Gmt 2 time zone

The Rolex GMT-Master series has been the last word in luxury travel watches for more than six decades. To do so, Rolex borrowed the rotating bezel concept they had introduced on their Gmt 2 time zone a couple years before, marking it with a hour scale, and fitting the dial with an additional hour hand, geared to run at half speed.

Increasing globalisation in the Victorian era meant a need to standardise time zones, as businesses began to operate across wider areas and world travel became easier with the advent of the railway. The Meridian Conference in , attended by representatives from various countries, led to the creation of the 24 time zones we use today. The zones are based on 24 longitudinal meridian lines that run from the north to south poles. The prime meridian, determined by the conference, runs through Greenwich, in the UK, giving us Greenwich Mean Time. Other time zones are counted to the east and west of this line, either plus or minus hours from GMT. Each country sets its own time zone within this framework, so some zones extend beyond the meridian for convenience, while others, like India, take on half hours.

At different times in the past, it has been calculated in different ways, including being calculated from noon ; [1] as a consequence, it cannot be used to specify a particular time unless a context is given. Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt , noon GMT is rarely the exact moment the Sun crosses the Greenwich Meridian [b] and reaches its highest point in the sky there. This event may occur up to 16 minutes before or after noon GMT, a discrepancy described by the equation of time. Noon GMT is the annual average the arithmetic mean moment of this event, which accounts for the word "mean" in "Greenwich Mean Time". Originally, astronomers considered a GMT day to start at noon, [d] while for almost everyone else it started at midnight.

To avoid confusion, the name Universal Time was introduced in to denote GMT as counted from midnight. The term GMT should thus not be used for purposes that require precision. As the United Kingdom developed into an advanced maritime nation , British mariners kept at least one chronometer on GMT to calculate their longitude from the Greenwich meridian, which was considered to have longitude zero degrees, by a convention adopted in the International Meridian Conference of

The contemporary versions of the GMT-Master II, as well as being among the most desirable and difficult to acquire Rolex watches, also have an extremely practical complication for use in everyday life. If you are not used to reading a hour clock, it can take some getting used to; however, those distinctive split-tone bezels are not just for show.

But while the Explorer II can also set its two hour hands independently of one another, the fixed bezel means that it cannot be used to read a third zone.

They can then read the current time normally off the dial, and their home time off the corresponding numeral that the hour hand points to on the bezel.
