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.

I would say that this is a nicely overhauled GMT Master.

Great watch! Wear it in good health!

I believe the date wheel should be open 6 and 9, if you want to be period correct.

I'm not an expert but I think your watch looks great. The model and vintage are the same as mine so I have included a photo for comparison.

Agreed! Get it on your wrist!

Thanks everyone! I appreciate you taking the time to comment. I really do like the watch, and I've been wearing it for a while now.

The "open 6" thread that was started a couple days ago got me worried, however, since my 6 is not open. I'm curious why the date wheel would ever need to be changed? How would it get messed up?

The red/blue insert is correct for this model. The red/black version was introduced in a later model (16760)

He's talking about the color of the "back" of the insert.

Yes. I misread that as red black rather than "red back"

Very nice!

[Stuntpilot]

Nice. I wish the bubble would burst on these.

Don't let the date wheel fanatics wreck your day. Is is minuscule in the scheme of things. This date wheel fixation started out as a school-boy fixation...such as "my watch is ore correct than yours." I've never seen one of these date wheel aficionados ever mention or worry at all about other gears or wheels in their movement not being original.

It gets changed because it is a very thin piece of metal and there are probably 70 or 80 cogs on it that turn the wheel. They get worn out after a while and since it is a very inexpensive part, it gets changed during servicing.

The insert for the serial range being discussed should have a red back if you need it to be correct.

Maybe you should start a closed "6" thread. I'd help you with a post!

On that model there are 31 "cogs" or teeth (one for each day of the month)
Each one is solicited once a month...

So, it should be called the "marriage" wheel or the "bachelor" wheel?

[Tools]

The tiny fingers that stick out on the inside of the datewheel for the GMT are "slapped" once a day, every day, by the mechanism that gives you the instant date change.

That daily slapping takes it's toll and damage, bend, or break a finger frequently.

There is no shame in replacing broken or damaged movement parts...

Can you tell from the picture whether this watch has the correct insert? Or do I need to remove it?

That's great information. Thanks!

And to everyone, thanks again. Like I mentioned previously, I love the watch and have been very happy wearing it. It's my first one, so I appreciate all of the positive feedback.

Love the patina!
