Beyond the Office

Cars
For me, cars are not just marvels of engineering, or art on wheels, but a place where I have time to just think for myself. I also think there is a beauty in driving somewhere without a destination and seeing the world little by little by driving through the landscape instead of flying over it.
Watches
My love from watches stems from all the skilled craftmanship, love and labour that goes into creating a piece that 'just' tells the time. In the digital world that we live in, there is something so pure about a mechanical watch that helps me stay grounded.
Traveling
Having lived in 5 countries, I belive there is something special about experiencing other cultures. That's why I love traveling. Not only do you get to see the world, but you also get to experience and learn something different.
