How does it go again? Do I set my watch forward or back on my way to China? Is my business partner in Dubai awake or asleep? A world-time watch can answer all such questions.

The pilots’-watch look of the IWC Pilot’s Watch Worldtimer conveys both the reason and need for this kind of timepiece. Pilots orient themselves solely on the coordinated world time known as UTC. The Worldtimer is the obvious next step in development from the 1998 IWC pilots’ replica watch and its second time zone – helping travelers who quickly move through different time zones keep their home time in mind. It can also help managers keep track of business partners in various locations around the world.The Worldtimer has maintained the look of a typical cheap iwc replica with its white numerals, markers and hands, clear minutes track and prominent triangular orientation marker at 12 o’clock. The matte, black background improves legibility, and luminous material on essential elements means you can read the watch in the dark. The elongated date window is new, as are the city and 24-hour day/night rings for the world-time function. Both adhere to the black-and-white pilots’-watch design code and are just as easy to read as the time. The case is 45 mm in diameter and has a nonreflective sapphire crystal.The Montblanc Heritage Spirit Orbis Terrarum gives a very different view of world time. Its perspective originates, as its name suggests, from our big, blue planet – to be precise, our big, blue planet as seen from the iwc replica watches. It’s hard to escape the sense that you’ve seen this somewhere before. Right – it was the Patrimony Traditionnelle from Vacheron Constantin. Impossible to think otherwise. The Patrimony was quite similar in its approach, but according to Montblanc, the world-time module is of its own design and is distinguished by the arrangement of the disks, the number of time zones and its mode of operation – in this case via a pusher at 8 o’clock instead of a crown like the Patrimony.

The watch makes a good first impression. The center of the dial offers a beautiful view of earth from above. The names of 24 cities, representing the different time zones, encircle the dial on a white ring. The 24-hour ring, with a day/night division, is outside the city ring. It’s fascinating to iwc replica the shifting dark-blue section of the dial as it shows the nighttime hours between 6:30 pm and 6:30 am.To align the time and location, you first use the pusher at 8 o’clock to position the desired “home town” with the tiny red triangular arrow at 6 o’clock. For example, Mountain Standard Time would use Denver. Then the time is set using the crown by pulling it out to the middle position to adjust the hour in one-hour increments. The city ring can now be used to read the time in different time zones. If you travel to another time zone, the pusher at 8 o’clock can be used to bring the correct city into alignment with the red arrow at 6 o’clock. The hour hand will “travel” along and the relations between the different time zones remain unchanged.The home time is read from the city ring and the new local time is read from the two center-mounted, faceted dauphine hands. Unfortunately, none of this can be seen in the dark, and even in daylight the legibility of the Heritage Spirit Orbis Terrarum is not as good as that of the iwc replica watches.
