I have a 2 liner
They are all the same prices relatively (14060 and 14060M)
Things to consider:
Tritium vs Superluminova (I wanted lume), you already cracked the code and found out that T swiss <25 T means tritium and swiss/swiss made means superluminova.
One thing you may not have noticed is that there are dial logo variations. If you google 14060M you will find this monstrosity:
The coronet logo is shorter on the outside flanges, it's genuine but I do not like.
Lug holes or no holes case? (I like lug holes, last of the "true sports subs" and you can get visual confirmation that your spring bars are seated)
2 or 4 line dial? I like 2 because you can only get it on the submariner (all sub dates are chronometers) and it's symmetrical with the top two rows, and the newer subs are all 4 line so it's unique.
4 line dial: some/maybe all come with engraved rehaut which I could take or leave, but no 2 liner has engraved rehaut so I do not have it.
Overall: pick one that is in GREAT condition, unpolished if possible but you never really know, look for those bevels...
Pick one with the specs that you like. For me it was two liner with lume and lug holes and I love it. You are going to end up spending well over $6,000 so you should take your time figuring out which configuration you're after and hunt it out. They made lots of these so I wouldn't worry about lack of supply. I got mine in 2014 and I thought what I got it for was steep. Now it's borderline crazy. However they do hold value insanely well and I adore the watch. Message me if I can help any more.
