Introducing the Jaeger-LeCoultre Polaris with a World Time Function

2021.03.18

Jaeger-LeCoultre is a long-established manufacturer that has been leading the world of luxury watches since its founding in 1833. Let's take a closer look at the Polaris, which is equipped with a world time mechanism and is one of the watches in the company's extensive lineup.


What is World Time?

The most important role of a watch is to keep time accurately. The smaller the discrepancy that occurs during use, the better its performance.

However, there are watches that have various functions other than just displaying the time. A world time mechanism is also a highly sought-after feature.

The term "world time" is often heard when reading about watches, but there are probably many users who do not fully understand what kind of mechanism it is. First, let's review what world time is.

Find out the time in major cities around the world

World time, as the name suggests, shows the time around the world. Due to the Earth's revolution and rotation, time differs in each country and region. The common "now" is morning in some places and night in others. While a watch with a simple mechanism only displays the time in one region, a watch equipped with a world time mechanism can simultaneously display the time in multiple countries and regions.

The world time mechanism allows you to instantly know the time in major cities around the world without leaving your home.

Differences from GMT and UTC

If we look more deeply into world time, we come across terms such as "GMT" and "UTC." What is the difference between them?

GMT (Greenwich Mean Time) is the mean solar time at the Greenwich Observatory in London (longitude 0).

Greenwich Mean Time was established in 1884 at the International Meridian Conference held in Washington, D.C. Since then, time zones around the world have been determined based on GMT. Even before 1984, Greenwich Mean Time was widely used by the global shipping industry and North American railroad companies.

On the other hand, UTC (Universal Time Coordinated) is the currently used Coordinated Universal Time. It is a standard time that adjusts the difference between Universal Time, determined by measuring the Earth's rotation, and International Primeval Time, indicated by a cesium atomic clock. Since 1972, it has been managed by the International Bureau of Weights and Measures.

The Earth's rotation period is not constant. This causes a slight discrepancy between Universal Time and International Primeval Time. Therefore, leap seconds are added to International Primeval Time to adjust for the difference with Universal Time.


The Polaris Collection with World Time Functions

Now that we've looked back at the world time mechanism, let's explore the history of the Polaris, which is equipped with this mechanism, and its appeal.

First of all, it goes without saying that the Polaris is a popular collection from Jaeger-LeCoultre that is supported by tradition. Its dynamic yet elegant atmosphere makes it a powerful support for users who travel the world.

60s-inspired design

Memovox Polaris

The 1968 Memovox Polaris was a diving watch with a chiming mechanism. Its rotating inner bezel measured the time spent underwater, and an alarm told the diver when it was time to come out. The triple caseback enhanced the acoustic transmission of the alarm.

The modern Polaris collection is a product of Jaeger-LeCoultre's rich history, with its roots in and inspiration from the Memovox Polaris diving alarm watch from 1968.

Based on manufacturing techniques backed by tradition, the product is finished with a sporty yet elegant feel.

Specially designed straps and bracelets

The strap and bracelet are also specially designed for the Polaris. The bracelet is a three-piece design with alternating satin and polished finishes, creating a flexible fit.

Additionally, the watch is available with an interchangeable alligator or calf leather strap, featuring a new folding clasp with a graphic design to match the exquisitely finished case.

Shows the time in 24 cities

The Polaris collection has a lineup ranging from simple automatic watches to chronographs and the full-fledged diver's watch, the Mariner Date, but the WT (World Time) model has a function that allows you to read the time in 24 major cities around the world.

The time is adjusted using the crown at the 10 o'clock position. The watch also supports daylight saving time, and cities that use it are marked with a white triangle, allowing you to read the exact time adjusted by one hour.

Three Polaris Chronograph WT models

The Polaris Chronograph WT is a popular model with two subdials balanced within the dial. We will explain the three models in this collection.
