Hallmarks
HighHigh confidence
Patek Philippe Seal
Movements since 2009 carry the Patek Philippe Seal (earlier pieces the Geneva Seal). The stamp, plus the reference and case numbers engraved between the lugs, must be crisp and internally consistent.
Movement
HighHigh confidence
Hand-finished movement
Expect Geneva striping, chamfered bridges and a gold rotor visible through the sapphire back; rough finishing or an ETA-style movement is disqualifying.
