The Longines Twenty-Four Hours
Single Push-Piece Chronograph

Longines has been based in the market town of St. Imier since it was founded in 1832. As a tribute to its precious heritage, the Swiss watch producer takes its inspiration from the models in its museum to design watches that reflect its vast know-how. The latest addition to the Heritage collection is The Longines Twenty-Four Hours Single Push-Piece Chronograph. Housing an exclusive calibre, this single push-piece chronograph is a re-issue of an earlier pilot's watch and displays the time on a 24-hour scale.
