As someone that is new to timekeeping or watchmaking if you will I cannot begin to express how thorough and historic your content is please don't ever stop you have helped me pick up the most interesting and fun hobby I have ever had thank you again my friend

This is the best video I have watched explaining watch timing. You make it sound so simple and I simply love the way you explain a concept. 🙂. Keep it up!

Fun Fact: Huygens did work in horology (the pendulum) as you pointed out, but also did work in optics, specifically for telescopes. Watchmakers use high magnification loupes (usually 12x and above) that have two plano/convex elements in them. This is essentially Huygens eyepiece which he developed for use on telescopes, but it also got used on microscopes, and eyepieces of the time were also useful as loupes even before there was anyone who would be considered a "watchmaker". We truly do stand on the shoulders of giants.

All poodles are dogs, but not All watchmakers are as fun to watch! 😉👍

Absolutely fantastic video! Not only an excellent explanation, but the context and enthusiasm are just such a pleasant addition, thank you.

Thanks, thanks, THANKS! You gave me so much knowledge, and fun in the same time! As a hobbist watch machinator I learned so much from you. You are so professional, and explaining everything in a good, easy and scientific way in the same time. Thank you.

I;ve seen two of your videos now and these are seriously the best lessons ive seen. Blew my mind when you showed that the balance spring is the same as the pendulum! So interesting

I improvised a tool, because there seems to be no wrench you can use to lay on top for safely adjusting the "balance spring". Instead, one has to really push the timing pin at the edge of the balance spring. That is tricky, and one can easily slide down and destroy the balance spring! I am also spastic after a stroke 5 years ago! (why I have time for DIY watch fiddling) If the phone rings, my whole right body side twitches! So I took a small 1mm wide jeweller's screwdriver. I cut out a square notch on a corner on one side. I can then lay the screwdriver on top of the pin-lever with the cut-out part. It looks like a plate with a square cut out on one corner. Now I can push forward, and the edge of the cut-out pushes the timing-pin lever. I do not have to worry so much about a twitch, because the jeweller tool does not so easily drop down to damage the balance spring! I regulated all 4 of my Seiko/TMI NH35A (close relative of earlier 7S26 and current 4R35) to within -1 to +6 secs/day when I wear them, or they are on my watch-winder carousel. These watches cost between 45 and 70 dollars, so getting this close to "Swiss" COSC performance, for 1/100th of the price, makes me very happy

Brilliant! I`m no horologist but always loved old pocket watches. I have bought a few, cheap models, and one today is running really fast! Like 5 minutes every 2 hours. But after this I`ll have a go at slowing it down. Thanks a lot you really make this stuff easy to grasp!

Excellent explanation. Much appreciated. A pity however of the bad / hollow sound.

Very good , liked the poodle explanation .

harihkasın saat konusunda ve anlatımında muhteşemdi hem anlatım hem sunum hem gülüşün keyifle izledim sıkılmadan dinledim

I skipped school today, but now I've done my homework and caught up! Thanks for another concise and informative session.

A teacher who uses real life exemple to make you understand the whole thing! You can count me as a new subscriber sir!

This is definitely the best video on this subject to be found on KZfaq.

6:00 that explanation was genius.

You are truly the best on KZfaq

Thank you for explaining things so well. Your channel is my first stop when I have questions like what you went through here.

Excellent video! Thanks for the thorough explanation.

Keep it simple! This is how I would tell people even though I'm not a watchmaker (yet). The spring under the balance wheel is called the balance spring... the type of spring used for the balance spring is a hair spring. I'm gonna teach myself how to repair watches and I watch a lot of videos and I'm gonna order a book.... Practical watch repairing by Donald De Carle! And I'm gonna sub to your channel to learn as much as possible!

Thank you for taking the time to fully explain timing in such an easy to understand manner. There are no horology schools in my city so all your videos are really helpful. Thanks again.

This is the best video explaining watch timing movement. Great Job and Thanks.

I adore your videos Kalle. Your teaching methods are so simple to understand and are a joy to watch.

Superb explanations! Many thanks for making watches fun

Excellent video! Thank you very much for explaining both the process and the principals behind the process for adjusting the timing of a mechanical watch.

Kalle, thank you so much for your lessons! The simplicity with which you explain the fundamentals of how watches work is motivating! Greetings from Rio de Janeiro, Brazil!

When you spun around on the bench, it was sort of like MxVxR...your mass did not change, but your radius did, so your velocity had to change...

