Should really show how a column wheel works. Only because some manufacturers advertise that they use a column wheel as if it is a surperior mechanism. Also, a clearer verticle clutch demonstration would be great.
Very well explained, I always look at the length of a video before hitting the play button (thinking here’s a certain amount of my life that I’m never getting back), however I can say wholeheartedly that time flew by (pardon the pun) whilst watching that explanation of how the chronograph works. Your knowledge and cool delivery compliment each other. Tip of the cap to you Luca thank you.
Just bought my first chrono, a Heuer Autavia with the Calibre 02! The red column wheel is a lovely thing to behold, but having stumbled here 2 years on, would love to see part 2! ⏱️⏱️⏱️
A column-wheel chronograph is very different in operation. It works much smoother, so when you "actuate" the start/stop button it is a silky smooth press, whereas a vertical clutch feels clunky, and it makes the seconds handle "jump". They both do the same at the end though. I didn't really understand how each worked though, so thanks for that!!!
Interesting and well done. However, I do agree with James Kwon, it would be good to learn about the column wheel mechanism and compare & contrast the two mechanisms. So, maybe make a chono #2 video??
Hello again Luka, from Luca. This might be a little hard to picture but there is a kind of clamp (crab claw looking guy) which is held open by the columns of a second, independent column wheel. At the open end of the claw, between the pinchers, is the split seconds wheel. when you press the split second stop button, the column wheel rotates, causing lil fingers on the clamp to slip into the voids between the columns, this causes those pinchers to close up and grab the outside of the split second wheel so you can take a reading. I hope that makes a little bit of sense lol. This article from Hodinkee does a great job of explaining it www.hodinkee.com/articles/a-detailed-survey-of-the-split-seconds-chronograph-and-its-cousins
1:10 Chronograph (mostly) draw power from same reserve, but this fact often leads to a popular misconception : using chronograph will “consume” the power reserve faster. (WRONG!) The correct answer is that chronograph increases friction so that the entire system is more likely to stop earlier when reserve comes closer to the end. Yes it will stop sooner if turned on, but NO it does not consume faster. Rather, the increased friction load will prevent the power reserve to be fully consumed. There are some rare exceptions in which chronograph function does consume more power reserve, but in these cases the watch has to have a separate escapement system that works for the chronograph only.
Hey Luca, you’re kinda a cool guy and that was a very cool video. I’m learning tons of cool ish from these videos from all the way in the rainy UK. REQUEST FOR VIDEO - and this one is (as you Americans say - a doozie!) but can you explain the Equation Of Time complication? Seen on Panerai Luminor’s and others? That’s a real complex complication, let’s see what you’ve got!
I’ve been fascinated by how a minute repeater works. I mean how does the watch “know” what time it is exactly when you pull the lever, and then plays it back with sounds?
@@heyimluca1275 I think it will be a great idea for you to do a video showing you magnetizing a watch. Show it on a timegrapher. Then explain what is happening mechanically that cause it to behave erratically.

Its looking like this vid will have a part two sooner or later, stay tuned!
It'd be interested to see how the flyback chrono works as well
Great video, Luca! Please keep up the video series and your casual style of explaining.
Thank you Chris! There's lots more to come so stay tuned!

The mudflap lady, now I can't unsee it LMAO.
same 😂
Its a blessing and a curse
We need a part 2, horizontal vs vertical clutch. Great video!
Thank you! I will get working on that part two for ya asap :)
I second this!!

Great explanation and visuals! Thanks for taking the time to show the movement. +1000 to get a video showing the movement of a vertical clutch.
My relatively "low horology" Seiko 6138 has a column wheel! Great video, love the casual style!
Why thank you Sean!
Thanks Luca
Thank you Zack!
Brilliant. Love seeing these. Good job Luca
Thank you Bowl of Salmon! Great name btw
Very well done Luca, Great style and content. You got the gift go for it.
Hey thank you Jack, I really appreciate it!
Thank you
Fantastic explanation
Thank you Uga, Go Dawgs!
Thank you Luca!
I just wonder what happens if I try to set to zero while the cronograph is still running?

How does the single crown pusher work on a chronograph monopusher? Please open one and explain.
Thanks again Luca. From Luka ;)
How about a split chrono? What do you add to catch those additional measurements?

I like this guy. The Luca Brasi of horology.
Thanks Nefarion, though I certainly hope I don't end up "sleeping with the fishes" like my namesake
I guess that an overhaul of a chronograph is a pretty complicated thing!
It is indeed!
What was the "Wig-Wag" again...??
I'll show ya eventually, just building suspense ;)
That was really hard to watch! The longest handstand I have ever done and all the blood was rushing to my head 😉
Haha 100 points for following directions!
Nice
Nice back at ya
Is column wheel definitely come with vertical clutch?
Nope. As an example, the predecessor to the movement in this video (Caliber 321) uses a column wheel and lateral clutch
@@nolanreed7090 thanks buddy

Why thank you Scott! Oh boy that is indeed a doozy but I think that would make a great topic, I'll get crackin on it!

Stay tuned, a minute repeater video will be coming!
How about explaining how power reserves have gone from 40 hours up to 70-80 hours… I hear about double barrels, but don’t really know what that means.
So the barrel is the housing/wheel the mainspring lives in, two barrels= two mainsprings= double the reserve of one!
Hey Luca, how does magnetism affect a watch?
Poorly to say the least, magnetism can wreak havoc on the escapement causing the watch to behave erratically or downright stop in extreme cases
@@heyimluca1275 I think it will be a great idea for you to do a video showing you magnetizing a watch. Show it on a timegrapher. Then explain what is happening mechanically that cause it to behave erratically.
Great suggestion! That is actually something you'll see on an upcoming video shortly lol
Damn I forgot! Am I Luka or are you?
We are all Luka on the inside
Came here hoping for the "Homer Simpson Spring", a bit disappointed...but much happier knowing that there is a "Trucker Mud Flap Lady Leg".
Stay tuned, I will answer all your burning Homer Simpson spring questions soon!
When they advertise 50m WR, they are commiting a fraud/scam.
Well im not sure who they is but almost all pilot's watches are tested/rated to 50m WR?
Minute repeaters
You still haven't shown us what a wigwag is.
I like to build the suspense ;)
This really wasn't a great video. Especially compared to some others from the series.
