The Spitfire Chronograph from IWC Schaffhausen has been a hit since its debut in 2006. Now, with a cool slate-colored dial, it's even more stylish. The watch boasts the IWC-manufactured 89365 calibre, giving it a longer power reserve of 68 hours. Plus, it has a stopwatch function for minutes and seconds, as well as a convenient flyback function. No wonder it's a favorite among watch enthusiasts.
