Rare Omega Vintage Watch: Identification Guide

Key Points from the Discussion

• The presented Omega is a rare reference 2852, particularly desirable when featuring rose gold hands and markers. Even rarer are black guilloché dials with yellow gold accents, and the absolute rarest are white gold cases with matching white gold furniture, available in both 18kt and 14kt.
• The original owner of a similar rare Constellation, found in a drawer, had the crown changed for a serrated Omega crown for easier winding, indicating that non-original crowns can sometimes be a practical modification rather than a sign of lesser value.
• While many Omega Chronomètre versions exist, only a fraction feature the highly sought-after 'Pie Pan Dial.' For reference 2852 specifically, it's estimated that perhaps one-fifth at most were produced with a Pie Pan dial.
• The combination of rose gold hands and markers on references 2648, 2652, and 2852 is exceptionally rare, with only a handful observed over many years.
