If you are designing a product that requires any sort of smart-motion precision, spring parts that apply constant force or constant resistance are key mechanical design elements to consider. Two of ...

When master watchmaker François-Paul Journe created his Chronomètre à Résonance timepiece 20 years ago, it was the first wristwatch to ever achieve the phenomenon of natural chronometric resonance ...

Grand Seiko made its debut at Watches & Wonders this spring by debuting its first tourbillon and its most complicated watch ever, the Kodo Constant-Force Tourbillon. It was among the luxury brands ...

Grand Seiko has released its first mechanical complication watch, the Kodo Constant-force Tourbillon, which is the first timepiece to combine a tourbillon and a constant-force mechanism into a single ...

Compliant constant‐force mechanisms represent an innovative class of devices engineered to provide a near‐invariable output force over a defined range of motion. By exploiting the elastic deformation ...
