If I like the look of a watch I will generally take a leap and buy one. I am no purist, but on the whole have been happy with the purchases made, even though I am well aware of most of their flaws. I have 14 in my collection so far, and all get regular outings (all except one that is ).
And, I love tearing them apart to see how they are put together. It's fun trying your hand at modding too.
