As part of the Longines Heritage Collection, The Longines Column-Wheel Single Push-Piece Chronograph models recall the very first chronograph wristwatches created by the brand in 1933. These timepieces housed the 13.33z calibre, the first chronograph movement made by Longines to equip wristwatches.
The Longines Column-Wheel Single Push-Piece Chronograph model houses the L788 calibre, a monopusher movement developed by ETA exclusively for Longines and which, like its illustrious predecessor, is equipped with a column-wheel and measures 13¼ lines. All the chronograph functions can be controlled by simply pressing the single push-piece.
The Longines Column-Wheel Single Push-Piece Chronograph comes in three versions, all with a 40 mm diameter. Two versions, one in steel and one in rose gold, feature Arabic numerals, and a third version, also available in steel, displays Roman numerals. The single push-piece, inserted into the fluted crown, recalls the original timepieces. The white dials are adorned with painted black numerals and a red "12", in a direct reference to the dials of the period. They are completed by two counters, at 3 and 9 o'clock, together with a date aperture at 6 o'clock and blued hands.
The cases are a particularly interesting feature of these timepieces. Two of the models have a well-rounded case, available in steel and in rose gold. Taking its inspiration from an historic timepiece, the third model in steel is fitted with moving lugs. This version has a thicker case with a more angular profile. On all three versions, the movement’s blue column wheel can be admired through the transparent sapphire crystal case back. All models of The Longines Column-Wheel Single Push-Piece Chronograph are fitted with a brown alligator strap.
