Datejust 116200 Bracelet 72200 - Laser etched all clasps?

[Icantaffordrolex]

Hello, do all 72200 bracelets have the number laser etched on the inside clasp? The first photo is from a watch listed on eBay without the 72200 code etched on the inside of the clasp. The second photo is of another 72200 bracelet with the code etched.

Also, is it weird that, on the first bracelet, there is a 4 digit serial number (PJ01) etched above where the 72200 code should be? On the second bracelet, there is a 3 digit serial number (OP1) etched.

I’m concerned that the first bracelet is a fake.
