IWC International Watch Co., Schaffhouse

European Watch Clock and Jewellery Fair 1991 BF 238
Available for 15 years now, the double-back IWC watch, based on a design by Ferdinand A. Porsche and incorporating both a watch and a compass, is now available with titanium body. It naturally continues to boast a precision selfwinding movement and the hinge feature that allows the watch to be placed at a 45° angle so the case back can double as a mirror and as a sighting device. Both the watch and the compass are water-resistant down to 30 m. Its bracelet links are precisely 5 mm wide and can serve as measuring unit for map readings.