Yes. You’d explanation is precise and clear. Thanks

Thank you so much for sharing this video. Very well explained. Everything makes sense mechanically.

Thank you for an excellent explanation of timing and adjustment.

Your enthusiasm is infectious, great tutorial....thank you.

Extremely clear explanation. Now I understand it. Thank you!

Marvelous explanation, thanks

You are a great teacher, thanks a lot for making these videos...!

Great video. I like the way you explain things. Thanks.

Thank you! This was very good explanaiton!

Thanks so much l love this work l regard it for me as a hobby every bit of knowledge helps many thank for your time and efforts

Alweer bedankt voor een duidelijke en simpele uitleg.

👏👏👏 Excellent video, very well explained, I get it now, been practising the pendulum timing on my bathroom pull chord and it's all true, to speed up timing reduce the chord length, voila!

Great teaching it’s very enjoyable to watch and learn from your experience.

After this video, Kalle has been added to my list of favorite Dutchmen. That list is only Kalle and Max Verstappen. 😆

Nicely explained!

Excelent vídeo! Many greetings from Perú!!

Great video! Love it and it is so fun. Would hope to listen about the explanation of delta on the machine from you.

Fabulous. More please!

I believe those explanations are very clear and also very creative. I would have added a couple of minutes showing the actual adjustment of a watch, probably you already have already shown it on another video that I have not seen :) Enjoyed your video and learned with those practical examples, great!

Great explanation!!!

Best explanation ever.

Great explanation very balanced 😊

Alles heel duidelijk. Ik gebruikte de watch Accuracy Meter App, maar de rate ging tijdens het meten van plus 20 naar min 80 en variaties hierop, beat error is 0,1. Ik begrijp niet wat loos is met wat ik doe, het uurwerk is een seiko NH35A

youre crazy man ,enjoying the work you do i enjoyed the way you explain😁

Love to watch your vids and appreciate how you always have a smile on your face. I have another video suggestion-I did my first repivot. I center drilled three different pieces and not one turned out concentric. They looked to be dead center at first but didnt finish that way. Any drilling techniques would be appreciated

Nice lesson, thanks for this. I was hoping for a explanation on how to adjust the beat error, but that's probably for another video.

Excellent video and information. I don't understand why you don't have a million views. 👍😎

Thanks!👍

Was a good one, as usual. enjoy the weekend

Thank you

Is me again! Kalle, is a Rolex OYSTER PERPETUAL Air - King PRECISION 1990

Great info….Thank you! 👍🙏🏼

First I want to say I love your videos and as a new watchmaker hobbyist I was wondering if you would consider making a video discussing endshakes sideshakes covering the barrel jewelsettings and balance? What is correct what is incorrect. I have struggled with this for a very long time don't know what correct adjustments should be for a watch to run properly. When the barrel doesn't have enough or too much endshake etc. How to adjust etc.

Geweldig!!!!

Great video! I was wondering, when looking at adjusting in multiple positions, how do you adjust an individual position if one is way off? Not sure if this is possible or if you just just average all the positions when adjusting to 6 positions.

Quite a cool guy.

Yes master im using , a computerize, microscope when calibaating a watch. Specialy the hair spring. It isa very sensitive. And progile... In a compututize micro tuning i can see clearly the moved ment , speed and clearance of the hair spring while in motion..

Thanks!

you are genius

I enjoy watching your videos. I like to work on old pocket watches and clocks. It is just for my own entertainment. The parts that wear the most, those that move the most are often the most difficult to fix or even find replacements. Balance staff pivots I find the worst, often broken or chewed up in fractured jewels. American watch parts more easily identified and found than old European varieties. Are there suppliers or do you end up making the replacements?

Gebruik een microfoon. Op je kraag bijv. Het klinkt nu alsof je het in de doucheruimte hebt opgenomen. Inhoudelijk een goed verhaal. Maar om te beginnen met het verschil tussen hair-spring en balance-spring zal makkelijk mensen afschrikken om zich nog te concentreren. Ik ben docent en weet dat studenten zelden het klaslokaal verlaten als ze het saai vinden. Maar bij een online presentatie staan ze met één muisklik buiten.

I have a question, could a watch be adjusted to take 16 hours per revolution instead of 12? This is a very informative video, thank you!

