16600 flat 4 Genuine or NOT?

[Thrasher36]

I got this allegedly genuine flat 4 16600 Sea Dweller insert recently from a reputable seller on the Bay with 11K sales and all positive feedback for the year. He sells mostly Rolex and other high end watch parts.
It just looks to good to be true. The price was fair and comparable to a genuine 16610 insert, you very rarely see these and in such good condition thats why I ask.






His description:
1990 Rolex 93160 Sea Dweller 16600 16800 16808 16613 Model Watch Bezel Insert

Rolex Sea Dweller Bezel is in Good condition 36.45mm OD and 29.9 ID

It has very minor scratches. Don't miss out!

This is a genuine Rolex part so you can be assured of it is of the highest quality.
