Omega Vintage Watch: Collector's Guide

Key Points from the Discussion

• The dial appears to have been refurbished, as it is missing the 'officially certified' text below 'chronometer,' which is a key indicator of originality for this reference.
• The movement's caliber number is critical for authenticity; if it's a caliber 564, it's likely incorrect for the case, whereas a 561 would be original. Dennison-cased Omegas, common in the UK, pose a challenge as Omega Bienne cannot provide extracts for them.
• Caliber 564 features a quick-set date function, unlike calibers 561 and 504, which helps in identifying the correct movement for a specific reference.
• There was an overlap in production, with caliber 561 examples appearing as late as 1960, indicating that some later Dennison Constellations could legitimately house this movement.
• The advertisement shown might depict a reference 168.002, which typically housed a caliber 561, rather than a 16955, which had a caliber 28 SC or 504 and a twelve-sided crown.
• Despite potential authenticity concerns, if a watch resonates with the collector and is financially viable, the emotional connection can outweigh strict originality for personal enjoyment.
