TAG Heuer has unveiled a luxury smartphone called the Meridiist Infinite.
The handset will ship with a "perpetual power reserve", making use of a solar panel to top up its battery when exposed to direct sunlight.
Made from grade-five titanium and carbon, the Meridiist Infinite comes with a 2.4-inch TFT LCD display (320 x 240) and a high-end monochrome OLED panel.
The device was developed by Atelier Haute Communication in collaboration with Sunpartner Technologies, and features Wysips Crystal Technology behind its display.
Other features include a 5-megapixel rear camera, dual-SIM support and 8GB of on-board storage.
TAG Heuer is yet to announce how much the self-charging phone will cost, but the standard Meridiist handset is priced at more than £3,000.
