The blue-dial Tsuki-yomi A-T pairs Citizen's moonphase display with radio-controlled timekeeping. Its name references the Japanese moon deity, while the dial's surface-inspired texture and moonphase window at 6 o'clock give the lunar theme a physical presence. This model belongs to Citizen's 30th-anniversary Tsuki-yomi launch.

A 43 mm silver-tone Super Titanium case and bracelet surround the blue dial beneath a sapphire crystal. Light-powered Eco-Drive caliber H874 provides world time across 24 time zones, a perpetual calendar, day-date displays and the moonphase. In supported reception areas, radio signals can correct the watch's time and calendar. Water resistance is rated to 100 meters.

Our Take

The blue dial makes the lunar design feel cooler and more contemporary than the gray version. Both share the same practical complications; the choice is really about which interpretation of the Moon you want to see on your wrist.
