Citizen Silhouette Eco-Drive Women's Watch vs Citizen Bianca Eco-Drive EW5602-57D

Both are small gold-tone Citizen Eco-Drive watches that never need a battery. The Silhouette EM0862-56D is the dressier pick: a 25 mm case, crystal-set bezel and bracelet, and a mother-of-pearl dial. The Bianca EW5602-57D is smaller at 21.5 mm and steps up to curved sapphire crystal and blue hands on a clean white dial. Buy the Silhouette for sparkle and presence, the Bianca for a tougher crystal and a more understated look.

• Choose the Silhouette if you want a jewelry-style watch with a crystal-set bezel and bracelet and a mother-of-pearl dial.
• Choose the Bianca if you want a smaller, cleaner watch with scratch-resistant sapphire crystal and blue hands.
