For a touch of modern elegance paired with advanced complications, Citizen's Calendrier women's watch fits the bill. It has a pink gold-tone stainless steel bracelet and pink gold-tone 37 mm 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. Water resistant to 50 meters.
