Patek Philippe Oscillomax Escapement Model

- A clip of the oversize metal and acrylic model of Patek Philippe's Oscillomax escapement. Video was shot at the Centre Suisse d'Electronique et de Microtechnique (CSEM) in Neuchâtel, Switzerland.
This watch escapement represents a ground-up revision of the lever escapement, with every flat component (ie excluding the arbors) is grown using 'Deep Reactive Ion Etching' (DRIE), a process that was pioneered in the semiconductor industry.
The oscillating balance (dubbed GyromaxSi) is the latest component to receive the attention of the DRIE scientists, looking more like a 17th century 'foliot' than a classical balance wheel. Even the peripheral gold mass segments are electrolytically deposited!
The escape wheel now also has a revised shape, reminiscent of an anemone, with its weird tentacle-like teeth. The new shape helps provide better shock-resistant banking for the lever and pallets in the event of a jolt.
The oversized demonstration model escapement refused to behave properly initially, due to it being so large, but later the Patek Philippe watchmaker sorted it out, saying, with a twinkle in his eye, that he had "lubricated it with a bit of earwax!"

Boom Boom Boom, I want that in my room !
So do I!!
Very clear and accurate demonstration. Awesome
Wowwww its breath taking
Alagathevictor, this is a massively oversized model of a watch escapement, not of an automatic winding device. I suppose you could say that there are similar features between the two in some respects: in an automatic rotor, a weight swings off a central pivot, swaying back and forth, but it's motions are random. In a clock like you referred to, the pendulum sways very precisely, as determined by its length and by the force of gravity, same as a watch escapement (a hairspring replacing gravity).
Very nice model. Would look damn fine hanging in my workshop. Think might have a go at printing one.
I think if a lot of us Patek Philippe fans ask them to give us the 3D slicer file of this demo kit, their marketing department would gladly provide.
Is there a fundamental difference from an ordinary Swiss lever escapement? I don't see one...
First of all the escapement wheel is totally different. Secondly, the pallet fork receives an extra impulse after complete rotation.
they research and develop advanced materials that have the same friction characteristics as lubricated steel but does not require lubrication, "silinvar" : silicon invariable
the rest it's a conventional swiss lever escapement mechanism
What is different wrt to other escapment
Looks like a glorified lever escapement to me. Beat jewel touches lever fork on anti-clockwise rotation at the end of it`s amplitude.. Not even an overcoil. Someone is kidding someone. Patek failed to make the co-axial escapement.
PS. Maybe a little reduced friction as the pallet jewels operate on the escape wheel teeth in the real thing.?
I cannot understand how this escapement offers anything over the concentric full rim balance wheel made from metal with a low expansion and contraction coefficient. The HS also !!. Temperature is almost always the enemy !.
how long can it hold it's momentum?
They’ll never recover from turning George Daniels down 😆
The balance wheel hits the fork when rotating counter clockwise
The roller impulse jewel does, not the balance (which is not a wheel)
How can the balance wheel replenish energy? If not, the magnitude of its movement will continue decline, but my watch can work without stop for several days. I can't figure out the reason.
energy comes via the wheel on the left . No idea how they did it here, probably a small electric motor. The spring, and the rest that we see here is to control the timing by blocking the rotary motion for a while. This isn't a clock, it's a speed controller component for a clock .
Jose Liu Energy comes from the gear on the left. The balance wheel and spring act only as regulating devices. The energy is stored within the power coil which would come from the gear train eventually ending on the gear you see on the left. It doesn't unspin in an instant thanks to the balance and spring which regulates the unspinning. Watches work like fountain pens. It's a controlled leak.
Thank you very much! This is a model of balance hair spring system, an important part of a mechanical watch . The left part is somewhat like an "escapment" which replenish energy to the balance wheel each time it was knocked and released. The period of the balance wheel- hairspring assemly is determined by its structrul parameters, therefore control the energy dissipation rate of the left part, that is how fast the left part. And thus , the enery stored in the mainspring is released at a constant rate.
Thank you. The other components were not shown in the radio.
Look up the Draw.
It only needs to hold it's momentum for half an oscillation.
como lo hizo?
That 'hairspring' needs adjustment 😊
What powers the balance wheel to swing back and forwards?
Still there? want to answer.
@@_Jigen Thank you, but I know how it works.
I wanted to explain him how ^^
The escapement does.
what exactly is the purpose of an escapement that works in such a manner?
The escapement assembly ensures that the clock ticks on in an uniformed manner. Without the assembly, the mainspring would release all the energy as quickly as possible.
The balance wheel goes back and forth allowing the gear on the left to advance one tooth per swing. In a wrist watch or a pocket watch this motion is governed by the coil seen on the right. In a grandfather clock this is governed by a pendulum.
The main spring is another spring coil in the watch which drives everything. In a grandfather clock they are replaced by weights that you wind up.
i know what an escapement is, i meant this one in particular.
This escapement shares the same purpose as all escapement. Obviously this one is there to show people so it is enlarged and probably not regulating a clock.
Not sure what you are asking. If you are asking what is improved by this design then I don't know. Probably more compact or more precise than the traditional design.
Seems a typical eh swiss lever escapement, cant see clearer the exact details of the exit and entrance pallets. Major difference is the balance wheel, isn't a wheel at all, it's a weighted rod that rotates around it's center of mass.
this is probably the most used watch escapement, Some reasons its used for watches are, it provides recoil/draw which is back pressure so tthat the lever won't move if it is shaken etc, and won't jam the watch casuing it to abruptly stop. Also it does a fairly good job of reducing impact on pallets etc. these escapement are typically good for 38 to 44 hours and can hold times of +- 10 seconds or so per year (don't remember exact numbers just ball park average).
Now I understand how an Automatic Watch Works. It's just like the pendulum in a bornholmerur Watch.
Товарищи, это заскок?
the only breakthrough of the modern escapement is the braking system in spring drive movement from Seiko, the rest just the modification of what we have,
Breaking? Spring drive movement? What is that? You are refering to escapement and balance wheel, no?
I'm quite sure the point of the industry is to not follow the breakthroughs in the first place.
see how _Zenith Oscillator_ works
Since a few weeks totally intrigued by watch and clock escapements....
See here my 3D printed mini version: ruclips.net/user/shortslsmrTDvrY_w
It was the 1st I made...
PL.
and guess what this all is for?
1) make production cheaper
2) impress people with 'high-tech'!
just a conventional lever escapement mechanism with an advanced material they call "silinvar" : silicon invariable
It looks like carnot cycle.. but That spring wiil be destroyed someday .
Rebankin lol. Still a beautiful model.
Deliberate rebanking though.
👏🏻👏🏻 👏🏻⌚

Very nice.
