Thank you for this free educational content.
As a beginner I have been watching many videos... This is, by far, the best explanation I have seen on a watch movement. I like the way you used the toys to build a logic and explain how things come together. Thank you for sharing your knowledge. You are an awesome teacher!!
Brilliant!! I'm just beginning my long journey into watchmaking. I've had two long periods in my life learning different crafts, and I find your world so absorbing. Thank you so much for all of your videos, and we can see how much you love your job.
Had I seen this video when I was in high school (Primary School, whatever you call it) I would have known what I wanted to do with my life. And I would've wanted to come and learn or apprentice under you. Fantastic job of explaining in a way that can be conceptualized.
This is really interesting. I have always wondered how the escapement works and this is the best explanation of it that I have yet encountered.
Thnx for your support Kevin.
This is the very best site in the world-just beautiful
Great video, so very interesting. I have my great uncle's Bulova watch. He told me he received it for Christmas 1945. He was a wonderful fellow, born 1894, passed 4 months after his 100 birthday in 1994. I received the watch then. Its been basically my daily for the last 28 years. It's never required a repair, I have it serviced every 5 years. It keeps very good time gaining about 2 minutes a week. Its still in beautiful condition, 14 k gold filled, and still has the original metallic mesh band. BULOVA, can be proud of this 77 year old workhorse !
Without questions the best explanation of how a watch works that I’ve heard yet. So simple and straightforward. Thanks.
You can see the real passion and love the way he is teaching. It's absolutely amazing.
I agree totally. I'm in the process of getting tools together to strip and clean a Waltham pocket watch.
@@trevorjenkins3934May the force be with you!
I commend you for explaining in layman's terms. I never knew until today how a watch makes this movement! And I wasn't born yesterday.
Very well explained. Thanks for sharing .
I've always been interested in watches and their movements.
Instead, I became a tool & die maker.
Now I'm almost 62, I found your channel.
Great explanation, thank you so much.
At first I was not impressed when the toys appeared. But after watching the whole presentation; GREAT JOB! One of the best, if not the best.
Keep doing videos like this. I love how you break everything down to the simplest detail.
Great examples. Thanks!!!
I've ben looking for about 4 days on how a mechanical watch actually works. I have always loved looking at wristwatches but I decided I might try and take a working one apart and put it back together by myself. But Ididn't understand how it actually worked then I found your video and WOW! Now I understand. I'm so happy thank you my friend you are just the best tutor and I mean that from my heart. I'm so grateful to you Klass. 👍👍.
Just wow. Now I get it! Thank you 🙏
So generous David, thank you so much!
Thank you for taking the time to make this video - it helped me understand some of the basics about springs and watch movements. I feel smarter now!
A lovely presentation: history, science, culture, art -all in one. What a wonderful job you have done with this, Sir. I learned so much and enjoyed greatly.
Wonderful video and explanation. It’s especially good for those of us who novices but fanatics. Thanks!
Awesome video. Excellent explanation of how a movement works. It is incredible that the basic design has not changed in 200 years. As a kid I took everything apart to see how it worked. My brain is not happy until I understand the mechanics. You helped me here. Thank you so much.
Thank you so much for your support Eric!
Superb content sir
This makes me want to open up my mechanical watch and see for myself! Thank you! 🙏😁❤️
That is an interesting rate, 5 Hz . Quartz crystal oscillators are used as they work at 32,768 Hz because it equals exactly 2^15 and a 15 stage binary counter will divide to exactly one second.
The fact that little spring will return almost a million swings is just about unbelievable or that the machine and build quality of these things are so precise and possess such low levels of friction that the momentum is conserved for that long is just mind blowing.
There is a YT channel called MIT OCW (open courseware) and one of the playlists is 3 physics courses, twenty-something lectures each consisting of classic Newtonian, electromagnetism, and wave functions all given by Professor Walter Lewin, a proud and prominent Dutchman. Anyways that's where I learned about conservation principles, oscillating systems, Huygens' contributions (as well as how to correctly pronounce his name!) and so, so much more. His lectures have an emphasis on demonstration and they are absolutely amazing, all kinds of supplemental material, highly recommended.
I found this video because I'm learning electronics and computer processors and ended up a tangent about the clock cycles of a crystal oscillator that it uses 🤣 I love your explanation of stored power and consistent release using the car and teeth. As a child I would always take mechanical toys, watches and cars apart to try to understand how they worked. My grandad gave me his old watches when I was a child in the early 80s and I would open them (and usually break them) simply out of the curiosity of how they worked - but this was a great way for me, as a child of around 8, to learn - and still is!!
Your very funny and entertaining, and you really do Your best to explain in a easy to understand way. Thank you.
Thanks for making the complex seem simple.
