Charles Frodsham Animation Double Impulse Escapement

[@kovko69]

This movement runs at 3 Hz or 6 beats per second (6 ticks), but I suspect something more subtle, clever, and beneficial could be had with this escapement. On the roller pin's return journey, it unlocks one escape wheel (the current impulsing escape wheel) which makes one "tick" sound. The second escape wheel locks into place on each pass, but makes a much smaller tick sound. The detent moves in the other direction to lock both escape wheels, and the roller pin passes by to the other side. However, the second wheel moves before it gets locked. That means that the seconds wheel is moving forward twice per direction of the balance wheel, albeit of different distances. The distance traveled by the impulsing escape wheel is 80% of the distance of a 3Hz Swiss lever escapement, with the other 20% traveled by the following escape wheel. Instead, you could have the beat rate at 2.5 Hz or 18,000 BPH and make the first escape wheel travel 100% of a 2.5Hz Swiss lever escapement, and the following escape wheel travel 20% of that. Then, after 1 second, you'll have 5 regular ticks and 5 small ticks, which is _technically_ 10 beats per second, but the small ticks are only equal to 1 regular tick. That way, it'll be a 2.5 Hz movement at 10 bps instead of 5, while the small ticks add up to make it somewhat of a 3 Hz movement. Alternatively, you could have the second escape wheel travel 100% of the way of a 2.5 Hz Swiss lever escapement. Then, a 2.5 Hz movement will run at 10 bps with each tick equal in interval, thereby effectively producing what a 5 Hz high beat movement does, while running the balance wheel at only 2.5 Hz. It'll still be the same amount of energy release from the mainspring as a 5 Hz movement, but it's doing it with less wear and tear while you can see the hairspring breathe. You won't get the same stability as a standard 5 Hz movement since the balance wheel spins half as fast, but you get a faster sweeping seconds. Despite the slower speed, it could actually be a more accurate movement than a mass production 5 Hz watch, if built to the high degree as you'd expect in high horology. I'm not sure that this is worth it, given the lower power reserve and inherently less shock protection, but it's another way of doing things. With a double barrel and a stellar shock resistant architecture, maybe it'll be worth it.

Would love to see amplitude / beat errors for this movement. Thank you for the video!

[@wayneweir246]

Outstanding video! Great explanation. Thank you.

[@ncooper8438]

Good video, but what's the point of having a double impulse mechanism ?

[@RenoLaringo]

Maybe increase the amplitude and so the precision... 🧐

[@Mephistopholies]

For real! Rock star level. Slaps it on its ass as it goes by...

[@MK-ge2mh]

Does the real watch have an amplitude of 360 degrees as this animation shows?

[@drbobsnightmare2521]

Isn't it like an ignition distributor with dual points. Where the dual points increases the dwell time firing impulses.

Very good machnaziem

Quite amazing

Genius, bravo !

Wow nice beautyfull i, m, fully intrested in clock engine

[@discobbath]

That hurt my brain.

Beauty!

PP escapement

[@ElectricPizu]

Excluding manufacturing costs and difficultly, show me a more elegant and perfect escapement than this!

[@nostalgisong]

Impresionante.

[@ve2zzz]

Arnfield and detent escapements prove that it is not necessary to have double impulse to have high precision.

[@RollaArtis]

All these mechanical watches are old technology. Now, it's not about high precision but how weird enough they are to be successfully marketed.

[@user-rx9ny4yo2e]

@@RollaArtis yeah in general It's Just that. Even tho a Lot of them have actual diference on the watch the majority of times It's too little tô notice or Just a marketing stunt.

[@peruviansalad]

Quintuple “flying” gyro toubillons, don’t engineers usually want to minimize the number of moving parts and surfaces that wear and work towards simplifying, probably why the French lever has stood the test of time although making it coaxial like Daniela did ie current omega stuff makes a lot of sense to me. Also the seiko hi-beat stuff I think they are still using some of those grand seiko is anyways.

[@Tenebur]

simply genius

[@Zzzzalazar]

Why? I have the feeling everyone uses the word Genius very lightly and so often that has lost meaning.

对马国政府来说，第二家园不是什么重要的政策，也不会对马国带来什么大的经济收益。所以归旅游部管，主要的目的就是让外国人来消费才给以长期居住。就因为这样所以不急着落实。
