Montblanc 4810 Orbis Terrarum Pocket Watch Transatlantic Limited Edition

This is the first time Montblanc has created a pocket watch, and what better occasion than the Maison’s 110th anniversary to introduce such a new timekeeper into the 4810 Transatlantic Collection.  The Montblanc 4810 Orbis Terrarum Pocket Watch Transatlantic Limited Edition not only harks back to the beginning of the 20th century when pocket watches were the timekeepers of choice, but also features the highly appreciated world timer function—the perfect complication for transatlantic travellers.
Setting the timepiece is simplicity itself. The wearer starts by setting the home time zone by pressing the pusher between 5 and 6 o’clock until the home city (or the nearest city indicating the wearer’s own time zone) is positioned in front of the arrow at 6 o’clock.  The hours and minutes are then set via the crown at 12 o’clock, paying attention to turn the hands until the central map features the correct day/night indication. Once complete, the 24 time zones can be easily read at a glance thanks to a large open dial. Travelling is equally simple, as the wearer only has to press on the pusher between 5 and 6 o’clock until the new local time is featured in front of the red arrow at six o’clock. The day/night indicator and the hour hand also advance with each push, requiring no further setting as the home time doesn’t change, keeping track of the time simplicity itself.
Powered by the Calibre MB 29.20, the world timer complication has been developed and assembled entirely in-house by the Maison’s watchmakers. The dial is highly legible thanks to the 53 mm “Lépine” style steel case and a pure design, which leaves plenty of room for the 24 city names. The multilayer dial is crafted out of layers of sapphire crystal showing the continents as viewed from the North Pole. Around the map are the names of the 24 cities representing the different time zones, while under the map a disk indicates the passage of day and night, as well as the 24 time zones. This disk rotates with the movement mechanism, causing the continents to change colour as the day evolves into night.  The size of the disk depicting the globe and the names of the cities is much larger in this 4810 Orbis Terrarum Pocket Watch than it would be in a wristwatch, making it more challenging to turn.  The Calibre MB 29.20, however, was more than strong enough to support the extra size and weight, enabling Montblanc to present this new larger dial aesthetic.

The pocket watch is completed with the addition of a refined steel chain that has been crafted like a ship’s rope, recalling the transatlantic theme and the Maison’s passion for aesthetic perfection and technical performance, just like the luxury cruise liners of the last century that conveyed the innovative spirit of the age.
