How a Mechanical Watch Works

Mechanical watches have no battery, microchip, or circuitry. Watch parts are machined to near perfection at microscopic sizes and tolerances and can produce accuracy within two to three seconds per day.

Video corrections: 4:55 You can faintly see the ESCAPE WHEEL has a geared pivot underneath it that connects to the FOURTH WHEEL -- everything is connected all the way back to the MAINSPRING. I had a render error that made the gears not turn at the correct rate together, so they don't * appear * to be connected. But they are in a real watch.

Educational models and visual metaphors (like the water hose example from that vid) are great teaching tools. But I've almost never seen educational videos that rebuild the real thing, outside of limited teaching mockups. We think sound waves are flat, squiggly lines and atoms are floating balls, where in reality they look quite different from the drawings used to teach them. My focus is education, yes, but I assume the viewer is smart and would enjoy seeing the real thing, which is something we rarely get to see.

in case anyone's wondering, this is a Unitas 6497 handwind movement. this movement was originally designed for pocket watches. so it's quite big. it only fits into big watches (at least 43mm in diametre). that also means it's one of the easiest to take apart and study since the components are also proportionally big. and it's also one of the simplist in terms of complications. most watches nowadays have at least a winding rotor (an asymmetrical weighted rotor that winds the watch using the momentum of your wrist movement) and a date function (an additional 24-hour counter with 31 clicks per rotation). not to mention some of the more complex functions like chronograph (stopwatch), minute repeater (chimes the precise time to the minute) and tourbillon (a revolving escapement) etc. some more complicated watches can easily have 3 to 5 times more parts than the watch shown in this video. now imagine doing all those purely mechanically within the space of a wrist watch. then imagine these technologies existing 200 years ago. yes they did.

​@@fallinginthed33p gears aren't what's ground breaking about watches. as you said complex geartrains existed ages ago. anotther example would be the ancient chinese inventing purely mechanical compass ("south-pointing chariot"}. that's a working differencial from 2 millennia ago. what's amazing about mechanical watches is the invention of escapment for precision timekeeping, as well as miniturisation of parts enabled by precision manufacturing.

I've been into watches for some time now and had a pretty good understanding of how everything worked. This animation however brought the entire story to life and I could visualise the flow of forces, the precision and mathematics of gear ratios in my mind whilst you were explaining the mechanism. You slowed the animation down just enough to see each component transferring energy to the next, always changing and converting dynamically. It made perfect sense. It's an entirely logical process and this presentation is the best that I've seen yet that truly helps you understand not only how elegant, but beautiful simple work of daring and genius we all still celebrate even after the general utility is gone. Watches are different because they represent time and the bumps, bruises and scratches on our beloved watches each have a story interwoven between the pinions and pallets. Thank you my friend for explaining it so beautifully. Peace time ⏲️

I don't understand how the spring on the balance wheel is kept in motion. What does the mechanism look like that attaches it to the mainspring? Does that energy transfer to the balance wheel through the minute hand gears, or are there other gears that linked everything together?

[@xswooshx]

Hi. I'm not a watchmaker or anything, but it looks like it might be elastic potential energy. Elastic potential energy is "stored" energy that results from a material being deformed out of its original shape. In this case, the spring metal wants to be straight, but he winding force deforms it into a tighter coil until the escapement releases some of it.

[@animagraffs]

Thx Mark for helping out here ... it also has to do with the power exchange I describe, where escape wheel teeth give the pallet fork a tiny push from the mainspring, which sort of "winds up" the hairspring for another half-swing each time. I've shown every part of this watch movement, there's no other significant hidden parts or otherwise.

As I begun recently to watch quite a lot of videos about restoration of watch, this video helped me a lot to understand how watches work. Many thanks !

Q: How does the escapement keep the steady pace when the main spring torque (I would think) slowly goes down?

[@samiam619]

@@WindingDreams Sounds good to me…

[@pferdschur702]

afaik the main spring is built in a way that the torque is almost constant

[@pferdschur702]

from english Wikipedia>Mainspring>Modern: "the outer end of the spring is coiled in the reverse direction", "The semi-reverse and reverse types provide extra force at the end of the running period, when the spring is almost out of energy, in order to keep the timepiece running at a constant rate to the end." Also, the spring only unwinds a bit. also see History>Constant force from a spring

[@motorolalasershot]

Good question. To my understanding it doesn't. As it unwinds the main spring's transfer of energy is reduced. To achieve what you're saying a constant force mechanism is required.
