This channel is about watches. I like watches, but I am no expert or collector and everything I say is just my personal opinion. I just simply had an idea of having fun by running a youtube channel about my experience with the watches I buy. So I set the budget of a 1000 euros and started the channel. This is why I flip most of my watches, because I have to stay within my budget while introducing new watches to the channel. And that is why all the watches you see on this channel are the cheap ones as well.
