It has a “grand feu” fire-baked enamel dial, platinum case, a worldtimer movement, and is limited to only 87 pieces, the latter of which is maybe the most interesting as Omega typically makes their limited editions in the thousands.
Like the case, which is 43 mm in diameter (21 mm interlug width), the dial is also crafted from solid platinum the has a sandblasted surface and that is contrasted by 18K yellow gold hands and indexes.
The main dial chapter ring features 24 reference cities transfers and is fixed in place. In the center, is a 24-hour rotating center disc that indicates the home time (or a second time zone of your choice), along with a map and day/night indication.
Notably, Paris (or Geneva) is typically used to represent GMT +1 but in this instance, Omega chose to use the city of their headquarters: Bienne.
Inside is Omega caliber 8939, which is a Master Chronometer movement, meaning it is resistance to magnetism up to an astounding 15,000 Gauss. This movement beats at a unique frequency of 3.5Hz (25,200 vph), features Omega’s signature Co-Axial escapement, and has a 60-hour power reserve. Being that this is a precious metal watch, the balance bridge and winding rotor are in 18K red gold.
The Seamaster Aqua Terra Worldtimer Master Chronometer Limited Edition retails for $48,600 and it will be available in December 2017, exclusively at Omega boutiques. Water-resistance is 150 meters. (Ref. 184.108.40.206.99.001)
