Seeking advice: Serti 16613 - real or fake dial?

[nonkool]

Hello all - this is my first post here at TRF, so please be kind.

I am also seeking my first Rolex, having become interested in the brand at the worst time - when things seemed to be at the peak.

I have been trawling various greys since, and a Serti Sub 16613 caught my eye. Upon comparing its dial to other similar watches, I am unsure if the watch/dial is real or fake. The grey seems reputable, with a retail store, and mentions the watch comes with box and papers.

Could the resident experts here at TRF please help advise? Much appreciated!
