In the case of the Longines Column-Wheel Chronograph, priority has been given to classical, refined beauty. With its 27 jewels, the L688.2 movement is a self-winding calibre with a diameter of 30 mm and a height of 7.90 mm that can be admired through the transparent case back. The column wheel that forms part of the movement serves to steer the functions of the chronograph mechanism. This model has a stainless steel, 39 mm diameter case that surrounds a silvered dial with 13 hour symbols. It displays the hours and minutes with a small seconds at 9 o’clock, as well as the date plus of course the chronograph functions: centre seconds sweep, 30-minute counter at 3 o’clock and 12-hour counter at 6 o’clock. This model is fitted on a dark brown alligator strap. Water-resistant to 3 bar (30 metres).
