Gears and Crankshaft Movement MASTER CLASS

Stumbled across that somewhere too, did not really look at it properly, it did not appeal to me…

Thought I’d share before publishing, so you can have a sneak peek…
Another Genava Gear setup, but this time with 4 of them running in pairs…:

It is worth opening in new window as the small preview does not show its smooth hypnotizing movement fluently.
Yet I would not put it on my old watch unless I wanted it to melt down :slight_smile:

So nice Tom . I would like to see the Seconds Hand rotate with the same move as the Genevas . I wonder how it would look with just one pin on the escapemenr wheel.

I have been experimenting with the formula, so I think I know how to do the timing… I’ll have a go at different speeds and single pin.

I did not check the timing but if you made the 4 Geneve cycle 5 second it would preview perfectly on most of the apps and pages. That would give you a 1.25 seconds tick. What Fun. The Swiss hope to give us 100000. Second in the day. Why not 17280. :joy:

Added single pin.
Upon wake either 1 pin or 2 pin setup is active.

Ha Ha . Are you allowed to do that ???
Yes . I much prefer that . Sadly you would have have to adjust your drawing of the escapement wheel . Are you still PRO or did you start on a Template ? You will have to call it Geneva IV

So I did call it Geneva IV, which in turn made me think about versions II and III.

So here’s Geneva II with 6 slots. I took @petruuccios’ formula and tweak it to reflect 6 slots. I looked into the math, but did not find the formula and had to reverse engineer it to get the values right…

It seems you invented your own formula, that makes the two wheels pretend to follow the pin movement, but actually they are just partially spinning in right time. Still well done, on tiny display its probably not noticable :slight_smile:

EDIT: sorry, maybe I was too quick to judge.
the right wheel needs to be placed in x=238 instead 242 and it is perfect.

It’s a brilliant watchface - it looks real!

Thought I’d share some stats again. 1.5 years later, now with 32 (live) gear watch faces, I have 605 syncs.
Not too great, but OK for me I guess…

KISS Faces do not get lots of Syncs .

This one has it all

So, the original of this was before this post and I wish I had seen it then but most of the people involved helped with the brain ache and @russellcresser helped with the images of the gubbins but another example, I am sure can be improved on by you guys is my early tourbillon:

Another version of up & down movement.
This one is rather straight forward. It was just a matter of timing and positioning.

I came across an interesting looking watch I wanted to recreate just because it has an oddball face with 2 very simple oddball gears. One gear is static and the other rotates around the first in an orbit, driven by the minutes hand, but they’re just cosmetic and not functional to the movement. Anyhow, in the process I came across 2 sources of gear generators that might be useful to others:

These are indeed excellent. I found them both years ago, after the gubbins but never found an inspiration for using them yet. I had forgotten all about them but now bookmarked. Thanks.
