Longines Tre Tacche

About this reference

The Longines reference 4974 was produced during the 1940s and is no longer in production. Collectors prioritize this reference for its "Tre Tacche" case design, characterized by three distinct notches on the screw-down caseback which enhanced water resistance. The 37.5mm stainless steel case is considered oversized for its era, housing the manual-wind caliber 12.68Z. Dial configurations vary, but examples featuring sector layouts or radium luminous numerals command the highest interest due to their military-inspired aesthetic and rarity. On the secondary market, prices typically range from $10,000 to $25,000 depending on original condition and dial rarity. A notable production detail is the stepped bezel construction, which distinguishes it from smaller contemporary models. In 2023, well-preserved examples with original finishes have appeared at major auction houses, confirming the reference's status as a significant mid-century steel sport watch.
