You have a magnificent watch collection, Mate! That Rolex is spectacular 😍
Personally, I don't have an object that I bought for a significant moment, but I have received several gifts that I still keep, like a Parker pen from my grandfather (his favorite brand when he was a lawyer) and I still have it as a memento for when I graduate soon, or the stethoscope that I use, given to me by the first patient I discharged in the emergency room when I started rotating there.
These are objects that mark important parts of my early life, which I didn't buy personally but hold the same meaning as that beautiful Rolex. In the future, I will follow your footsteps, it a nice way to remember moments that are important to us.
Very good work as always
