Thanks for your participation and the information. I know these numbers and don't doubt the 200 degrees, but I have never seen a Rolex document.
Healthy 30xx and 31xx movements can be much better than 200 degrees after 24 hours; see below my example for an excellent 3130 caliber measured 8 (eight) years after a service!
