How Is the Authentic Gibeon Meteorite Widmanstatten Dial Crafted on Rolex Ref. 126518LN?
The Rolex Cosmograph Daytona Reference 126518LN features a genuine extraterrestrial Gibeon iron-nickel meteorite dial displaying an acid-etched Widmanstatten crystalline lattice pattern inside a 40.0 mm x 11.9 mm 18K Yellow Gold Au750 case weighing 160.4g, because octahedral nickel-iron crystals cool over millions of years in space to form unique non-repeating metallic striations.
