That doesn't mean shit....it only tells us you don't give a shit about owning a expensive watch.. It got nothing to do with how much money you make in a year...
While it's certainly true that a wealthy person can wear a cheap watch because they don't care, or a lower-income person can wear an expensive watch because they're willing to spend a disproportionate amount of their income on something as trivial as a watch, there is generally a correlation between income and expensive toys.
Now, consider that this being a bodybuilding board, at least half the posters are in their 20's, and are students or people just starting out their careers making less than $50k/year. Basically paycheck-to-paycheck people. If you assume a normal income distribution for the other half, that means fewer than 10% of getbig posters could or should be spending money on a "luxury" watch.
Yet, when asked "what watch do you wear", 100% of respondants claim a Rolex or Breitling or similar. That tells me most of them are lying.
