Rolex Submariner

A convincing "super clone" Rolex Submariner now costs $500–1,000 to produce and can fool casual observers. Real tells: the seconds hand sweeps at 8 beats per second (not a quartz tick); the Cyclops lens magnifies the date 2.5×; the crown engraving on the crystal is invisible without magnification. The defining test: a genuine Rolex movement is visible through the caseback and sounds and feels entirely different from a fake.
