Blued Steel: Longines Column-Wheel Chronograph
The Column-Wheel Chronograph was a important introduction for Longines at Baselworld this year. It features the new L688.2 calibre movement, developed in-house (by ETA). The new movement is housed in a traditional 40 mm stainless case. It features a small seconds subdial (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). A date indicator sits in between the 4 and 5 o'clock indexes. The dial is silvered with gold-plated Dauphine-style hands and gold-plated hour markers.
The most striking feature is a blued steel column-wheel. Instead of a cam and lever, a column-wheel controls chronograph functions (start, stop, reset). The caseback is see-through, so you can easily admire the movement and its unique blued column wheel.
