Longines Dress Watch Value Guide

This mid-century Longines dress watch represents the pinnacle of Swiss industrial watchmaking from the 1955-1965 era. Renowned for its minimalist elegance and mechanical reliability, this model often houses prestigious movements like the Calibre 23Z or 19A, making it a cornerstone for vintage horology collectors.

What affects the value of Longines Dress Watch?

• The functional condition and service history of the Calibre 23Z or 19A mechanical movement.
• The physical state of the 10k gold-filled finish, specifically looking for 'brassing' or wear-through on the edges.
• The integrity of the integrated mesh bracelet, as these are difficult to repair or replace without losing original aesthetics.
• Dial originality, with unrestored 'patina' dials often commanding higher prices than poorly refinished examples.

How to Identify Longines Dress Watch?

• Check for the Longines winged hourglass logo on the dial and the internal movement.
• Verify the 10k gold-filled hallmark on the interior or exterior of the steel case back.
• Inspect the integrated mesh bracelet for seamless attachment to the case, characteristic of 1960s styling.
• Confirm the presence of an authentic acrylic crystal and a period-correct Swiss mechanical movement.
