Omega Aqua Terra 150M Master Co-Axial Chronometer 38.5 mm Silver Dial (231.20.39.21.02.001)

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 lacquered silvery 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 18K red gold bezel is mounted on a 38.5 mm stainless steel casebody and presented on a stainless steel and 18K red gold 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.
