MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611024046 A) filed by Chandigarh University, Mohali, Punjab, on Feb. 28, for 'hybrid solar-electric motor assisted mechanical wristwatch with automatic spring winding.'
Inventor(s) include Ayush Kaushal; and Harsh Sharma.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a hybrid solar-electric-mechanical wristwatch that integrates renewable solar energy with classical mechanical timekeeping. A transparent and semi-transparent photovoltaic dial captures light from sunlight or artificial sources and converts it into electrical energy, which is stored in a rechargeable micro-battery or supercapacitor. A low-power microcontroller intermittently activates a micro-coreless DC motor with a reduction gearbox, which drives a clutch and ratchet mechanism to wind a mechanical mainspring. Torque sensing, current monitoring, and slip clutch mechanisms prevent overwinding and protect mechanical components. The watch preserves the tactile, auditory, and visual experience of mechanical timepieces while operating autonomously, eco-efficiently, and with minimal maintenance, providing a sustainable and self-sufficient solution for modern horology."
