Seamaster Aqua Terra Worldtimer 150M Rio

This 43 mm Worldtimer model features a polished 18K Sedna™ gold case and bracelet. This material is also used for the hands and indexes.

The outer section of the opaline-silver dial features vertical teak stripes and a circle with worldwide destinations printed in red (GMT), blue (+1h in summer) and Sedna™ gold (locations without daylight saving time).

The center of the dial contains a 24-hour glass bezel, with silver-opaline indicating day and dark blue indicating night. The view of the Earth is created on a 5 grade titanium plate. Laser ablation was used to create the blue ocean, creating a relief representation of the continents. The contrasting colors of the Earth's surface are produced naturally by the chemical reaction of the laser.

Inside, the Worldtimer is powered by the Master Chronometer caliber 8939.
