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 white mother-of-pearl dial marked with diamond-set indexes and a date window at the 3 o’clock position. The Teak Concept dial is visible through the scratch-resistant sapphire crystal.

The diamond-set bezel is mounted on a 30 mm 18K yellow gold case on an 18K yellow gold bracelet. This timepiece is powered by the OMEGA Co-Axial calibre 8521 which can be seen through the transparent caseback.
