Watch Promaster Brand Watch 100th Anniversary Limited Model Eco Drive Radio Controlled Watch Waterproof Black [Citizen] "CITIZEN" BY3005-56E Men's

[LAYERS of TIME] In 1924, we created our first product, a pocket watch. The theme of the cross-sectional project that will appear in this milestone year, 100 years since then, is "LAYERS of TIME". Using Fujifilm Corporation's structural color ink, the dial is decorated with a design reminiscent of the beautiful interior scenes created by the Earth over time, such as geological formations and minerals. [PROMASTER, a full-fledged sports watch that can withstand harsh environments] A subtle black gradation is added to the back of the dial using inkjet technology, creating a rich expression. The unified white hands and indexes serve as accents that highlight the brilliance of the structural color and add a refreshing impression. The back cover is engraved with a distinctive map layout, making this a watch that allows you to experience the sky and the earth at the same time. [Citizen's radio-controlled clock that keeps accurate time at all times] Equipped with Citizen's proprietary light-powered Eco Drive technology that eliminates the need for regular battery replacement. A world time radio clock that synchronizes to accurate time no matter where you are. It is packed with radio-controlled clock technology that Citizen has been challenging for 30 years.
