Since I bought an Eco drive citizen CITIZEN (シチズン) 腕時計 PROMASTER プロマスター マリン Eco-Drive エコ・ドライブ PMX56-2812 ペアモデル メンズ which I love much. I decided to buy another Eco drive Citizen for my girl friend so that we will make a couple. It was the STILETTO. CITIZEN (シチズン) 腕時計 STILETTO ステレット Eco-Drive エコ・ドライブ SIR66-5161 レディース. This is a slim and pretty watch suitable for lady. My girl friend was very happy to have it. It really makes a perfect couple with my Promaster.
