Ultra-Chron 43mm Mens Watch

This 43mm timepiece draws inspiration from Longines' 1968 Ultra-Chron Diver, the first dive watch to employ a high-frequency movement. The current iteration maintains the professional diving aesthetics of its predecessor whilst incorporating modern refinements. The watch features a chronometer-certified in-house Longines calibre fitted with a silicon balance spring for improved accuracy and magnetic field resistance. The dial presents classic dive watch legibility with luminous hour markers and hands, whilst the case houses the movement at the centre of a robust sports watch design. Water resistance meets contemporary diving standards, making the piece suitable for serious underwater exploration alongside everyday wear.
