Encelade 1789 Gyro Cufflinks 1797. The two cousins who founded the ENCELADE brand each have their own gyroscope. It was this object, straight from their childhood, that led them to conceive and develop the first gyroscopic cufflink in the world (patented design), comprising 56 elements and no less than 12 ball bearings (a record). It took two years of development and testing to create this technically sophisticated accessory crafted for endless delight. Enjoy being a child again!
