It's all about the Maltese cross gear! Since the 48 tooth wheel takes 4 years (48 months) to do one revolution and the Maltese cross has 5 teeth, the Maltese cross can activate the subsequent 20 tooth 400 year gear one click every 20 years. Therefore it can open that deeper position for the shifting lever at 100, 200, and 300 years, but not 400 (because it is cut deeper for 100, 200, and 300 only.)
That's an interesting comment! Can you be more specific? CAD has gone from 2D drafting to 3D design to 4D simulation over the years and I'm very interested in the historical timeline of that evolution as it pertains to watch movement design.

It takes intelligence to make it work. It takes genius to make it work simply.
Exactly!
so nice to see
Thanks ElderPinto! Yeah that was really cool! I was glad to see that too!
Absolutely marvellous to see. Thank you for sharing! 👍
Thanks Vostok! Yes, that was amazing! I'm super glad I videoed it because I had to watch it several times myself to really understand it but now I do!
Whoa - I don't fully get it yet, but it's cool to see it modeled at that size. Thanks Dayton.

Exquisite explanation! Thank you
Yeah, thanks to Roy! In addition to knowing how the most complex watch complications work he also speaks six languages! What an amazing mind, right?!
Apparently the 1985 module was designed without a computer…

@@IMakeWatches If I recall, the OG creator of this module Mr Kurt Klaus mentioned it in several interviews.

1 rotation every 400 years.... i'll take their word for it. 😅
