Is this a fake watch - Daytona

[santoshlv426]

I saw an advert for a "Daytona" on FB. The pictures indicate it's a genuine (to me at least) Daytona being sold for a ridiculous sum of < $200 with the seller stating he needs the money.

It's complete, watch, box, bracelet tag - really everything as you'd expect with a Rolex.

Upon requesting a picture of the cards, the rear of the card is blank - no stamp or serial number.

It's new. The watch still has the plastic glass protector and cloth.

All seems perfect (I can't tell a fake from a real pictures or not), except for the blank warranty card.

What could be the deal here ? what would it mean for Rolex or any luxury watch to find itself in circulation without a stamped warranty card reflecting it's serial number

If someone had to aquire it and it's genuine, would Rolex even support it not knowing who sold it ?
