It's a bad fake. A good fake would need a look at the movement inside for comparison, but there are a number of external features on this one that give it away, making a look inside unnecessary.
- Plastic wrap on the bracelet is a dead giveaway that it was manufactured in some no-name counterfeiting factory, not Rolex.
- Cyclops over the date is not 2.5x, though it might be about 2x.
- The text and the alignment of the indices and the markers on the right half of the dial are not precise/perfect (note that the indices don't line up exactly down the middle with the markers for 10, 20, and 25); Rolex would not sell a watch with such noticeable imperfections. The "Swiss Made" marking at 6 o'clock is also obviously asymmetric, while a legitimate Rolex would have that text sized/spaced out such that the two words would appear to take up the same amount of space.
