Among others, all models of Longines' brand new Spirit collection are fitted with cutting-edge movements that include a silicon balance-spring. Silicon is lightweight material which is resistant to corrosion and is unaffected by normal temperature variations, magnetic fields, and atmospheric pressure. Its unique properties enhance a watch's accuracy and longevity.
The exceptional performance and accuracy of the watches of the new Longines Spirit collection are independently verified by their certification by COSC - the Official Swiss Chronometer Testing Institute - as chronometers.
"At Longines, we strive for watchmaking excellence and customer satisfaction," said Matthias Breschan, CEO of Longines. "An efficient and first-class customer service is part of the brand experience. All of our recent technical advancements have enabled us to introduce this new five-year warranty, for all models with silicon balance spring, demonstrating that our quality standards are continually improving."
