Omega was founded in 1848 but has not, amazingly enough, produced a watch with a world-time complication in its century-and-a-half-plus history — until now. The Omega Seamaster Aqua Terra Worldtimer Master Chronometer, limited to just 87 pieces worldwide, is the crown jewel of the Swiss brand’s redesigned Aqua Terra collection and features yet another new Master Chronometer-certified in-house movement.
The eye-catching dial of the Aqua Terra Worldtimer consists of two levels. The first is an exterior section made of a sand-blasted platinum-gold alloy, with applied yellow-gold indices treated with Super-LumiNova and a two-row circle printed with the names of world cities in three distinct colors. Red is used only for London, representing GMT 0; black, for locations with daylight savings or summer times; and blue, for locations without daylight savings times. The GMT +1 time zone is represented by Bienne, Switzerland, the hometown of Omega.
The dial’s second, interior level is a central sapphire disk, with a hand-crafted enamel world map as seen from the North Pole and an outer ring with a 24-hour indication in day and night color segments. The hands traversing the dial are also made of yellow gold and coated with Super-LumiNova; the date appears in a window at 6 o’clock.
The case is constructed of the same platinum-gold alloy as the outer dial, measures 43 mm in diameter, and features a combination of polished and brushed surfaces. The wave-edged design of the exhibition caseback, a hallmark of the revamped Aqua Terra collection, is highlighted by a number of engravings, including the watch’s limited edition number (xx/87).
Inside ticks the movement, Omega’s self-winding Caliber 8939, the latest in the brand’s growing portfolio of Co-Axial Master Chronometer calibers. To be designated a Master Chronometer, the watch and movement must achieve the highest standards of precision, performance and magnetic resistance as determined by the Swiss Federal Institute of Metrology (METAS).
The Omega Seamaster Aqua Terra Worldtimer Master Chronometer Limited Edition is water-resistant to 150 meters and is mounted on a brown leather strap with contrast stitching and a foldover clasp in platinum-gold. It will be available at retail in December 2017, priced at $48,600.
