Swiss Federal Institute of Metrology (METAS) certified Master-Chronometer. The finished watch, with its COSC chronometer movement, passes tests that replicate real-life wearing conditions. The METAS certification tests water resistance, precision and magnetic resistance to 15,000 gauss. Anti-magnetic : resistant to magnetic fields greater than 15,000 gauss. Features Omega's Si14 silicon balance spring that improves resistance to shock and magnetism and thus to sustained reliability. The movement also features Omegas Co-Axial Escapement which contributes to greater precision, stability and durability. The Co-Axial escapement has less friction and reduces the necessity of lubrication thus reducing the time intervals required between servicing. The rotor and visible bridges are decorated with a unique "arabesque" wave design finish. Water resistant at 100 meters - 330 feet.
