Is this Sea Dweller authentic ?

[Borg1981]

Hi Everyone,

Very first post here, spent some time
this afternoon looking thru the forum - lots
of great info. My brother sent me some pics of a Sea Dweller
someone is looking to sell. I really don't know very much about
this model to know if it's a copy or authentic Rolex ?

Was hoping one of you that own or know what to look for can verify if this
is a real Sea Dweller as the seller lives 3 hrs away and the nearest authorized dealer is in Toronto...Apologies for the picture quality as this is what the seller sent him. He mentioned more pics are forthcoming from him.


Thanks in advance for any feedback on the watch's authenticity.
