The escapement is my total favorite part of a watch and I share your fascination with it. This is about the best analysis and explanation of how it works that I have seen. Thanks! (pushing...pushing...pushing...)
I would pay great money for a formal class by this gentleman. Incredible video.
This sums up everything here :'There is no need on that just pride on what you are doing.'
Your passion for these timepieces truly shines through in these two episodes. Quite infectious!
Both parts of your video are brilliant. I loved the way you related the physics of pendulum theory to the watch. Thanks for sharing this information.
Très pédagogique, belle explication, et on sent la passion de l'art et du temps qui se dégage lors de l'exposé. Thanks so much.
I really love your videos. You are actually the first person to mention anything about where the power is generated for the escapement to work. The balance wheel cannot be the source as it isn't connected to the train BUT when others explain the action it's as if the balance wheel has a store of energy all its own that it uses to keep itself moving. Very few people explain that the escapement wheel is the source of this movement (through the main spring) In definitely no expert but I think im right in saying that. As I say - I LOVE your videos. Many thanks
Exactly this. Wholeheartedly agreed!
The escapement & pallet fork is a kind of conundrum, because the impulse pin moves the pallet fork to allow the escape, and also gets a push from it to keep he balance wheel going.
Thank you so much for this Video!
This man should be awarded the Nobel Prize for physics just for his clarity of instruction and explanation of the watch movement. You are my favourite, sir!
Your enthusiasm and presentation is inspiring. As a hobbyist I am learning both the history and science of watchmaking from these videos. Something i have been lacking so far.
Thank you so much Dave, spread the word! LOL

Just found your channel because was looking for error beats [ms] and Hooo your passion and professionalism plus good explanation and humble humour 💯👍 have a automatic 2824-2 it’s been service at the moment the watch maker sent my a photo with 5 amplitudes and in total 0.8 ms this is the media and amplitude media is 224 still needs more service but can you please tell if this is showing average performance for a first service? Do you fix Longines watches I live in Portugal?
I feel like I’m back in school except you’re a much better teacher than anyone I ever had.
Found this channel via YT recommendations. Great presenter; simple and patient explanations.
Beats any of the usual watch channels out there.
Thank you so much, very nice to hear from you. Spread the word! Kalle ;0)
Best explanation Ive seen on YT
Fantastic and seriously underrated.
Great explanation of escapement. Do you plan to continue the video to explain the interaction of the escapement with the power train? So that it ties everything together?
I've loved watches my whole life, but (as you pointed out) I've only recently come to appreciate that the inside of the watch is way more interesting than the outside.
The best in these videos is the way you teach. . . . Amazing Mr. Professour
I'm loving the in depth explanation of movement function. Thank you.
This is very interesting. The skills involved are worthy of envy. Especially the chain made by children 300 years ago that went into a verge escapement.
I will bet there is bout 100 years of history in the construction of the hairspring, and the alloy(s) that it is made from.
I try not to miss one episode thanks for sharing
I wish I had of found these presentations much earlier, there is an art to teaching and this is art at its best, looking forward to future lessons
Im only starting to learn, thank you. Your way of teaching is really useful and Im learning alot from it. Many thanks.
Finally I got how the power is transmitted to the hair spring, tks!
@15:49 "Genius!" LOL Great passion and great video Thanks
Hi Kalle, Thank you so much for explaining the theory of Horology. I am very glad that I found your youtube channel. I am fascinated by mechanical watches and I feel like I want to give up my over 20 years of IT career and start learning about mechanical watch making after watching your videos. Really appreciate it!
Your not alone my friend. I started watching videos of high end watches worth big money then accidentally started a watch disassembly video next thing i know i bought as much specialty tools and machinery as any experienced working professional watch smith might have in his collection maybe even more. Cleaning machine, ultra sonic cleaner, spring winding set, multiple presses, micro screw driver sets, special attachments for bezel removal, tweezers, digital watch analizer, digital microscope, need i go on? I got hooked like you and im in for a penny in for a pound. I needed a hobby at home that combined my experience teaching woodturning and my experience taking apart an old iphone 4 i dropped in a pool and fixed it on my own with help from youtube videos. Who knew it would be horology.
