The Longines Column-Wheel Chronograph is designed with traditional, elegant lines evoking the watches that built the brand's 20th-century reputation. Its self-winding L688.2 movement, featuring 27 jewels, measures 30 mm in diameter and 7.90 mm in height, and is visible via the transparent caseback; the column wheel guides the chronograph functions. This 39 mm 18-carat rose-gold case encloses a silvered dial with a rose Arabic '12' and eight applied rose hour markers, showing hours, minutes, small seconds at 9, date, and chronograph features: sweep seconds, 30-minute counter at 3, and 12-hour counter at 6, on a dark brown alligator strap, water-resistant to 3 bar.