The Longitude Problem has made me appreciate more about watches and clockwork!
Thanks so much for your engaging and accessible explanation!
You are great at explaining; Thank you for your valuable lessons!
The explanation of amplitude and how it is adjusted is the first time I've understood it completely. I like the journeyman approach to this. Thanks for the clarity!
I've watched a few videos on how a watch work's & still get lost I'm hopeless 🥺
@@juniorjohnson5961 If interested you will get there. There is a lot of information packed into a small time frame without providing a full physics lecture behind each piece. If you can understand the pendulum period(=time to go through one one complete cycle) is the same unless you change the length of the string or the mass at the end, and does so despite how far of a distance it has to travel in its cycle, then you are doing good.
He then translates the weight on string being acted on by gravity with a weight on wire (=hairspring/balance spring) being acted on by its springy force. Just as a spring attached from above to a solid surface can bounce up/down like is used on car shocks or can be bounced side to side, it could also be rotated around its center. Springs will oscillate with less and less energy per cycle until they reach a state where they aren't moving.
Wasn't brought up in this video, but the mainspring where the wound energy is stored will through gears apply force to spin the escapement (=gear with strange teeth to interact with the pallet fork) and every oscillation of the balance spring will bump the pallet fork allowing a very small rotation of the escapement and the mainspring energy will push the escapement through that available range of motion. The escapement will hit the pallet fork on the other side as it does so and the escapement becomes stuck. The energy transferred into the pallet fork is transferred back into the balance spring. The pallet fork is now stuck waiting until the oscillation of the balance spring pushes into it the other way restarting that cycle.
The watch keeps time as energy goes from a higher wound state to a lower wound state because it doesn't matter how hard the pallet fork hits the balance spring based on energy from the mainspring because the balance spring still takes just as long to run its rotations back and forth (though it will rotate a shorter distance with less energy).
@@mirror1766 Thank you for taking the time to explain this 🙏
You wonderful human. This is the exact video I needed. Instant subscription.
Perfect content!
great job, breaking down the mechanics of a watch, clock, time
Best explanation I’ve seen! Love the enthusiasm for the topic!
I can't believe how much I have learned in just one video - thank you and congratulations on a job well done :)
Very cool, my friend.
Excellent video explained it so well that I now have it straight in my head. Keep them coming. Looking forward to more tutorials and sharing your knowledge.
Thank you.
thank you for this video, after have seen many in 4 days, i finally found yours that is perfectly clear!!
The best explanation I have seen by far 👍
It is mind boggling. Brilliant. Just started watching you and some other watch repair channels. Love it. As a newly Retired mechanical engineer, I think this may be a perfect hobby/career for many years to come. Thank you.
This is great ❤
Very informative. I like how you described how magnetism makes the watch go faster. I didn't know the mechanism for that.
Awesome work thanks for such clear explanation. English is my first language and I don't think I have the vocabulary or understanding you do so much appreciated please keep the videos coming
thank you so so much for this
Thank you for these lessons!
Dank voor je heldere uitleg en al je educatieve filmpjes! Mijn opa was klokkenmaker/horlogemaker/juwelier, helaas heb ik hem nooit in actieve dienst meegemaakt en heb dus weinig meegekregen van de techniek en dergelijke, behalve dat het huis vol hing met klokken. 2x per jaar een hele ochtend bezig met alles opnieuw afstellen hahaha. Alhoewel ik mooie horloges altijd gewaardeerd heb, heb ik sinds enige tijd wat meer interesse in horloges, de mooiste stukken zijn nou eenmaal lastig te bekostigen. Maar zeker nu al die smartwatches zo in zwang zijn is het mooi om kennis te hebben van deze eeuwenoude technieken. Wellicht leer ik zoveel van deze video’s dat ik de Friese stoeltjesklok nog kan maken!
I love the way you teach very simple to understand
Nice to hear, thank you!
Thanks for your explanation. It was precise and enlightening. I learnt so much. I can't wait to see all your videos. I have a few watches at home that have ceased working and now I have some inkling why,thanks to your explanation.
The background music has a purpose: it fills in the gaps of silence: no pregnant pauses.
It makes for a smoother flowing video.
Thx for this video! I‘m not a watchmaker but i try to learn all what i can ! I‘m a collector of vintage Ruhla Watches and this is the way to help me by my self! Thank u so much
So nice to hear, save the Ruhla's! ;o)
@@ChronoglideWatchmaking take a look on my Insta Profile ruhla_fan . There u will find a lot of old ruhla watches
Cool, I Will!
@@ChronoglideWatchmaking if you on insta pls let me know.
@@ChronoglideWatchmaking i found you , you got my follow
Thank you for the explanation. As much as it linear and rotational physics have their relationship, its always taken effort to get them through my head properly. With my understanding of the mechanical motions of a watch, this video's explanation got me to think enough to see how the balance spring regulates time despite the amount of energy put into it from the mainspring's remaining wind.
