Hello! I am just now starting to develop a keen interest in mechanical watches. I am a mechanical engineer and have always been highly interested in mechanisms. This is why I am a hobbyist small engine mechanic. I do so very much appreciate the video you posted and the information you provided. I admit that I have to agree with Alex Laing. Your video makes clear to me how the coaxial movement divides and separates the regulation function of the escapement from the power function. A standard escapement requires a "nudge" from the pallet fork to push a small amount of main spring energy into the balance wheel motion. Due to the angular nature of that "nudge" the action of a standard escapement is not very efficient and requires each pallet fork ruby to perform two functions....although each of the two functions acts on different surfaces of each ruby. Same goes for the escapement wheel teeth. The coaxial movement supplies the power to the balance wheel assembly via the second smaller wheel. Very ingenious! Thanks again. Without your posted video I would not have figured this out! Much appreciated! And thanks to you Alex for confirming what I thought I was seeing in the video. You cleared up my confusion!

Thanks PM245, but since I have no background in ME (other than a physics course), I rely heavily on George Daniels' book, 'Watchmaking.' Beginning on page 245 in the chapter on escapements and Appendix III there's a lot of material on co-axial escapements, and while I understand the basics, I think that an ME would find the depth of that discussion far richer than what I could correctly relay. In any event thank you for your kind words and if you see any aspect that would help clarify or correct my comments, I welcome them. Kindest regards, Bill

Hi Bill. I’m sorry to say that in this case I fear your often high-quality information is incorrect! The advantage of the co-axial escapement over the lever escapement has got absolutely nothing to do with the fact that “friction is divided between two wheels” or that there are fewer “hits” per wheel (indeed the notion of “hits” is irrelevant since it is not contact per se that creates friction). Nor is the primary benefit the reduction of the ruckus in the watch. The point is that, unlike the lever escapement where each of the two pallets need to provide both a locking mechanism as well as an impulse to the balance wheel, the co-axial escapement separates these two functions and therefore means the impulse can be radial instead of the sliding action of the lever escapement. Without this sliding force, theoretically the escapement needs no lubrication, a feature of a normal mechanical watch which increases in viscosity over time and in turn reduces accuracy. If you want to learn more about this, I would highly recommend watching Daniels’s 1990 lecture to the American Watchmakers’ Institute. Alex

Alex, thanks for that clarification. I knew that the there was less need for lubrication, but I thought it was because the co-axial caused less friction because there was less contact per axial. I have Daniels' book, Watchmaking, and I'll go over that again and add any clarification to #82. I'll make it right after checking what I said and what Daniels says in his book, and I will indeed view the 1990 lecture. Kindest regards, Bill

Main idea seems to be that the impulse to the oscillating balance wheel is given in middle point of the oscillation, when the kinetic energy is at is largest and no potential energy. Then the impulse has the least effect on the frequency. (adding only very little speed when the speed is highest is effecting less than pushing nearly stopped balance wheel. So the idea is really separating impulse function from the escapement function. Explanation to patent examiners seems correct. ( I am a patent attorney and former examiner.) I was wondering why basic escapement looks to give two impulses in bad times of oscillations. Problem solved here.

I am trying to understand the advantages of the co-axial escapement. If You watch animations of the Swiss lever escapement here on KZread there seems to be no difference in the moment of giving the impulse to the balance wheel (I mean the one with the spring inside). On the other hand there is a relatively long period of time in which the pellets of the anchor slide off the teeth of the anchor wheel after having blocked its way. If You then watch the co-axial escapement You’ll see that this sliding off is completely eliminated and the addition of another starlike wheel allows a pure blocking function. So we come back to the question of friction. In my opinion this is what omega mean by reducing the need of service. Any answer very welcome!

Rojer Smith has done presentations on the Co-Axial escapement many times and he tells the same story each time. The argument for this escapement is lower friction than the standard escapement, so the need for lubrication is substantially lower. It's argued that a movement using this escapement can go much longer without maintenance and still keep consistent time.

Let me make it VERY SIMPLE for everyone... (1) The Co-axial escapement does not use inclined surfaces rubbing against one another to propel the pallet fork and hence balance wheel. (2) It used one set of pallets for locking and another set which is directly pushed when the first set unlocks. (3) This reduces friction and greatly reduces the lubrication needs. That's all! Everything else is simply mechanical convenience and packaging efficiency to effect the above.

