Omega Seamaster Aqua Terra 150M Co-Axial Annual Calendar 38.5mm – stainless steel chronometer with annual calendar complication.
This refined sports-luxury timepiece merges technical sophistication with understated elegance through its signature Teak Concept dial and annual calendar functionality. The silver dial, engraved with horizontal teak-inspired grooves, provides a distinctive textured backdrop for applied index markers and rhodium-plated hands. Powered by the COSC-certified Co-Axial caliber 8601, the movement automatically adjusts for months with 30 and 31 days, requiring manual correction only once per year on March 1st.
