Seamaster Aqua Terra 150M Co‑Axial Master Chronometer GMT Worldtimer 43 mm
Steel on steel
This 43 mm Worldtimer model includes a polished case and bracelet in stainless steel.
The exterior section of the dial is sun-brushed blue and includes vertical teak stripes and a circle of global destinations printed in red (GMT), silvery (+1h in summer) and blue (places without daylight savings).
The centre of the dial contains a 24-hour glass ring, with light blue 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 8938.
