Girard Perregaux Constant Escapement 2013-2023.
Ten Constant years.
White Gold 2013:

2015 with a different dial and hands:

And the Neo Constant Escapement from 2023, with a different dial, hands, bezel and case AND... Titanium instead of white gold, which makes it lighter and more comfortable to wear.
I must say that this last one is my favorite. And that the Constant Escapement is a dream for me. One of the GP I desire the most.
Best,
Nicolas
