Tag Heuer Carrera Mikrogirder Watch
If you need a watch that's so precise it can keep time down to a tiny fraction of a second, you need the Tag Heuer Carrera Mikrogirder Watch ($120,000). Representing the complete reinvention of mechanically-regulated watch movement, this timepiece measures time down to a ridiculous 5/10,000th of a second — so you'll never have to worry about missing a beat. The watch comes on a hand-sewn anthracite soft-touch alligator bracelet, with a polished and brushed black titanium carbide coated steel case, a sapphire crystal, and an anthracite and silver dial.
