Thoughts on this Rolex 16750

Hey guys

After some years of having new Rolex' I've been thinking of moving more into vintage. It's a whole new world with lots of different aspects to watch out for when buying.

So, what do you guys think of this 1983 Rolex 16750 (SN 7,6) - case, dial, insert?


Much appreciated

Case looks good. Service dial and hands?

Dial looks original for the case number. I would venture to say the insert and hands have been replaced at some point. Check the hands and see if they glow in the dark. If they don't, they are probably later replacement tritium hands or possibly original. If they glow substantially, they are luminova replacements.


The bracelet should be a 78360 based on your photo. Clasp code should be G or H. The end links with the spring bar cut-outs are not correct and are later replacement ones if they are genuine Rolex.

Service dial???? There were never any matte service dials.

Service dials for the 16750 had a glossy black finish with gold surround markers.

The dial then looks remarkably pristine and white for something that is 33 years old.
Does a 1675 dial fit the 16750?

No . . . a 1675 dial does not fit a 16750. The 1675 dial feet are located in a different position than found on the 16750s.

White markers is not a method used to determine if a dial is a service dial.

Yet you venture to say that the hands may be replacements due to the condition/colour correct?

Not really. I base it on my experience...40 plus years of collecting. He asked for an opinion and I gave mine. It seems to differ from yours, sorry.

Have a great evening.

exador,

With all due respect, Springer has forgotten more about GMT-Masters than most of us will ever know, collectively. As I have opined previously, he is the undisputed source. I continue to learn from his posts. And, no, this is not a paid commercial, we don't know each other.

Hi and thanks for the comments. I'm not having a go at Springer and defer to his experience. However I own several tritium dialled watches of similar vintage (including a 16750) and all have yellowed plots/hands, so you can understand why I would query this watch.

A considered explanation of why this particular dial and hands may not have aged would be of benefit to the whole community.

Cheers

Please read my post again. I also said they are possibly original - referring to the hands might possibly be original. It is hard to make a 100% complete judgement based on a couple photos.

Some vintage watches turn an eggshell color, some become light yellow, some dark yellow and some remain white. Since you are new to vintage, spend some time here and do some research on patina. There are many threads in the vintage section discussing patina, why it occurs and how it occurs. In short, many vintage watches that are worn on a regular basis, I'm talking years to decades, can change in color from yellow to white due to light and UV rays. I wore a GMT 16750 for over a decade and the dial and hands changed from light yellow to white over time. There are other reasons as well, but I'm not a scientist.

I think it's the oil used to service the movements. It must be in the air pocket of the watch and the lume absorbs it. Just my theory

What's the price? That's a very handsome looking 16750.


I blame it on the autoconnect.

Thank you for the feedback.

So to sum things up:
Case looks good?
Dial and hands are period correct to the watch and original if they don't glow?
Is the insert af servicepart or period correct to the watch as well?

The bracelet is a 78360 but with 501B endlinks - these should be 580 if I'm not mistaken.
