North Jersey 16233 authenticity check

[Reddit]

Recently bought a 16233 vintage for around market price from a known quantity but I want to have someone else confirm authenticity. Recently had an issue of a watch with mixed genuine and non-genuine parts find its way into our Rolex group and wanted to avoid the same situation.

Anyone know where I can find a someone to confirm authenticity? Not going to looking for papers, just confirming what's under the hood is correct. Got a service card with recent service date in march 2020. Pictures attached. Looking for shop in North Jersey by the GW bridge.
