This 43 mm Worldtimer model includes a polished case in 18K Sedna™ gold, which is integrated with the blue leather strap via a solid polished gold link. 18K Sedna™ gold is also 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.
