Press release
The Longines Column-Wheel Single Push-Piece Chronograph 180th Anniversary Limited Edition is closely based on the first wrist chronograph, manufactured by Longines in 1913 and fitted with calibre 13.33Z. The new model uses calibre L788, a column-wheel chronograph movement developed exclusively for Longines which enables the wearer to activate the various chronograph functions – go, stop and reset to zero – by simply pressing on the single push-piece integrated into the crown. With its sleek lines and white dial featuring a bright red “12”, this model recalls the Agassiz dial of the original version, while the moving lugs are part of Longines' prestigious heritage. This model is available in rose gold and has been manufactured in a limited series of 180 numbered pieces.
