Guess articles of this sort when they attempt to stereotype will always be flawed. Can't say as I really fall into any of those categories. Why G-Shock? Suppose their cool (in an uncool way!), functional, practical and I like the whole Japanese infinite variations.
The other article shows how perceptions differ - I'd rate Timex well below brands like Casio and Seiko.
Tricky one to answer. Why do people collect anything is perhaps the one to ask. G-Shock's are quite collectable I'd say, there's a massive range or styles, designs, colours and editions. They are also relatively cheap (well, compared to Rolex at least).
Mens' (and womens') magazines are IMHO full of marketing twaddle and that's putting it politely. The watches I buy, are selected on my aesthetic tastes, the technology involved, my available funds, the functionality and the intended use I will put them. I don't need a style journo to tell me what is good and what a watch says about me. That would be other peoples' perceptions in any event, and the old adage "You cannot judge a book by the cover is certainly true."
