The Omega Seamaster Aqua Terra represents a fine mix between sports and elegance. It's refined yet robust -boasting a water resistance of 150 meters- and its signature elements include the dial inspired by the wooden decks of luxury sailboats, the twisted 'lyre' lugs, and a distinct hand set.The present model holds an additional suprise: its Omega in-house co-axial movement features an annual calendar complication.As reference 231.50.39.22.02.001, the Aqua Terra Annual calendar features a red gold case and matching bracelet. The dial is silver.
