Rolex Submariner 1680 advice

[Treborian]

Advice needed.

I’m on a hunt for a 1680 from my birthyear 1976 and found this one. It looks good but I’m having second thoughts about the lume and a few other things. The lume seems inconsistent and uneven. It’s my first vintage piece (I already have a Explorer and Explorer II) so I’m no expert in vintage by any means.
Except from the lume, the case and dial looks OK but the insert looks strange with a square ”4”. It doesn’t look like a MK1-3 or even a service insert from that era. The watch was sold in the US in the end of the 70’s.

Please chime in with comments and advice if possible.

Thanks

The insert, I believe, is a later 1980s service insert. What’s the serial number? 1976s were, largely, service cases. The uneven lume, if it’s a point of apprehension or irksome to you now, chances are it’s gonna nag at you every time you look at the watch. I’ve had Subs and a GMT in the past w inconsistent lume and I never got over it...much as I tried. What’s worse is that when it came time to sell them, it made it all the more difficult
Take your time, pay a little more than you planned on, and get a watch you’re entirely happy with. It’s not worth the headache getting one with multiple issues.

Thanks a lot for the feedback an comments!

I don’t have the serial nr and regarding the lume, you have really valid points. Thanks!

The lume appears puffier and too discolored compared to good examples I’ve owned and handled.
