Personally, I was happy that my Panerai was a Unitas 6497.
It was the main reason I purchased my 177 in 2008. It had the same robust construction as my Colibri pocket watch from 1979.
The Patek 5070 series was strong because of its core movement.
Richemont or Swatch should leverage their movements across brands.
