Did i buy a genuine rolex??

[sm1970]

Hello all,

Could someone help me please..
I recently bought a Submariner watch for my hubby and i wanted some help identifying its authenticity.
The watch has the following..

[*]Hologran back sticker with the model number 16233.[*]On the inside of the watch face rim it has the number engraved F872143 and ROLEX repeated after it.[*]It has the Rolex crown hologram directly above the 6 o'cklock on the glass.
[*]When i had the band opened there is no serial number between the lugs but i have read that in the case of Oysterquartz models, [*]the Case Reference Number is located on the back side of the case lugs and my end lug does have embossed a small rolex crown followed by CL 72200 then another rolex crown.
[*]Also, it has the black o ring on the wind up.


I hope this is enough information for everyone and i hope someone can help.

Thank you all so much
