Is this a fake??

[Sherio]

Flying from Mumbai airport today and spotted this piece in their “used” Rolex display, the sales guy told me it was polished and serviced with a 1 year warranty offered, they also said it was only customized with a white gold bezel set with diamonds.
The problem is I’ve searched online extensively for an exact similar one ( ice blue dial with Roman numerals on oyster, excluding the diamonds since they are customized ) and the only time I found any thing similar it was titled as a “replica” !!
I can’t believe that an authorized dealer in an international airport with be selling fakes, but it’s either this or he has a Rolex that so rare to the extent that I can’t find a similar one online!
His asking price was $5700 and the even had 2 identical ones on display.
Appreciate your feed back.
