Then new Longines Ultra-Chron, ticking at 10 beats a second. The new high-frequency movement guarantees higher precision and profits from Longines’ rich heritage of producing high-beat movements for over 100 years. Inspired by the original Longines Ultra-Chron Diver of 1968, the new model reflects the iconic design codes of its ancestor and is highly resistant to shocks, scratches and water pressure.
