Powered by the Omega caliber 3861, which beats at 21,600 vph and contains 26 jewels, this movement has an approximate power reserve of 50 hours. The watch is METAS Certified Master-Chronometer, passing rigorous tests for water resistance, precision, and magnetic resistance, withstanding magnetic fields greater than 15,000 gauss, and featuring a silicon balance spring and co-axial escapement for optimal performance.
