16750 Question

[cowboy music]

Hi all,

First post. I'm new to Rolex, just bought my first one a couple months ago from one of the RPM dealers. It's a 1982 16750, 7.3 mil. SN. Honestly, I thought I did a lot of research on these watches prior to purchase, but I have since found this forum and been blown away by all of the information here.

From what I can tell, the watch has a MK 2 dial. The hands seem to match well. The bracelet is a 93150, which I understand was an option for the watch at the time it was originally purchased.

A couple questions in particular:

Is the insert correct? I believe it should be a red back one. I don't know how to get it off, and I'm afraid I'd scratch it to death if I tried.

Also, are the hands correct? They all seem to match, color-wise, to each other and to the dial.

On the date wheel, the 6 is not open. Does that mean it is a replacement date wheel?

Honestly, I tried to practice the "buy the seller" mantra, and in doing so, I guess I figured everything would be correct, but after reading so much here, I'm not so sure.

I appreciate everyone's willingness to share so much knowledge. Thanks.
