The cap comes off in a standard anti-clockwise direction. If it will not disassemble following the instructions in my tutorial, it may be internally rusted together. Try soaking the crown in penetrating oil, then try again.
Now here is a Panerai that, if they ever made it available in a non-super-sized size (less than 40mm), might get me to rejoin the fold -- Luminor Submersible 1950 3 Days Automatic Bronzo
I am usually 1 of the 1st to suggest that, with vintage Rolex, there are always exceptions to the rules. This may very well be 1 of them. But since I have never seen 1 in any of the Rolex bibles or posted by 1 of senior members of VRF/TZ, I would need to see some provenance before I could accept a gold, CG-less 1565-powered (this has to be assumed, since no pics of the movement were posted) 1675 with simple baton hands as fact.
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.
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.
