This Master Compressor Extreme World Chronograph allows local time in all of the world's major cities to be read instantly on the chapter ring around the dial. In a sturdy 46mm titanium & steel case, a central titanium part protects the movement and separates when subjected to a sudden strong impact, therefore improving shock absorbance. The chronograph is started with a quick twist of the compression keys which keeps the case watertight. Fitted to a JLC black rubber strap and presented with its original personalised JLC box, tag and Certificate of Guarantee. It is waterproof to 100m.
