Datezoner Pilot

The uniqueness

Date and time zones are synchronised

The DATEZONER is the only watch in the world to change date and time zone via the bezel. This unique mechanism is patented and ensures that the date changes automatically when the hour hand is moved over the midnight line via the bezel, bothe clockwise and counter-clockwise. As a result the BIG DATE at 6 o'clock is easy to read and displays always the right date in every time zone.

The bezel

IATA Metropolitan Codes engraved on the bezel

The bezel is engraved with UTC and all major metropolitan IATA codes. The outer circle is used for the period from March to October and the inner circle from November to February. Eventually, both circles will automatically account for changes of summer time (daylight saving time) in the northern hemisphere AND in the southern hemisphere which changes to DST in the reversed way on!

Note that the Vogard remains the only manufacturer to produce a time zone watch that accounts for daylight saving time and that offers bezels personnalised with the cities or airport codes of your choice.

The DATEZONER's ingenious method of timezone adjustment remains unaltered from that used on the original Vogard's models - in other words, just open the locking lever at the side of the case and rotate the engraved gold bezel so that the city relevant to the required time zone is at 12 o'clock. The lever is then closed and the watch is now securely set to local time.

The hands

Skeletonised Hands with Strontium-Aluminates

The DATEZONER PILOT is equipped with extra large skeletonized hands in order to read all instruments instantely. They are covered with Strontium-Aluminates to make the time readable as well in darkness or at any flight level. This material is known for its extra strong fluorescence.

The secret

A synchronisation wheel

The link of the time zone with a disc to change date is a world first in the history of Swiss mechanical watch making. This ingenious solution became possible thanks to the development of a complex, angled synchronisation wheel which is activated by the timezoner movment on one side and which meshes with one of the 31 knops on the bottom side of the date disc on the other side.

The calculation of the exact angle for the positionning of the synchronisation wheel on an inclined plane is a secret known only to Vogard's engineers.
