Buying the cheapest Casio can also be a status signal, similar to the CEO of Goldman Sachs wearing a Swatch. Buying a truly cheap watch is a signal of 'I don't care' (which may be true, or may be affected), whereas getting into expensive watches can get very complicated. There's plenty of stories from investment banking about the signals that watches send, from my understanding people are more likely to poke fun at a Tag Heuer than a Casio.

Signalling is not problematic itself, it's the unnecessary cost of signalling.

Signalling with low price saves money and time. It's a good thing.

It depends whether the watch is made in China or Japan, but you would have to make the owner to take it off :-)

It is also a lot less likely to lead to you being mugged.
