How much of a Nintendo fan are you? Enough that you could spend as much as you would on a car, just to show the world where your allegiances lie? You'll want to talk to luxury watchmaker Romain Jerome, then. It just unveiled a limited edition Super Mario Bros. mechanical timepiece that marks the 30th anniversary of the plumber's adventures in style. And we do mean style: its 46mm case is made out of black titanium, and the three-layer dial is loaded with enamel-coated pixel figurines to remind you of Mario's early days. It's quite posh-looking, then, although the eye-watering $18,950 price will likely rule this out unless you're a high roller with some fond gaming memories. On the plus side, that ultra-rare Nintendo World Championship cartridge suddenly seems like a bargain.
