Authentication Notes
Bezel

Eight hexagonal screws
The octagonal bezel is secured by eight white-gold hexagonal screws whose slots are aligned; misaligned or Phillips-head screws are incorrect.
Bracelet
Medium
Integrated, hand-finished bracelet
The integrated bracelet has alternating polished/brushed links with hand-applied bevels; soft edges or a removable end-link are wrong.
Dial
HighHigh confidence
Tapisserie dial pattern
Genuine Royal Oak dials use a precisely machined 'Tapisserie' guilloché (Petite on the Jumbo, Grande on 41mm). Shallow, uneven or printed 'waffle' patterns are a strong counterfeit indicator.