I just started watching, and great analogy with winding teeth and release of energy in time.
Nice to hear from you!
Dank je wel Kalle - best info on regulating & hairsprings/pendulum.
Fantastisch uitgelegd, helder en rustig, niet te veel info ineens. Prachtig hoe men ooit een oplossing heeft gevonden om het tempo van een mechanisch uurwerk te reguleren! Gr Pim
Dankjewel Pim!
Excellent explanation and visuals.
I absolutely love this channel! Thank you!
Your support means a lot to me, thank you!
Wonderfully clear explanation! Thank you.
amazing thank you so much
Thanks this is fascinating!!
The guy that designed the mechanics of watches is genius.
So many tiny improvements over the centuries, we are standing on shoulders of giants. I fully agree!
That was actually... really interesting.
Fantastic explanation! Thanks for your time!
thank you so much for your support!
This deserves a million watch .. double please make a Video about timekeeping mechanism and escarpment theory please take about the grasshopper escarpment and other versions of escarpment. It seems to me you have a deep understanding of what you are doing.
A million..... that would be very nice, but for now i'm very happy that you are watching, LOL
I'm a teacher in an mechanical engineering university and as a semester project I'll be using a mechanical watch to give some more variation on projects that only focus on automotive parts. This semester I'll ask them to plan an controlling device for one or more components. I thought on using the design of the main plate and get them to control the parelelism and real position of all axles on the gears.
I'm new so I Didn't understood much but it really is mind boggling
Hi I need student in this domain for a concept watch called Romi
I just had this idea of a mechanical watch with a digital heart that can connect to the internet and get atomic time. then adjust the hairspring etc in the mechanical part so it is always perfect.
Great explanation! Thank you!
Applying to Rolex next year. Wish me luck.
I like your toy Porsche!
Well done.
Very educative video. Excellenty presented. Three cheers for you Sir.
Nice to hear!
I'm an amateur astronomer, and of course, familiar with the work of Christian Huygens. Besides his astrronomical achievements, I was not aware that he came up with the ideas that led to the escapement.
The balance wheel is analogous to but different than the physics of a simple pendulum. It is called a torsional pendulum and it's a harmonic oscillator which depends on both the moment of inertia of the balance wheel and the stiffness of the spring. So the moment of inertia is actually a tensor but to simplify it depends on the mass and radius of the wheel.
I'm adding this because I want it to be clear the period has nothing to do with the length of the pendulum in the watch's case. Length is for a simple pendulum, where amplitude and mass don't matter, only length.
Edit: also for simple pendulums, gravity does matter, so pendulum clocks will need adjustments on other planets and won't work in space. But torsional pendulums do not! They will have the same period on other planets and work in space!
Mooie en duidelijke uitleg, bedankt. Eigenlijk nooit zo bij stil gestaan dat een hairspring in feite een pendulum is.
Leuk om van je te horen Joop!
This video rules!
Amazing video quality and explanation!! I still don't understand how this precision manufacturing of these small escapement components were done in the 18th Century ???
The only thing missing is the actual key part: how does the main spring drive the balance spring?
Its almost like how a fountain pen works by controlling the “leak” as it were. Very interesting.
Eine sehr schöner Erklärung der Ankerhemmung und die Unruhe ersetzt das Pendel, sehr gut erklärt. Das ganze bildet dann einen Oszillator des Frequenz man berechnen kann, sehr gut erklärt, danke.
yes!
1 tooth.
Thanks for the video.
Love the video. But it’s difficult to wrap my head around the fact that time between each push of balance wheel is constant. Can someone explain me how the push is always same?
Great explanation. I use a Gauss meter app on my phone and my house is always in the red for some reason, and a demagnetiser always gets the watches running better.
Love the channel!
thank you
Very nice job!
there are a few animations, which show everything in 3-5 min.
Thank you for showing! I am still wondering how the balance wheel is kept moving, or how the escapement gives the balance wheel a push each time and when exactly.
Thanks!
Thank you so much! That is so generous 🙏
Thank you always for the good video、please korean subtitle.
Thank u so much , this is an amazing explanation
Thank you for your kind words and support!
Such a great explanation. Thanks for your dedication and work!
Thanks 👍
👍👍👍
Thanks. I'm getting the idea of how it all works. The Balance Spring controls the rate at which the Main Spring unwinds. I hope I got that right!
You did Joseph!
Great job explaining how a mechanical watch works! Thank you!
I understand now.
So nice to hear from you!
ontzettend leuke uitleg! 😀
Brilliant sir please keep up the good work 👌
Thank you so much! really kind.
