Technical Perspective: A Look Toward The Future With The Ulysse Nardin Anchor Tourbillon (And Why Every Watch Nerd Needs To Know About This Watch)
Ulysse Nardin is a pioneer in the improvement of silicon innovation for watchmaking. In 2000, the brand presented its Dual Direct Escapement including silicon get away from wheels. The Anchor Tourbillon makes silicon in watchmaking a stride further, by building an instrument that would have been for all intents and purposes difficult to fabricate with some other innovation. This is the thing that makes this watch so engaging – it is a huge innovative exercise that required a very long time to create. As opposed to zero in on copying existing parts in a development with silicon, Ulysse Nardin (alongside Sigatec , which they co-own) created something completely new that altogether improves timekeeping.
So what precisely makes the Anchor Tourbillon so charming? The Anchor Tourbillon highlights a bed fork without any turns. Indeed, you read that right – the bed fork is suspended in the middle of the break haggle roller with super slight silicon edges. These sharp edges clasp to and fro, permitting the bed fork to play out its locking, opening and impulsing activities without a rotate. Not having a turn implies less parts, and no requirement for grease. I talked with Stéphane von Gunten, Ulysse Nardin’s Manager of Research and Development, to discover more.
HODINKEE: Where did the plan to suspend the bed fork on cutting edges start from?
Stéphane von Gunten: The direction of the old style anchor through its two turns pivoting into little gems was consistently a fragile theme in the watchmaking history. The turns are not greased up and it can at times prompt material wear over the course of the long stretches of capacity of the watch. There is likewise a little play [gap] between the turns and the opening of the gem which can deliver little incorrectness in the escapement . The first thought of the Ulysse Anchor was to suspend the entire anchor on two meager cutting edges to arrive at an ideal situating framework [zero gap] because of this virtual rotate and to keep away from any danger of material wear [zero friction].
HODINKEE: How slender are the blades?
Stéphane von Gunten: The cutting edges have a thickness of 15 micrometers and are 4 mm long. This perspective proportion is made conceivable just gratitude to the silicon miniature machining innovation of [a measure called DRIE for Deep Reactive Ion Etching]. The edges are completely straight over the length of 4 mm, as the accuracy in the calculation is better than .5 micrometers.
HODINKEE: How are the upper bed fork and lower bed fork attached?
Stéphane von Gunten: The two levels are fixed together by our watchmakers with the utilization of two little bolts that have a measurement of around .4 mm.
HODINKEE: Why did the state of the getaway wheel teeth change from prior versions?
Stéphane von Gunten: The [latest] form of the Ulysse Anchor Escapement is a supposed consistent escapement. This disposition permits the equilibrium wheel to get a similar measure of energy, so a similar sufficiency, all through the release of the origin. It assists with getting consistent recurrence of motions in an autonomous way of the force conveyed from the fountainhead . The energy is given from the sharp edges and the departure wheel is presently utilized as a “recharger” of the cutting edges that comes after every drive to the equilibrium wheel . It was not the situation in the main form of the Ulysse Anchor Escapement. It is for this specialized explanation that the calculation of the wheel has been marginally changed by our engineers.
HODINKEE: What do the indents on the fringe of the bed fork connect do? Are they to change strain on the blades?
Stéphane von Gunten: Exactly. These two switches are utilized to place the edges in compression. With the correct compression the framework becomes bi-stable. By changing from one stable situation to the next, a modest quantity of energy is given to the equilibrium wheel at every alternance [vibration].
HODINKEE: Is there any utilitarian advantage to having various thicknesses of silicon oxide testimony on the bed fork and departure wheel?
Stéphane von Gunten: The utility of the [silicon] dioxide layer is to have a low frictional coefficient between the haggle beds. It additionally prompts no danger of material wear [no abrasion]. A base thickness is needed for the specialized properties of the parts, fundamentally to have a low frictional coefficient. Contingent upon the part and its measurements the feel, shade of the part, can be affected by the thickness of the oxide layer [diffraction of light into the silicon dioxide layer]. Little varieties of tones could likewise happen contingent upon the course of the light to the objects.
With the all-silicon escapement in its one-minute flying tourbillon, you truly have a hypnotizing system. As the tourbillon pivots the silicon mirrors light in a lovely manner, with various tones relying upon the measure of oxide statement for the individual parts. This watch is an activity in both conventional and cutting edge watchmaking, and the outcome is proof that mechanical watches have huge loads of space to proceed to innovate.
