We've seen watches that show the time in different time zones, but one that shows the time all the way around the world at once? That's new. And that's exactly what these Montblanc TimeWalker Hemisphere Watches ($TBA) aim to do. In addition to the standard 12-hour face showing the local time, these watches feature a flange around the dial bearing the name of 24 cities, each of which represents a different time zone. A 24-hour disc turns at the center of the dial, corresponding to the cities on the flange. Take your pick between the Northern Hemisphere model, which features cities north of the equator as well as graphics showing the various regions using the North Pole as the midpoint, or the Southern Hemisphere model that does the same for the bottom half of the world.
You don't need to understand the inner workings of the IWC Ingenieur Constant-Force Tourbillon Watch ($TBA) — but it doesn't hurt. It features a patented constant-force mechanism that guarantees extreme precision, as well as two barrels to supply the added torque necessary to drive the tourbillon. Other, more easily understood features include a 96-hour power reserve, a platinum and ceramic case, and a moon phase module that shows the moon phase for both the Northern and Southern hemispheres, as well as a countdown display showing the phases until the next full moon.
