Blending innovative technology with timeless Swiss style, the Mondaine Doppio Solar arrives in a 41mm case made from up to 91% recycled 316L stainless steel. Powered by an advanced solar movement, discreet solar cells beneath the dial absorb both natural and artificial light, storing energy in a rechargeable battery that sustains operation for up to 8 months without additional charging. This eco-friendly system eliminates frequent battery replacements and supports responsible timekeeping.

A double-domed sapphire crystal crowns the dial, enhancing the sculpted depth and understated elegance of the concave, light-permeable design. The watch explores the theme of duality through subtle double lines on the hands, indices, and seconds hand tip, complemented by a striking black dial featuring an off-white inner circle contrasted against a bold outer ring.

Built for everyday reliability, it features water resistance up to 5 ATM and a discreet date display. The black strap, crafted from recycled grape leather derived from organic wine production waste, highlights Mondaine’s commitment to sustainable materials. By combining eco-conscious innovation with classic design cues, this model sets a new standard for responsible Swiss watchmaking.
