A novel concept that captivates light from the sides of the case

Eco-Drive RING was first introduced as a concept model in 2009. CITIZEN’s continued efforts have resulted in perfection in watch face design, features and details. In 2012, CITIZEN is proud to present the limited edition of 250 pieces worldwide.

Turning convention on its head, Eco-Drive RING captures light not from the face but from the sides of the case, turning a once-peripheral component into a centrepiece of the watch’s design. A radically new concept in watchmaking is born, fusing light power generation with design elegance.

The design demonstrates the considerable thought given by CITIZEN to the side view. Seen head-on, the design appears simple. Its unique features are revealed when the watch is observed from an angle.

The side of the case, with a modern, architectural motif.

The ring-shaped solar cell, encompassing the sides of the case, is embellished with a coin-like edge, overlaid with curved sapphire glass. Previously hidden away inside the case, the light-catching structure now takes its place as a signature design element. The distinguishing hollowed lugs design is born out of necessity, to maximize light absorption from the sides.

The stylish, high-quality finished dial

The dial features the three-dimensional hour markers that appear as simple bars when viewed from above, but reveal themselves to be the Arabic numerals when seen from an angle. Clear parts embedded with the sub dials at 6 and 12 o’clock to create a transparent, three-dimensional appearance.
The uniquely designed　moon phase at the 6 o’clock sub dial is indicated by covering and uncovering the moon by the shadow casted by the sun.

The pearl-coated, blue-grey strap

The pearl-coated, blue-grey strap coordinates beautifully with the silver tone of the dial for a feel of freshness And brightness, and is finished with crocodile leather, thick-stitched for a solid, high-quality look and feel. Like the case, dial and lugs, the buckle adopts the hollow design.
