Powered entirely by light, the Mondaine essence solar combines iconic Swiss design with modern sustainability. At its heart beats a Swiss Made Ronda solar movement, charging through any light source and running for up to 8 months even in complete darkness once fully charged. The 41mm case is crafted from a renewable castor oil composite, while the black strap features a natural cork lining for comfort. With its crisp white dial, bold black markers, and the signature red seconds hand, this timepiece is both timeless and forward-thinking - designed to last, responsibly.
