At the heart of this 28 mm OMEGA model is the long-life caliber 4061 movement to maximize battery life. Its spectacular stainless steel design is characterized by a striking sky blue dial with 18 Ct white gold indexes and appliques. To create an exclusive contrast, OMEGA has highlighted the engraved Roman numerals and bezel details in pastel tones. As an iconic timepiece, this OMEGA ladies' watch features the Constellation Observatory medallion stamped on the case back.
