In the case of the Longines Column-Wheel Chronograph, priority has been given to classical, refined beauty. The 18 carat rose gold case houses a L688.2 calibre, a self-winding movement 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. The 39 mm diameter case surrounds a silvered dial features 13 rose hour symbols. It displays the hours and minutes, with a small seconds at 9 o’clock, the date and 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).
