Does this watch have any provenance?

Antiquorum is good, but sometimes fallible. So, with something like this, I would feel alot better if I could see the model number (1675) between the lugs (on an authenticated watch). I searched VRF & TZ, but, like everything in my archives, all the gold 1675s have CGs.

I have never seen/heard of a ncg 1675. What movement powers an ncg 1675?

6542s came with coin-edge bezels (so they do not cover the crown like the bezel in the OP's pic does) That bezel may be gen, but it is not 'original' to a '42.

585s were spec for the (solid link) 93150 bracelet, but 580s (which are what I have on my 93150) fit nearly as well. 285s or 385s were spec for the earlier (folded link) 9315 bracelet (I have 385s on my 9315).

The (modern) gen 116710LN has a ceramic bezel insert (the part inside the bezel containing the numbers). Most newbies are not aware that the insert & bezel are separate parts. Ceramic is a modern material & has only been available on Rolex watches for the past few years (no vintage Rolexes have ceramic anything).

Although the CHS version tends to have more problems due to the relocation gearing's poor design, you can improve your long-term chances by not using the GMT function. My CHS came from the initial shipment (3 years ago) & I have never had any problems with it. To the best of my knowledge, the only part that is ceramic on these is the hyperbole that accompanies them.

I am not a PVD (or similar coatings) fan, but, with that strap, it does not look half bad. Ending the work week wearing 1 of my Newmans (3rd from left)

Impossible to tell without good, clear macro pics, but it does not look to be a 100% original (Swiss-made Rolex) 6542.

Wow!

The only genuine (Rolex) part is the movement. Everything else is clearly aftermarket. So either he's spinning the story about the 'very good rolex watch repair shop' or they are not very good.

Super Super, LHOOQ.

Search the dealer listings. I am pretty sure some of them offer similar GMTs (& Subs).

Based on current values, the 16520 is likely going to be the better investment over time. Generally, if a given model is collectible, older is better. In this case, the 16520 is also a bit less blingy, which, in today's market at least, also tips things in its favor.

I've never done anything to it, so it should be.

Took the words out of my mouth.

Sad to think how bright the future looked back then (1960s). It seemed like America's glory would never end.

I got it (used) in 1975, so it is late 60s/early 70s. Unfortunately, it does not go to 11.

In theory, the internal dimensions of DW 62xx Daytona cases for 7750s differ from those made for V72s (the external dimensions are the same), but the variations may be due more to the lack of QC & overall case-to-case variability than anything else. Either movement can be made to fit a given DW case with a bit of dremeling (which is often required anyway).

I believe it is just the 160x series of DJs, powered by 156x/157x movements, that have pie-pan dials. Earlier versions, powered by either 1036 or A.295/296 movements, & later versions, powered by 3035 movements, have flat dials.