Bravo

Thanks for nice explanation . I have a french carriage clock. It is gaining about a minute in one hour . The timing pin is not effective. Please suggest the solution. Thanks

I was always curious about why you’d use the term “balance spring”. I thought you didn’t know (or didn’t care) it was called a “hair spring”. Now I know better! 😉 Do you know of any other applications for hair springs? As always, great video! Thanks 🙏

Thanks for an other great video, know i want to be your student aha

Thank you for the video! In what circumstance would you move the stud to adjust the timing?

Hi. Realy learning a lot from all of your videos . I tried to regulate a 2892 a2 movement ,after i serviced it. Before the service, it was slow. Now , it has a different readings depending on a position, and amplitude changes too. The amplitude veries from 250 to 310. The beat error is good. 0 to .3. The rate is from -23 to +20. Up,Down, 6 , 9, 8, 3, 12. , all different. I use a witshi g4 regulator. From my previous expiriences , the irregularety usualy goes away after i service the watch. Could it be that i need to put a new main spring, i used the original, it looked good. The watch is not older then 20 years.I kind of averaged the rate error. Do not know, if this the correct way of doing it. Its is a ramond wyle.?????

I am interested in further explanation of timing in positions. What elements can be adjusted in order to reduce the variation between positions?

Hi! Kalle, can you help me how to regulate the balance spring from a Rolex Air - King automatic 1990

Using a clip from an ice skater that moves their arms in and out also shows the speed concept of weight in and out.

Interesting video! Does anybody know why Rolex uses a different approach with the microstella screws? Is it because they use a bridge that is screwed down on both sides?

So can we use a different balance wheel in a watch,, (with a slight fifferent weight' or size, and then compensate, or it will bring other problems?

Great explainations Kalle! Would love to hear about free-sprung balance sometime too!

Great info Kalle. Why does the stud move when I adjust the timing on my old Heuer?(valjoux 724) It's very annoying. Is there something that can be done to prevent it?

I have a question. The bet error will off course vary depending on position, but I'm wondering if it's always adjusted for dial down position?

can some body explaine me why my watch when on the desk horizontly dial up will run quickly about +170s and beat error 1.7 and when it on the desk horizantly dial down like adjustment position will work perfektly near 0s and beat error near 0.3 !

Interesting! is there a risk when the balance is "hacked" (stopped) to make it move (to get the microstellas?) My co axial (from 2007 not the latest versions) is 5sec fast and I would like someone competent to regulate it....Thanks a lot

My AS 1688 is gaining an hour a day!!! After service. So I have no idea what to do with it now so I’ll move the pin against the stud and see but that didn’t work last time.. ugh!!

My Seagull ST13600 is around +13 seconds/minute or 18,720 seconds/day and it stops regularly. Moving the regulator has no incidence at all on the timing. The spring of the oscillator seems bunched up but I'm no expert.

fascinating‼️®™️☑️☑️

bro how to set time fenlon global watch

My seiko 5 sports i bought two months ago runs 2 minutes faster . What is the permanent solution to adjust it to the correct time.

I love you lol

How do I regulate a tourbillon? It's Chinese so no real risk of losing the cost of a nice car or anything if I slip... But if you push it while turning the tourbillion stops which is scary. But if you stop it you have to wind and unwind the watch between every adjustment... What do I do?

👍👍👍 🇧🇷

On my Cortébert Automatic CAL 451 bumper automatic, the watchmaker had to put the balance wheel hair spring to retard. He says that the force from the new main spring causes the watch to run too fast. I can attest that when a former watchmaker adjusted the watch after decades of sitting on a drawer on my parents home, the balance wheel spring tension lever was in the middle position. However, the cleaned movement run 5 minutes per day faster. I believe that the causes are other. Having the lever all the way in retard, means that the hairspring has been shortened perhaps as it was bent or broken by the curious son that is writing these lines and in order to run normally it had to be shortened! Albeit, the watch runs perfectly with no minutes gained nor lost in continuous usage! Should I source a very expensive CAL 451 over on eBay to have the balance wheel arbor replaced?

Looking forward more videos on balance spring modifications.. Still it is a nightmare to me 😉

Nice. Where the f i should find rolex watch tool to sell? 😂😂😂

Cant wit 26h , it is so interesting

When there are more tools than a watch parts,,, that can be a problem

This is only a theory, show us the real adjustments on balans wheel

i disgusted my coaxial deville because of that its late 2min for a day and i need 150 dolar tool to adjust its robbery
