Help I.D My First Rolex

[tunnelno5]

Hello,

My father handed me down a Rolex Datejust as a family heirloom. I am greatly excited as this watch has immense, sentimental value.

My father purchased the watch from Rolex in the States and currently has the paperwork associated with the watch, however, I thought it wouldn't hurt to ask the members of this forums for specifics (model, specs) and any details on servicing my Datejust.

The watch hasn't been serviced since purchased, however, the watch runs extremely well except for cosmetic scratches and a chip on the crystal. I am planning on servicing the watch at an authorized Rolex Service Center, but am wary of servicing the watch anywhere other than a Rolex service center in the States. I wonder if my skepticism servicing the watch at a Rolex Service Center in other countries is valid.

Excuse the long read, let's move on to some photos! :)
