● Model number: E610-S104831・AT3034-57E ● It appears to have been sold by Japanet for 63,000 yen in January 2016. ● This is a radio-controlled watch that charges via solar power and automatically corrects the time and calendar using radio waves. Manual correction is also possible. ● It is in working order, and both radio reception and charging functions are good. ● Both automatic radio reception and forced radio reception are successful, displaying the correct time. (As it is a radio-controlled watch, even the second hand is perfectly aligned.) ● Although I have taken the time to confirm its operation, there is a possibility of unforeseen issues, so if there is a malfunction within one week, I will sincerely respond with a return and refund. ● Luminous hands and markers. Diameter approximately 4.7cm including the crown, thickness 13mm. ● There are no scratches on the sapphire crystal glass. ● Wrist circumference approximately 18.0cm (spring bar type, so it can be replaced with a commercially available belt). ● Both the case and belt are made of steel. ● There are fine scratches on the back cover and belt that do not appear in the photos. ● 20-atmosphere water resistance, but it is not a diver's watch. ● A copy of the instruction manual is included. Manufacturer's Excerpts: ● Light-powered "Eco-Drive" is Citizen's unique technology that converts sunlight and even the slightest indoor light into electricity to keep the watch running. ● The world's first analog chronograph radio-controlled watch. This is a full-fledged chronograph model equipped with a 1/20-second chronograph, alarm, local time, and perpetual calendar functions. ● A watch that is resistant to shocks and magnetism, and does not shift. The unique technology "PERFECTEX," which integrates three functions: "JIS Class 1 magnetic resistance," "shock detection function," and "needle automatic correction function," prevents the watch hands from shifting due to magnetism or shock.
