Chopard Alpine Eagle Stainless steel 41 MM - Stainless steel Bracelet - Sapphire Crystal Dial - 298623-3001

mechanical self-winding movement is based on the first caliber developed by Chopard Manufacture in 1996. It beats at a frequency of 28,800 vibrations per hour (4 Hz) and has a 65-hour power reserve thanks to Twin Technology, a system invented by Chopard that combines two coaxial barrels. The latter represents a remarkable technical feat given the extreme thinness of the movement, which is just 3.3 mm-thick. This movement bearing the Poinçon de Genève quality hallmark is wound by means of a 22-carat gold micro-rotor. Chopard Alpine Eagle Stainless steel case Chopard. see-through sapphire crystal dial.
