To spot a genuine 2002 Rolex Datejust, start by examining the dial and case for precise craftsmanship—Rolex is known for flawless detailing. Check the serial and model numbers engraved between the lugs, which should match official records for a 2002 Rolex (https://scottreddickwatches.com/product/classic-rolex-watch-with-blue-dial/). The movement inside should be smooth, with no ticking sound, reflecting authentic Swiss engineering. Lastly, inspect the bracelet and clasp for solid construction and the iconic Rolex crown logo for authenticity.
I see it's been a while since you've posted, but I totally agree with your points. When I bought my first Rolex, I spent hours checking the dial, case, and serial numbers.
Saw something similar once when checking out watches online. Found https://www.reveriewatches.net/ and was surprised how good some replica watches looked, especially close-up.
