The purpose of the Tissot Classic Dream is to propose an elegant and classic watch for everyday look at an unbeatable price. The watch is powered by the Swissmatic movement offering up to 3 days of power reserve when most of automatic movements have a power reserve of around 40 hours. This automatic winding movement is regulated by a Nivachron spring with exceptional magnetic resistance. In addition, the dial is dressed with special indexes, split in four parts, giving a unique design to the watch. Nivachron™: Because the magnetic fields generated by our electronic objects (mobile phone, computer, radio, magnetic closure, etc.) are ever more present in our daily lives, Tissot has developed a new, titanium-based alloy at the cutting edge to preserve the precision of its watches. A Nivachron™ balance spring is regarded as far more resistant to and unaffected by magnetic fields than standard springs. Swissmatic Movement: The Swissmatic movement is a true innovation in the watch-making industry. The secret that enables Tissot to offer a model at such an attractive price lies in the automated production chain on which its components are manufactured, then assembled in modules to build a complete movement. The Swissmatic 72 movement offers 72 hours of power reserve, which is enough to tell time accurately even if the watch is not worn for three days.
