With the world-renowned appearance of the Omega Seamaster Aqua Terra GMT watch, a new member of the Omega family of coaxial movements was born, which is the new 8605/8615 coaxial movement. Omega 8605/8615 coaxial movement is the first Omega in-house coaxial movement equipped with GMT complex functions. That is to say, in addition to the central hour hand, minute hand and second hand, the watch also has GMT hands, every 24 hours One rotation makes it possible to read the time of two places at the same time.
The 43 mm diameter case is available in 18K red gold, stainless steel, and red gold with stainless steel. With the screw-in sapphire crystal case back, the perfect operation of the Omega’s extraordinary coaxial movement is clearly visible. The watch comes with a metal bracelet of the same material as the case, or a black, brown, or blue leather strap.
The Aqua Terra GMT watch uses the iconic ‘Teak Concept’ dial of the Aqua Terra watch, whose vertical texture is reminiscent of the teak deck on a luxury yacht. Frosted and polished 18K gold hour markers are coated with a white luminous coating. The arched hands are made of 18K white or red gold and are also covered with a white luminous coating, which can easily read the time under any light conditions. The red arrow at the end of the GMT hand makes it easy to identify the time between the two places.
At the heart of the Aquamar GMT watch is the Omega 8605/8615 coaxial movement. In 2007, Omega designed and produced the brand’s own coaxial movement around the first practical new escapement system in 250 years, the ‘mdash;’ coaxial escapement, ‘mdash;’ New member of the coaxial movement family. The coaxial escapement in the movement is used in conjunction with the cardless balance spring, which is very different from the traditional lever escapement system with fast and slow clips. The vibration frequency of the watch can be adjusted by changing the moment of inertia of the balance wheel. This adjustment can be achieved by two 18K gold fine adjustment screws on the balance wheel. This design avoids the interference caused by the contact between the balance spring and the speed clip, thereby ensuring that the coaxial escapement brings long-term stability to the watch. Reduced friction means that the need for lubricants is basically eliminated, so the coaxial movement has a longer maintenance cycle. The Omega Seamaster Aqua Terra GMT watch is also equipped with a silicon hairspring and enjoys a warranty of up to 4 years.
The Omega 8605/8615 coaxial movement is the first movement in the Omega family of coaxial movements equipped with GMT complex functions. GMT hands with shiny red arrows make it easy to read another time zone or Greenwich Mean Time. Interestingly, the GMT hand can also be used as a compass orientation: in the northern hemisphere, the watch is placed horizontally, the hour hand and the 24-hour GMT hand are adjusted to the local time, and the hour hand points to the sun. .
