Omega is a Swiss watch brand, which belongs to Swatch Group and was founded by Louis Brandt in 1848. Omega's four classic watch series are Constellation, Hippocampus, Motorized Altman and Disc Flying. The last process of his watch has been kept by hand. The latest design mainly consists of coaxial escapement system device, escapement fork with three gems, impact gem on balance wheel and a balance wheel without clamping hairspring. Coaxial escapement system can effectively reduce the friction between gem parts, and keep the watch precise and accurate after long-term operation.
