Omega Seamaster Aqua Terra 150M 43mm Sedna gold on Sedna gold

This 43 mm Worldtimer model includes a polished case and bracelet in 18K Sedna gold. This is the same material used for the hands and indexes.The exterior section of the opaline silvery dial includes vertical teak stripes and a circle of global destinations printed in red (GMT), blue (+1h in summer) and Sedna gold colour (places without daylight savings).The centre of the dial contains a 24-hour glass ring, with opaline silvery colour to indicate daytime and dark blue to indicate night. The vision of Earth is created on a grade 5 titanium plate. This has been laser-ablated to create the blue ocean, leaving a relief of the continents. The contrasting colours of the Earth’s surface are obtained naturally by the laser’s chemical reaction.Inside, the Worldtimer is driven by the Master Chronometer Calibre 8939.
