I'm picking up my "one" Rolex soon. Previously I've owned -Various datejusts -Milgauss -Various submariners ranging from vintage to more modern, but nothing newer than 2010 or so I have come to the conclusion that I definitely want "a" sporty GMT/sub back...
Matt brownish dial. 40mm. No cyclops. Extruding crystal like Subs of old. Superb diving credentials. Superb bracelet technically. Very rare compared to anything else modern
Especially on a jubilee it is so chic. No date sub is a classic yes, but a tad too dull compared to the batgirl. You already have your beater divers, instead of a tool watch, I’d go with the bling option.
I know your stated preference is for a no date. But if you can live with it on the Batgirl, I thought I'd throw these out there for consideration. Both have a pop of color. And IMHO, the Yachtmaster with the blue dial is very underrated/underappreciated.
