Citizen Eco-Drive Radio-Controlled Moon Phase Men's Watch BY1034-59A

Inspired by the cosmos, the Citizen Eco-Drive BY1034-59A brings astronomical innovation to modern dress watch design. Its 42mm stainless steel case is accented with warm gold-tone details along the bezel and pushers, framing a dual-hemisphere automatic moon phase display. Powered by the light-driven Caliber H874, it eliminates the need for battery replacements while automatically syncing time via radio signals for atomic accuracy. Protected by a durable sapphire crystal and built with 100 meters of water resistance, it offers a perfect balance of tech-forward convenience and classic sophistication.
