Omega Aqua Terra 150M Co-Axial Chronometer 30 mm White Dial (231.50.30.20.55.001)

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 decorated with diamond-set indexes, 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 30 mm 18K red gold case on an 18K red gold bracelet. This certified chronometer is powered by the OMEGA Co-Axial calibre 8521 which can be seen through the transparent caseback.
