Citizen Tsuki-yomi A-T Atomic Timekeeping / Super Titanium™ BY1010-57H

Tsuki-yomi takes its name from the Japanese moon deity, and this Citizen makes the Moon more than a decorative motif. A moonphase display at 6 o'clock shows the current lunar phase, while the textured gray dial recalls the Moon's surface. The watch combines that display with radio-controlled timekeeping, a distinctive pairing in Citizen's 30th-anniversary model.

The 43 mm silver-tone Super Titanium case and bracelet are paired with a sapphire crystal. Citizen's light-powered Eco-Drive caliber H874 offers world time across 24 time zones, a perpetual calendar and day-date displays alongside the moonphase. Radio time-signal reception can automatically correct the time and calendar in supported reception areas. Water resistance is rated to 100 meters.

Our Take

The gray lunar-textured dial makes the moonphase feel like part of a coherent design rather than an added complication. It's a compelling choice for someone who wants both a visible connection to the Moon and substantial everyday timekeeping functions.
