Vacheron Constantin Patrimony World Time with all time zones

Until now there was no wrist watch telling time in all time zones on planet earth. The new Vacheron Constantin Patrimony World Time is the first wrist watch able to tell the time in all 37 time zones.

There are many wrist watches with a second time zone or GMT complication. They all have one thing in common and that is they can only indicate time zones with steps of a complete hour. But there are more than just 24 time zones on our planet! Some with an offset of half hour and even timezones with an offset of only a quarter of an hour! The new Vacheron Constantin Patrimony World Time is the first wrist watch that does justice to every time zone we know.

The display consists of three dials: the central disk displays a so-called  “Lambert projector” map and city names. Above the map, a sapphire disk shaded on one side indicates day and night. The outer metal chapter ring bears the minute track and applied hour markers.

The display allows simultaneous read-off of the time in all regions of the world, along with the day/night indication provided by the central world map. All indications are adjusted via the crown.

How it works? Well, the wearer chooses the reference time and places it opposite the black triangle at 6 o’clock. The time in the reference location can then be read off either by the hour hand, or by the 24-hour disc, while the time in the other 36 time zones is simultaneously readable. The cities shown in black represent the full time zones, while the cities in red indicate half-hour or quarter-hour zones.

Inside ticks Vacheron’s new patent-pending Calibre 2460WT, of course in-house designed, developed and manufactured and bearing the Geneva Seal. The relatively large (36.6mm) automatic movement has 255 components (of which 27 jewels) beats at 28,800 vph and has 40 hours of power reserve.

The 18K pink gold case measures 42.5mm in diameter and is water resistant up to 30 meters. A sapphire display back offers a view of the movement. The brown alligator leather strap is secured by an 18K pink gold folding clasp.

Vacheron Constantin has said that as new time zones are created, they will have the ability to update the movement. And if you prefer a white gold version, this will most likely be released within the next two years. The retail price is $39,900.

    Time zones around the world are 40 not 37.

    25 of them with steps of a complete hour,
    13 with an offset of half hour and
    2 with an offset of three quarter of an hour,

    but there is not time zone with an offset of only a quarter of an hour.
