New Astrodea Celestial Watch from Citizen
"We’ve talked about the Citizen Astrodea “Moon Age” and “Celestial” watch series many times, and it seems we’ll have to keep doing it forever since they update the watches yearly. For those unfamiliar with the line, these are very detailed watches that keep perfect “celestial time” as the face rotates in real time. You can perfectly tell the placement of the stars just by using the watch’s many measurements (which I will never understand completely)."
