G. Daniels Coaxial Escapement - How it Works / Fonctionnement de l'échappement coaxial de G. Daniels

This video describes the working principle of the G. Daniels coaxial escapement.
The coaxial escapement was invented by English watchmaker George Daniels in 1974 and patented it in 1980. By utilizing radial friction instead of sliding friction at the impulse surfaces the coaxial escapement significantly reduces friction, theoretically resulting in longer service intervals and greater accuracy over time.

This is the most wonderful explanation of the co-axcial that i’ve seen. Now i will respect my seamaster 300 just a little bit more. Thank you.

[@Mark-lj1dj]

Best demonstration video of this i have seen

[@Waterpearl_escapement]

thanks

[@738polarbear]

The man Daniels was a GENIUS.

[@Waterpearl_escapement]

effectively

Thank you for this beautiful model, which helped me understand the coaxial escapement. Nice music, too :)

[@frank-espindola]

Excelente!

[@__--JY-Moe--__]

ah! great!! U can hear the sound of the escapement!! congrats!!

[@jimmyd9424]

awesome!
An interesting design!

[@Waterpearl_escapement]

Thank you. Happy you enjoy the video

Great, thanks for sharing

EXCELLENT. This is the best example of showing how the coaxial escapement works. I never fully understood how the impulse was transmitted to the balance until now. The 'centre jewel' of the pallet fork (probably not the correct term) gets the kick from the smaller of the two escape wheels sharing the same axle. Question now is - why does anyone make an escapement any other way now? Why does the traditional lever escapement even exist any more?

[@Waterpearl_escapement]

I think the success of the lever escapement comes from the fact that it offers the best compromise between performance, size and manufacturing

[@patrickfarnburn5704]

Very special but in reality the speed must be more than 10 times faster.
Did you made this by yourself? That's a huge achievement.
Thank you for showing this.
And it is what Jeroen de Jong also said, I now understand better how my Omega watch with calibre 2500 works.

[@Waterpearl_escapement]

that's right, the angular speed of the oscillator of the watch is more than 10 times greater than that of the model

[@CyclingNeko]

Without the slow motion, I would still confused why this model only has one way to power the balance wheel.
It turns out, that the second one is at a different location,

[@danarmelle56]

joli, joli

[@user-pj8uj7wx3s]

This escapement looks good but it needs an extra wheel and pinion which no one mentions.

[@Legrandmiam]

Q: Where does the force pushing the orange wheel to rotate come from? Sorry, new to watches... Thank you!

[@Waterpearl_escapement]

The force comes from the barrel containing the main spring, via the gear train

[@maxdn8568]

Hello, would you share your drawings? I'd like to make it too

[@vincomens]

Great model. What is the purpose of the ruby laying flat under the pallet? It doesn’t look like it serves a purpose.

[@Waterpearl_escapement]

these rubies are part of the palette

[@vincomens]

@@Waterpearl_escapement I looked it up on Google, it seems to be called a guard pin. Supposedly meant for shock protection preventing disengaging. Thank you. I’m working on this model right now. I can DM you a screenshot if you’re curious.

[@mauriciomucino1015]

Please tell me I can buy this as a Kit or ay least instructions and plans for diy

[@Waterpearl_escapement]

I only made one model and I'm sorry I can't sell it. Thank you for your understanding

Perfert explaining of Co-Axial

[@MostlyIC]

I've watched it many many times now and still don't get why the fork has a middle tine, which seems redundant with the upper tine, at 1:24 that middle tine and the grey escapement tooth are labeled "indirect impulse", which is confusing because isn't it the balance wheel that needs the impulse not the fork, then later at 1:54 the upper tine and the orange escapement tooth are labeled "direct impulse" and the balance wheel gets its needed impulse.
for this to make any sense for me the things that need to be explained are
why are the "direct impulse" and the two "locking repos" actions less friction here than in traditional escapement,
and why the second escapement, wheel which seems to only power the fork not the balance wheel,
finally a note to the builder, the acorn nuts on the rim of the balance wheel are very distracting and obscuring, we can see the wheel's rotation just fine from the wheel's spokes and from the hairspring.

[@Waterpearl_escapement]

The middle tine of the fork has the function of preventing overbanking, it exists in most escapement.
For the indirect impulse, the escapement wheel gives the torque to the fork, which retransmits to the balance wheel through the impulse-pin (roller-pin) of the balance wheel
