Aqua Terra 150M Co-Axial Master Chronometer GMT Worldtimer 43mm

Description

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.
