With counterfeit watches becoming increasingly sophisticated, knowing how to authenticate a Rolex is essential before making a purchase. At Open Wrist, every timepiece undergoes our rigorous multi-point authentication process.
The Weight Test
Genuine Rolex watches use 904L stainless steel and precious metals. A real Submariner weighs approximately 155 grams. Counterfeits often feel lighter due to inferior materials.
The Movement
Rolex uses in-house calibers with a smooth sweeping second hand at 28,800 beats per hour. Fakes often have a stuttering tick or inconsistent sweep.
The Cyclops Lens
The date magnification lens on genuine Rolex watches magnifies 2.5x. Counterfeits typically show less magnification, around 1.5x.
Serial & Model Numbers
Authentic Rolex watches have deeply engraved serial numbers between the lugs at 6 o'clock. Modern references (post-2005) also feature a laser-etched crown on the crystal at 6 o'clock.
The Rehaut
Since 2004, Rolex engraves "ROLEX ROLEX ROLEX" around the inner bezel ring (rehaut). The serial number also appears at 6 o'clock on the rehaut.
