" This timepiece is powered by light with our proprietary Eco-Drive technology and never needs a battery. The Fio perfectly allows for stacking, mixing, and matching with other timepieces from our collection, pairing well with other Fio models, while still plenty able to stand out on its own. Measuring 18.4mm, the round yellow gold-tone stainless steel case is paired seamlessly with an ultra-slim bracelet for a graceful, luminous presence on the wrist. Distinct lugs and a faceted mineral crystal add sculptural detail, while a crown accented with a subtle red cabochon adds a vibrant touch of contrast. A matching gold-tone sunray dial completes the look, accented with applied indices and sword-style hands. Water resistant up to 30 meters. Caliber G626."
