One thing I've learned about watches is that I need to take time to maturate what I could have discovered, appreciated and handled in my hands.
My tastes evolve, I have a really soft spot for Independants (these are the watches I started with, together with Lange) but as time goes by I also continue on my way and have a look at what I don't know; Patek, its history and legacy are a part of that.
I don't look at the same things in an indy watch and in a classic brand like Patek. One doesn't necessarily replace the other.
I pay really much attention to details in watches. Some of them (many?) are discovered in the long run.
Then, having worn the watches I own for several years now, I see things that might bother me today and didn't before.
My vision of a successful watch collecting experience is not only assessed by the fact I keep it during a whole life. I may switch to another one on the way by selling one I was happy to own but which brings me less pleasure.
I don't like having too much watches as I wear them everyday. Even today, with around 4, I don't feel I can fully appreciate them as I should.
Today I'm looking at Patek's chrono because I like their look, there design (very different from one to the other), the material, the complication, the movement and what it says about the decade when it was created.
A different pride and sensation for each of them.
This is why I also need time to understand and feel what I really want and what will satisfy me best (which one?), leaving apart the excitation of the moment.
I know what I can let go but not yet what will replace it.
I'm still trying and thinking....
I hope you see a little better what are my motivations Oliver
