Omega Aqua Terra 150M Master Co-Axial Chronometer Ladies’ 38.5 mm Grey Dial (231.13.39.21.57.001)

Description

The Aqua Terra Ladies Master Co-Axial features everything that a luxury timepiece deserves.

First to catch the eye is an astonishing Tahiti Mother of Pearl dial that sits within the stainless steel case. The shimmering effect is further enhanced by 11 diamond indexes that deliver superb elegance at every hour, as well as a date window at 6 o’clock.

The slender hands are rhodium-plated with a white Super-Luminova coating, while the grey leather strap features a polished foldover clasp.

In this model, beauty also runs deep. At the heart of the watch is the OMEGA Master Co-Axial Calibre 8500, featuring revolutionary anti-magnetic technology.
