For a touch of modern elegance paired with advanced complications, citizen’s calendrier women’s watch fits the bill. It has a rose-gold-tone stainless steel bracelet and rose-gold-tone 37mm case, with a white mother of pearl three-hand dial set with diamonds. It uses eco-drive technology, so it is powered by light — any light — and in addition to showing the month, day and date, it also keeps track of the phases of the moon.
