Not a terribly good analogy. With lenses you pretty much get what you pay for, with a good correlation between price and performance - usually. Watches, not so much. My cheap, and I think good-looking and well-made Lorus wristwatch keeps time to within 3 seconds per month. I'd gain absolutely nothing in timekeeping performance by 'upgrading' to a showy-looking (possibly even tacky) Rolex, Omega or Tag-heur. It would have been a different story in the days of mechanical watches, but not nowadays.
