The Triple Complication GMT, with sporty and gem-set
options, is cased in palladium. Note the separated date
windows.



 
The unusual metal palladium owes its name to Pallas, the Greek goddess of wisdom and a patron of the arts and sciences. The origin and history of palladium are very closely bound up with those of platinum and other related metals. In their present form they have a long history. In ancient Egypt and pre-Colombian Latin America these metals and their alloys were already important.
    The modern discovery of these metals is attributed to the Spanish conquistadors of the seventeenth century: the name is derived from the Spanish word "platina," meaning small silver. Palladium the element was discovered in 1803 by the Englishman William Wollaston. The production of platinoids calls for extremely complex conversion techniques in the refining process, while their very high melting temperature makes it a difficult task to obtain a finished product like the new Triple Complication GMT. With this new piece, DeWitt joins a short list of firms using palladium for watches, including Harry Winston, Ulysse Nardin, Cartier and Parmigiani Fleurier.
DeWitt devised the constant force device, essentially a kind of inertia flywheel, that absorbs once every second the force delivered by the mainspring, and redistributing it once every ten seconds to the tourbillon.
This principle is seen through the constant force window on the dial in the form of a cross that is terminated by four hammers that rotates six times every minute.
The DeWitt-patented device is its own mainspring, which 		ensures that the movement’s mainspring always has more energy than is needed by the tourbillon regulator.
As you can see on our cover, the dial is gold, as are the hands and indexes.
The 43 mm case is the firm’s Imperial Column style, available in white gold or rose gold. Like the new Triple Complication GMT (see above), this edition is also made with a gem-set option.
While DeWitt continues to develop a seriously innovative series of in-house movements, with its new silicon dials and use of gems and palladium DeWitt ensures that its high-tech developments look just as good from the outside as from within.