Another excellent explanation with visuals of the physics involved.
Thanks!
Loved these 2 videos on the basics! I know how much work it takes to make and edit. Subscribed!
Thank you so much for your video! You have done an excellent job explaining watch movement that I finally understand. I love your enthusiasm and energy that you exhibit as you teach. Subscribed and following.
A timeless piece of work!
Hi There. Thanks a lot for your explanations, part 1 and part 2. Great job!!
It has changed our society, very true from the railway time to factory time to school time to space time etc. But where now when no body is wearing watches any more but they have telephones with digital time?
Thanks for sharing , when you open an old pocket watch it’s bringing the beautiful European history back to life, how men and women used to dress and everything else around it.
Uw enthousiasme is aanstekelijk, super uitleg!
Excellent. Really valuable education presented in a very clear and interesting way. Many thanks.
I think I watch this video 5 times cant get enough!! I am definitely going to pick up some books on horology! thanks again!
7:43 for my reference
Beautifully done! Thanks!
19:30 I am finding it difficult to watch and disco dance at the same time. haha
Fantastic, I really didn't know all this. Thanks for sharing all this knoledge. I loved.
Thanks for making this series. As a beginner in horology to learn the basics of mech watch operation is quite interesting and amazing. Such skill they must of had to build time pieces back 200 years ago. Truly amazing what humans have created. Im a philosophy major from college so the mathematics they developed and used changed our world. Mathematics is the language used to describe the physical world. Unlike the mechanics of nouns verbs etc we use to describe things that are only found in two places the observable world of color sound thru the 5 sences or emotional states like anger pleasure anxiety which are internal states of consciousness however they are both either in the world as physically observable entities or in the mind as physically felt emotional states. But not math & numbers. They are a language all their own. They neither exist in the world as a physically tangible thing nor do they exist in the mind as a physical emotional state. They exist only as an abstraction and unique language we use to describe our physical world, build pyramids, and create time pieces. This is why math is so important to every field like chemistry physics electronics engineering etc...the philosophy of math is a most fascinating field of study.
OH. MY. GOD.
The concept of impulse was simply ground breaking and mind boggling to me. Reality changed and the fabric of spacetime around my brain curved. THAT WAS SOOOOO COOOOOOL AND I COULD'VE NEVER IMAGINED THAT TO HAPPEN UNTIL NOW. ITS SO GOOD THAT I HAVE PAUSED THE VIDEO AND I AM WRITING THIS COMMENT. OHMYGOD OHMYGOD OHMYGOD.
GOOOODDDAMMMNNIITTT
THIS VIDEO AND EXPLANATION IS SO GOOD.
Hats off to you sir. Thanks a loooooottt. Respect. Keep doing the good work sir.
Regards,
A subscriber whose mind just blew away
Great stuff! Escapements finally explained in a clear way.
So nice to hear Kevin!
Re: 12:30 OH! - the impetus that drives that wheeley thing with the two jewels. Thank you!
Hi Kallie, I'm streaming in from Johannesburg, South Africa. Thank you for an excellent lesson on the movement plus some history as well which I love. Please let us have some more such in depth explanations as we are thirsty for the knowledge. I have inherited a pocket watch in a sterling silver case with a key so, with your help, I now can date it more or less. It is not working and I want to fix it and get it going. Thank you once again.
Thanks 👍
Hi! I loved the lessons! And so nice to see the gravings inside that one where only a watchmaker would access. And now I'm going to contribute back. At the previous video you explained about the length of the pendulum. Let me tell you about the length of a human eardrum. It has a certain length and amplitude of vibration. It also adapts to a certain extent. Now, when you were talking at the previous video, and also at this one, let's say it had an intensity of about 60db as adjusted in my sound system. Then, at the beginning of this video when the music reached about 120db...
