Longines Ultra-Chron Value Guide

Introduced in 1967, the Longines Ultra-Chron was a pioneer in high-frequency horology, operating at a remarkable 36,000 vibrations per hour for superior accuracy. These 1960s Swiss-made timepieces are highly collectible for their technical innovation and robust automatic movements housed in classic 10K gold-filled cases.

What affects the value of Longines Ultra-Chron?

• Mechanical health and timing accuracy of the high-frequency caliber, as these movements require specialized maintenance.
• The condition of the 10K gold-filled exterior, specifically checking for 'brassing' or wear-through on high-friction areas like the lugs.
• Originality of the dial and hands, as refinished dials significantly reduce the collectible value for purists.
• The presence of the original signed Longines crown and any period-correct bracelets or buckles.

How to Identify Longines Ultra-Chron?

• Look for the Ultra-Chron branding on the dial, typically accompanied by a distinctive four-pronged wave or lightning bolt logo.
• Verify the high-beat movement by observing the exceptionally smooth sweep of the second hand, which is much more fluid than standard vintage watches.
• Check the case back and lugs for 10K gold-filled or stainless steel hallmarks consistent with Longines' 1960s manufacturing standards.
• Confirm the presence of a genuine Longines automatic movement designed to operate at the signature 36,000 vph frequency.
