Omega Seamaster Aqua Terra6:10 am
After winning over gravity with the moon watch, Omega notched up their game with a path breaking technology that could protect watches from the effect of magnetism. Launched in 2013, the Omega Seamaster Aqua Terra is constructed of non-ferrous materials that is unaffected by magnetic energy up to 1.5 Tesla(15,000 gauss).
Let us understand first what magnetism is. Most mechanical watch movements are traditionally made of ferrous metal. It means they are susceptible to magnetic field. Exposing a watch to magnetism can cause two major damages. First, the accuracy of the watch is affected majorly and the balance wheel gets shifted by the force. Second, the magnetic field can make the metal magnetized which can destroy the movement (until demagnetised). Certain watch brands before Omega had already designed anti magnetic watches. Rolex came up with the Milgauss which could withstand upto 1,000 Gauss (roughly 1/5th of Omega). IWC came up with the Ingenieur collection which could resist magnetic fields but the unit IWC used for calculation was different.
Omega Seamaster Aqua Terra symbolises a major step in the watch industry as it has broken the standard resistance figures and created a marvel which is above the rest. The watch uses Calibre 8508 movement which is the crux of how the watch is anti magnetic. The use of nonferrous material leads to better accuracy and in turn a longer life span.
The balance spring of the Omega Aqua Terra is made of silicon which is anti magnetic. Another new material used in the 8508 is a material Omega named Nivagauss, which makes up most of the movement’s components and some other small parts. The 8508 calibre is a co-axial movement with a power reserve of 60 hours and is COSC certified. This is one of Omega’s classier looking watches; it is housed n a 41.5 mm case. It has perfect mixture of a polished bezel and a brushed dial. The watch gives water resistance upto 150 m.
The watch supports a date display feature on the dial at 3 o’clock and has stunning yellow highlights to improve readability. It is definitely a great piece of technology and is clearly one of the most desirable pieces by Omega. It is definitely a good choice for people working near high magnetic zones like an aircraft or an MRI machine. The features are attractive and go perfectly with any casual or formal wear. The bold seconds hand might not appeal to all but the anti magnetic feature is something to really look forward to in this watch.
