The Citizen Eco-Drive 365 Series timepieces have been shown off as some of the latest models from the brand that harness the style aesthetic of the 1970s and marry it to some of the latest technological innovations.

The watches are each integrated with a solar-powered movement inside that will deliver up to one-year of use on a full charge, which doubles the standard battery life of the brand's Eco-Drive battery. The movement is rated to be accurate with plus or minus 15-seconds per month to make them suited for discerning wearers.

The Citizen Eco-Drive 365 Series timepieces feature angular 42.5mm cases in three colors including black ion-plated, gold with four lab-grown rubies and a steel version with a black bezel.
