons of the HW4702 type, which has no under 673 components (with 78 components for every tourbillon), can be found in the four corners of the case. Note that these tourbillon are making an insurgency in 36 seconds, and not one moment as often seen. The idea of utilizing numerous controlling components is to exploit the characteristics of every one and saddle their remarkable method of responding to gravity, the impacts of which the tourbillon is designed to offset. Hence, despite the fact that each will run at its own rate and won’t mark a similar time as the others, a complex arrangement of three differentials will discredit and average their positions, bringing about an apparently extraordinary accuracy of the time demonstrated by the watch. Four tourbillons, three differentials, one bound together sign of the time.
Check the video beneath to perceive how this amazing watch functions in the metal:
The engineering of the development is even. On each side, one twofold spring barrel disseminates its capacity to a couple of tourbillons, each running independently. Associated with these two tourbillons is a first differential, which will average the pace of the left side of the watch. A similar engineering is utilized on the correct side of the watch. A third differential, which is larger than usual and situated in a focal position, does the work of averaging the two past differentials and communicating its data to the compared hands.
However, chronometry is administered by other components than the nature of the controllers. The nature of the force stream that takes care of the managing systems is another significant wellspring of deviation. While four controllers, all associated by differentials, will viably assist with making an absolutely arrived at the midpoint of sign of the time at a moment, chronometric results ought to be steady over the whole length of the force reserve… However, since it depends on a loosening up spring, the framework is imperfect – to put it plainly, the delivery of the force to the controllers isn’t consistent over the term of the force reserve.
To invalidate the majority of the impacts of this decreasing progression of energy, the Harry Winston Histoire de Tourbillon 10 is furnished with two sets of quick winding barrels that are overlaid, mounted progressively, and afterward associated with the tourbillons. Accordingly, the energy isn’t shared across the four corners of the development however conveyed as required. Altogether, you can anticipate this development (if totally directed, obviously) to be one genuine expert of precision.
The four tourbillons, all running at 21,600 vibrations/hour or 3Hz burn-through a ton of energy, henceforth the moderately short force save of 55 hours. As you would expect, the development is incredibly decorated, with modern completions, for example, iced primary plate on the dial side, X-molded scaffolds on the back, straight-brushed and sandblasted surfaces yet additionally the exemplary decorations, for example, anglages or slanted wheel spokes.
The Harry Winston Histoire de Tourbillon 10 is a really noteworthy watch, not just in light of the fact that it’s the lone watch outfitted with four tourbillons, yet additionally in its execution. It is an assertion piece, with no other reason than to be an extraordinary idea – which is reflected in the cost, from CHF 700,000 to CHF 770,000 depending on the adaptation.
