Citizen Calendrier BU0054-52L 44mm – two-tone moonphase watch with comprehensive calendar display and Eco-Drive solar technology.
This timepiece integrates four independent complications within a balanced dial layout, tracking lunar cycles alongside month, day, and date through dedicated subdials. The Eco-Drive caliber 8730 eliminates battery replacement by converting any light source into stored energy, while the two-tone construction pairs polished gold-tone accents with brushed stainless steel for dimensional contrast. At 170 grams, the substantial bracelet weight reinforces quality perception.
