Tsuki-Yomi A-T BY1010-81Z

The Tsuki-yomi A-T combines a moonphase display with atomic timekeeping in a 43mm round case of silver-tone Super Titanium. The deep purple dial is accented with black and silver-tone details, and a moonphase window sits at 6 o'clock. The Eco-Drive caliber H874 powers the watch using light, so no battery is needed. The case measures 10.87mm thick, offering a slim profile.

It comes on a Super Titanium bracelet with a fold-over clasp and push buttons. Water resistance is 100 meters, suitable for swimming and snorkeling. The watch includes moonphase, world time in 24 time zones, perpetual calendar, day-date, and atomic timekeeping via radio control. Stop by Edward Jewels & Watches in Willis, TX to see it in person.
