This men’s Mühle Glashutte wristwatch is made of stainless steel and scratchproof sapphire crystal. A brilliant combination of electronic and mechanical measurement, it features a tried-and-tested, Mühle-modified, Swiss automatic movement system for keeping time and an altimetre-barometre for measuring altitude and air pressure. It has already been tested successfully on the Mount Everest, where it read 8850 metres — exactly right! Generously donated by F.W. Francis Jewellers.
