Something I did not know before – the baton indices of the limited edition Citizen Eco-Drive Ring launched at Baselworld 2011 are actually Arabic numerals on their side. This detail is visible below if you look closely. The name of the watch stems from the ring-shaped solar cell that circles the dial of the watch. This is also the reason for the open lugs and case side where the solar cell can receive sunlight. Another interesting release from Citizen at Baselworld 2011, the Eco-Drive Satellite Wave. – SJX