Hey algorithm007ify, from what I know of the Seiko Spring Drive, to some extent it's a quartz in sheep's clothing. While the generated electricity is mechanical, the oscillator is quartz. Not a bad thing and certainly ingenious. As for the Zenith movement, the quantum vibrations are the stuff of quantum physics, which post-dated my physics course. So, all I know about those good vibrations are what the Beach Boys tell me... At one time I delved into quantum programming, and it hurt my brain; so while not wholly unfamiliar with what phenomenon Defy Labs harnessed to produce the balance regulation, I'm mired in the fuzzy logic required to really understand it. Kindest regards, Bill

I feel the explanation of this Co-axial escapement in this video is not totally correct. Here is my explanation. Out of the four pallets existing in this escapement, their roles are as follows. Look at the diagram at 18:22 in this video, as the others have a slightly different action. There are two pallets whose role is destined for the locking mechanism of the escapement larger outer wheel and there are two other pallets whose role is destined to impulse the periodic rotation to the oscillating unit. Let us name the pallets as 1, 2, 3, 4 starting from the left to right. 1. The two locking pallets are 2 and 4 both of which engage alternately on the larger escapement wheel always going clockwise. 2. The two impulse pallets are 1 and 3. Impulse Pallet 1, (anticlockwise) on the oscillating/rotating sprung unit, engages with the large escapement wheel (clockwise) and goes with it AFTER pallet 2 unlocks it. The longer Impulse Pallet 3 (anticlockwise) engages with the central wheel (clockwise) and goes with it AFTER pallet 4 unlocks the larger escapement wheel. That is basically it. I do not agree that there is no surface friction on these pallets as there is a slight radial sliding friction on all four of them WHEN THEY ARE IN THE PROCESS OF DISENGAGEMENT. When they engage, there is no sliding friction as they would be in the right position before the respective touch occurs. Note that while the large escapement wheel has an instant impulsive STOP rotary arresting locked action on pallet 2 and 4, the impulse action on both pallet 1 and 3 is a gentle engagement on the move. Hope that helps the newcomers to the Co-axial escapement. Note that if this escapement is made with more teeth on the escapement wheel, it would not work as when impulse pallet 1 is moving anticlockwise it would hit the tips of the large escapement wheel. George Daniels had no choice in this as the angle of engagement of the radius of pallet 1 and the radius of the large engagement wheel is very critical for this co-axial escapement to work. I believe that pallet 1 engaging on the escapement wheel was an untidy afterthought, but still with eight teeth or seven teeth pallet one could engage and flies back without hitting the large escapement wheel. I made a few wooden models of this co-axial escapement, it works, but I do consider pallet 1 as an untidy and unelegant mechanical arrangement which makes the co-axial escapement very UNSYMMETRICAL in its operation. It works, less sliding action, but rather mechanically unsymmetrical and untidy and needs great precision to make it work.

I am impressed with the SWATCH produced movements Tissot has been using in their chronometers in the last few years. With these, Tissot swept the 2015 Chronometer held in Le Locle, Switzerland. The elitists contend SWATCH chronometers are ruining haute horology. I see it as the Swiss finally responding to those of us who want high precision at affordable prices. My Tissot Luxury Powermatic 80 Chronometer was two seconds slow by atomic time for the month of September. This from a watch that retailed for $1075 on a leather strap.

+Robert Williams I didn't know about the Tissot. Thank you for that! I'll have to look into that brand more closely (as into a few others I suppose). Cheers! Addendum: It has been mentioned by some 'experts' in the industry that eventually the Zenith Defy Lab technology will trickle down (be adopted/adapted) by other watch manufacturers and be available in watches below the $5000 range. Wait and see...

What about the grand Seiko spring drive. That seems interesting too

I've been reading a little about it and looks a really interesting technology - I guess there are polar views in that it is not a traditional mechanical watch as electronics are involved, but on the flip, it's a magnetic braking system applied to a mechanical watch. But it's mechanically powered. I've always been a fan of Seiko watches and I'm planning on adding a spring drive to my collection at some stage. I'm just about to go for a Seamaster which is why I watched this video and subscribed. All the best :)

The explanation of only hitting every other teeth is misleading. There only needs to be half the number of teeth. if the other half remained, they'd be there doing nothing, except if you want to switch to the other teeth every time you service your watch. That may actually make sense to practically double the longevity of that part - that is, if you can get the geometry to work. Which leads me to think... what if you have a tri-axial, quad-axial, etc. setup? Then you'd need a third, fourth, etc. fewer teeth. I'm sure that there's diminishing marginal returns with each additional wheel after wheel number X, but that wouldn't stop other watchmakers from creating a tri-axial escapement, right? Or, is that too similar and unoriginal to call it their own invention?