By the way, I just subscribed ;-)
Such a great video!!! You have lots of passion!! Do you know if the pallet fork gives impulse to the balance wheel in both directions? Thank you!
Again, it's a winner. Thx for sharing.
Thank you for another great video
excellent video series, thank you! I‘d prefer your wonderful explanation not being interrupted by the music though.
Greatly explained! subscribed! dhanyawaad!
A swiss lever escarpment has 18000 beats per hour.
Does it mean 18000 times tic tac?
With other words 18000 times a full amplitude moving in one direction and later in the other direction and starting a new cycle?
A beat is a tic tac not only a tic or tac?
Love those old pocketwatches. Fusee is beauties!
Aren't they? I fully agree ;o)
Have a tuningfork project comming up.
Ty for your video. 👍👌
May the force be with you LOL
Great videos!!
Cheers!
Geweldige presentatie!
Love It ❤️
Excellent entertainment thank you keep it up
Thnx Afrim!
Wow! I just come actoss this channel and I love it! Thank you Sir!
I have one question, how is power released from the mainspring? Could you make a video on that if you haven't already! Thank youuu!
See part 1
Nice lecture
Thnx Christobal!
Can the impulss D stone fall out of the pallet fork safety mechanism and make the watch stop? If so, what can be the cause and is that a big issue for repairing?
I love your contributions! !
Hi Roman, it is possible for the Shellack to dissolve (alcohol) or get brittle. it is not very common, but it can happen.
Wow! Lever Pallet technology is truly amazing and an inspired piece of technology (genius indeed). Thanks so much for explaining this in so much detail. Other than newer materials I wonder if in your opinion there has been (Invented) an even more efficient way of doing this work mechanically (not electronically)?
The Seiko Springdrive video is coming shortly, breathtaking technology Matt!
😍😍😍
Would the spring drive then be the first real change in 200 years?
I truly think it is one of the more significant in horology. Game changer indeed.
Great video! I'm fascinated by the quartz piece, what's the model?
It's the Bulova Accutron, the one he was showcasing is made in the '60s, and they had a re-issue recently with a more 21st century design (i prefer the old design tho :P)
So let me see if I understand correctly :
- First you manually wind the spring, storing energy.
- This spring is somehow connected to the bottom wheel of his big board, constantly applying a rotating force.
- Then the "pendulum wheel" release the bottom wheel in a timed fashion with the mechanism.
Now here's my question : I understand how the bottom wheel transmits energy back into the "pendulum wheel" with the beseled jewels each steps, but how does it gets its energy at the start ? If each cycle for the pendulum wheel is "spend energy, recieve energy", it needs to have some energy already at the start ?
Great question! It is all in the Impulse, the pallet fork gives the balance wheel a small push. If you like I can show you during a live stream on Tuesday.
10:45
Explain me how the escape wheel is starting moving the fork by pushing the pallete jewel ?
Catch the escape wheel from your model (not the fork) and please try to simulate the real force of the werk engine which is the spring barrel by spinning it clockwise to start the clock ticking.
It`s not possible right ?
How does the real watch doing this ?
I'm not 100% sure what you mean.
His model can't run because there is no balance wheel, the pendulum that swings back and forth hitting the palette fork. He has to use that dial to act as the balance wheel. But the escape wheel does have a force behind it so the palette fork can work.
Why is it unfortunate, children love to build things, I wonder how many grew up to be incredible craftsmen.
Great intentions, but a little long winded and repetitive. The real value-added is the model of an escapement and pallet fork, which explains everything in five minutes. Would have like to know more about how a balance wheel and hairspring are suspended.
I can understand that is is a bit repetitive, some far eastern viewers asked for that. I hope we have found a nice balance in the later video's. Thnx Gerald!
NotGood.
Mechanical watches are GARBAGE obsolete junk for people who drink "Real ale"
I have one in my vast watch collection and it is one too many.
It is NOT the 17th Century anymore ... It is the Year 2023 and we have these things called batteries and printed circuit boards (PCB) using these you can make a FAR superior watch.
