How to Authenticate Patek Philippe Twenty-4
The Patek Philippe Twenty-4 is frequently counterfeited. Here is how to verify authenticity:
Hallmark: 18K gold stamp must be present and professionally executed. Thin plating on fakes wears quickly.
Stones: Authentic Twenty-4 uses quality stones with precise setting. Check for gaps in the prong setting.
Weight: Authentic pieces have substantial feel. Unusually light weight suggests base metal.
