The Longines Telemeter Chronograph L2.780.4.18.2 is a timepiece inspired by a 1933 Longines chronograph. It features a 41 mm stainless steel case housing the Longines caliber L688, a self-winding mechanical movement with a column-wheel chronograph mechanism. The white lacquered dial displays black Arabic numerals, a red telemeter scale, and a spiral tachymeter scale. Blued steel Breguet hands indicate hours and minutes. The watch includes a date aperture at 4:30, a small seconds sub-dial at 9 o'clock, a 30-minute counter at 3 o'clock, and a 12-hour counter at 6 o'clock. It is fitted with a black alligator strap.