Co-Axial also means you are usually dependent on factory service ... increasing cost of ownership. None of the independent watchmakers in my town will work on a co-axial Omega.

Hey JR, you should never own one, then. That'll teach them to innovate!

This is true and this is why I am selling mine! Omega's complete service has gone up, over the years!

My first "high-end" watch was an Omega SeaMaster 300 Master Co-Axial. I bought it for one of several reasons and one was the co-axial movement. However, last month I took that Omega and a Rolex YachtMaster and traded them for a 2010 black dial steel Daytona. I like the Daytona better. I liked the idea of having a co-axial movement watch, and someday I'll probably get another SeaMaster, but not the 300 it was a bit too big. Is your model Swiss Made?

Hi Ryvr, thanks for sharing that experience with a Seamaster. I'm a big Planet Ocean fan; so that would be on my co-axial short list, but recently I discovered a co-axial DeVille, which is more my style. Aren't all Omegas Swiss made? Kindest regards, Bill

Omega may be all Swiss made, not sure. I think those kind of things are kept very secret which is why I hope the Swiss government institutes laws such as the U.S. federal trade commission who brought Shinola to task about its Made in U.S.A. label, or should I say mislabel.

Recently the Swiss changed the rules about what could be labeled "Swiss Made". They can import only certain parts I think or a certain percent of parts. I know a lot of cases were forged in China, but how that counts, I just don't know.

Right they have, but it's not enough. The Swiss need to embrace complete "Swiss Made-ness." They are in danger of losing what makes Made in Switzerland special, unique, and high quality. People will only go so long with being fooled.

Bottom line, my opinion, no short cuts allowed, if it is labeled Swiss Made it MUST be one hundred percent Swiss Made. It's how it works in the U.S..

I really don't wanna be that guy but its co-axial, not co-axel/axl. Nonetheless very informative video and these animations are very good! Fun fact: George Daniels made the co-axial escapement as an escapement that did not need lubercation, but in practice it always gets lubercated.

Hey Shock Wave, both Omega and Roger Smith watches use the co-axial escapement. I'm not sure if it's a patent issue so much as it is fitting the co-axial escapement into an ongoing pattern. There's a new Chinese escapement by Tan Zhua called the "di-axial" that's interesting: www.gphg.org/horlogerie/en/watches/di-axial-escapement Take care and be safe, Bill 😷

Now that the patent rights are expired, everyone now starting to want and use coaxial.. that’s why I said omega is the best, and I will never buy any watch that has a coaxial movement done by someone is not omega, for the very reverence I have towards George Daniels

Hey SB SB, thanks man! Cheers, Bill!

Good discussion, but I don’t see any real improvement, just a difference. And in practical implementation it hasn’t proved as accurate as the traditional pallet and escapement. Omega co-axial movements are no where near as accurate as Rolex, Blancpain, Glashutte Original, Patek, etc. Have had two Omega METAS and they both exceed the +5 in real use by a second or two a day. Rolex seem to easily beat that in real world use. Additionally, for some reason the Omega co-axial implementation, not sure if this is inherent or just their implementation, are VERY thick, making their co-axial watches much less wearable. And even with a lower beat rate Omega doesn’t match the new Rolex movements in time of operation using a higher beat rate (not sure that is all that important, but run time has now become a big advertising point).

Thank you very much for your video. I watched it twice. I still wish I bought a Rolex rather than 2 Omega's. My Omega's are too thick i guess due to this maybe superior movement. I don't really understand it at all But what I do understand is that i spent $10,000 on 2 watches that do not sit perfectly center on my 7.25 inch wrist and that Omega makes a very ugly clunky stainless steel bracelet on the SMPc300 and an awful butterfly clasp on my Aqua Terra. Also do i really need 1.5 Tesla magnetic protection? I may just sell these hyped up Omega's and go back to Grand Seiko high accuracy quartz or a Hi-Beat movement. I love that you not own an Omega.

Thanks for this, however, it might be a good idea for a script to have been written before the film camera was turned on, and the script should use correct terms, not " meaningless" expressions, such for example, " The main barrel gives a kick to the oscillation wheel " all of which is imprecise English language, which is used to describe a PRECISE engineering energy release. Get the words right, rehearse them, and then turn on the camera please, and one last point, human hands, should be kept out of camera, either to adjust the spectacle position on ones nose, or to describe a mechanical procedure, please use words, NOT hand signals.
