We haven’t reached the point yet where we can time-travel, but then again, you have to walk before you can run. Watches showing different time zones is nothing new, but Montblanc‘s Timewalker World-Time Hemisphere Watch is very, very different. As its wearer travels across the timezones, they can rotate the brushed titanium bezel and crown to have the watch face show the daytime-nighttime range for the selected zone, indicated by city. Understandably, the Montblanc TimeWalker World-Time Hemisphere Watch is a set of two watches, one for the Northern Hemisphere and one for the Southern, each with its own distinct colorway and a view of its half of the world from above. On the 42mm steel caseback, Montblanc also added what is essentially an engraved cheat-sheet, cleverly listing additional reference points to aid in dialing-in your timepiece. The price begins at $4900, but that’s only for the model in your neck of the woods. You’ll have to buy the other separately to complete the set. Arriving at Montblanc retailers in the coming months.
