Omega Omega Seamaster Aquaterra Co-Axial Watch. This classic yet robust timepiece represents a tribute to OMEGA’s rich maritime heritage. The dramatic and easily-recognisable dial design of the OMEGA Seamaster Aqua Terra 150M collection recalls the wooden decks of luxury sailboats. This model features a black dial decorated with the Teak Concept pattern and a date window at the 3 o’clock position. A scratch-resistant sapphire crystal protects this unique dial. The bezel is mounted on a 38. 5 mm stainless steel case on a black leather strap. This certified chronometer is powered by the OMEGA Co-Axial calibre 8500 which can be seen through the transparent caseback.
