Is the Omega Constellation 8500 movement a silicon hairspring?

Yes The new generation of 8500 coaxial movements and these coaxial movements are equipped with Omega Si 14 silicon hairspring. The latest design is mainly composed of coaxial escapement system device, escapement fork with three gems, impact gem on balance wheel and a balance wheel without clamping hairspring. The design and use of this dial system need exquisite professional technical support and perfect watchmaking experience. The use of coaxial escapement system greatly reduces the risk of deformation of hairspring due to vibration. Therefore, the stability of the regulating system can be continuously enhanced and maintained. The coaxial escapement system and the balance wheel without clamping hairspring complement each other.
