Well thanks for the points of view and the interesting perceptions on motivation ...
It's not so much about lieing but, unless I am mistaken it is essentially illegal (UK) and when considered from that point of view I would probably just tend to avoid answering the question.
With regard to creating an impression, I suppose an element of the desire to have these time pieces is to feel good about wearing it/them. Not sure if that means I would be trying to impress others or not, it certainly is not a concious thing.
It is really intersting that the common view seems to be no one asks, I have up to now just assumed that people notice these things. I will just have to see I suppose.
