Description

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. Thirty-minute and 12-hour recorders, and a small seconds dial can be found at the 3, 6 and 9 o’clock positions, respectively. A scratch-resistant sapphire crystal protects this unique dial. The bezel is mounted on a 44 mm stainless steel case on a black leather strap. This certified chronometer is powered by the Co-Axial calibre 3313 which can be seen through the transparent caseback.
