There are hundreds of years of technology packed into even the simplest wristwatch.
But superluxury watches contain feats of engineering like the tourbillon, invented in 1795, which counters the effects of gravity that make a timepiece imprecise. If you find a Rolex Tourbillon, beware, it's a fake.
It's tempting to wax poetic about art and function coming together, but the bottom line is good watches are cool and they command high prices.
To make this list a watch had to retail for over $100k and have been or currently be in production, not a one-off custom piece. Also, none of them have any diamonds or precious gems. The only jewels on these are in the movements to help them keep precise time over the generations.
