Advices on new Watch

[Vinnywatchpassion]

Goodmorning everyone, i m Happy and thankful to join this Amazing forum community, i m a guy under 30 ( still for One year:D) with a big passion for watches, having in collection a datejust 126300 blue dial Oyster bracelet and a Rolex Explorer tt anniversary 124273. Trying to add One more piece in my collection, what would you go for a 124300 , 126710grnr, 126622 rhodium or 124060? I like all of them, but i have to decide wich will be next in collection, and i really Need your precious advice;
124300: Always liked the Classic Oyster Perpetual in this new reference, love the green dial and price more affordable also if for this model i should go grey with a premium of 1500€
126710grnr: One of my Dream Watch Is the GMT especially with Oyster bracelet, the ad, when i tried on this reference ( wich i like the most compering to others gmts) told me Is not impossible but i have keep visiting the store to see if they Will get One for me in future (this ad i dont have history because i had to move back to my country and my watches i bought at another ad far from me right now), go grey Is not an option for this model, too big premium for me. This Watch It would be a complication that i dont have (btw my 124273 has same movement as the 124300)
126622: looking at the ehstetics Is beautiful, nice Lines and fit perfect on the wrist because It Is less thicker than the GMT but has same movement as the datejust
124060: an icon, a diver that i dont have, same movement as my 124273 but with 300 m waterproof , i like as well this model and missing It but probably have some more preference and the others 3 models

My big question Is It deserve to wait and see if i can get a GMT that i like from the ad or go grey and take the op green or asking for a yacht master or 124060?
Which Will be the best add to have an equilibrium in my collection?
Thanks in Advance for the future advices
