Longines started manufacturing timing equipment in 1878 with the launch of a simple 20 ligne column-wheel chronograph, reference number 20H. Over the years, many other Longines chronograph calibers have incorporated a column-wheel mechanism. The new Longines Column-Wheel Chronograph continues this horological heritage into the 21st century. This Longines houses a new caliber developed by ETA for Longines and other brands within the Swatch Group. Fitted with 27 jewels, the L.688.2 movement is a self-winding caliber with a diameter of 30 mm and a height of 7.90 mm. The blued steel column wheel controls the chronograph functions (start, stop, return to zero).
The new movement is housed in a classic case from the Heritage collection. The 40mm stainless steel case offers a transparent case back. The gold-plated Dauphine-style hands are mounted above a silvered dial featuring gold-plated applied hour symbols, a small seconds at 9 o’clock, a 30-minute continuous action counter at 3 o’clock and a 12-hour continuous action counter at 6 o’clock. You may view the technical specifications below.
