How many actually know what makes their watch tick?

[d6194m]

From WIS people, you often hear that "I bought it for the engineering/design that went into it." I say that to people who ask me about my Rolex or why someone should buy a Rolex. All I know is that there is a weight that winds the main spring and gives energy to the gears and gears rotate and hands move. But I think and 5 year old can look that up in wikipedia.

And then if someone says "oh, you bought it for the engieering huh? .. OK, tell me about the engineering that went into it", then what do you say?

So my question is that how many people actually know what makes their Rolex tick? or how far does your knowledge go into the gears andthemechanics of the watch?

Or is just saying "I bought it for the engineering/design that went into it" an excuse we make up when we do not know what to say? or we don't know enough but we try to justify our purchase?
