This is not new to watchmaking in the slightest. Highly complicated watches have been made for over 200 years.

Henry Graves Supercomplication was made by Patel Philippe in 1933, which was 92 years ago; https://en.m.wikipedia.org/wiki/Patek_Philippe_Henry_Graves_...

An even older example is the Marie Antoinette watch by Abraham Breguet, which was started in 1783, 243 years ago: https://en.m.wikipedia.org/wiki/Marie_Antoinette_(watch)
