Originally introduced at SIHH in 2011, the Patrimony Traditionnelle World Time is now available in platinum. The new model is essentially a platinum version of the original Traditionnelle World Time — with two notable distinctions.

First, is the beautiful new hand-engraved platinum world map in the center of the dial (with a shaded area on the map to reflect day or night). Second, is that the dial now reflects the upcoming time zone change in Moscow, from three hours ahead of Geneva, to two hours ahead (effective on October 26, 2014).

Apart from the changes we mentioned above, and the new platinum case, dial, hands and clasp/strap threads, everything else is the same as the original.

Is has 37 world time zones — including those offset by half-hour or quarter-hour. And it is still powered by self-winding caliber 2460 WT, which is protected by three patents: for the indication of 37 time zones, for the day/night indication, and for crown-operated adjustments.

The case is 42.50 mm in diameter and is made of 950 platinum, as are its dial and its folding clasp. This timepiece, bearing the prestigious Geneva Seal, is issued in a 100-piece limited edition.
The retail price is $98,500.
