This classic yet robust timepiece represents a tribute to OMEGAs 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 sun-brushed and lacquered black dial decorated with the Teak Concept pattern and a date window at 3 o'clock. A scratch-resistant sapphire crystal protects this unique dial. The stainless steel 41. 5 mm case is presented on a stainless steel bracelet. This certified chronometer is powered by the OMEGA Master Co-Axial calibre 8500 which is resistant to magnetic fields greater than 15, 000 gauss and can be seen through the transparent caseback.
