simple answer is hold out for the 232.
if cali, 249 over 448 (i just can't deal with the "vintage" and "california" engravings on the 448, plus, the 448 is thicker).
as for newer models, note that with the 424, the original date version has been replaced very recently with a non-date 424. for the SLC, i like the 425's gold coloring over the 449, but, then, i'm not a "DNA purist".
re: the 514, the radiomir 1940s case is nice, but, i'm not a fan of the 514's faux patina. therefore, i prefer the 532 over the 514 for 47mm 1940s, since i think the faux patina of the 532 looks okay with the DLC and asso strap.
re: 504, it has a good design and the composite is a nice brown, but, OP has discontinued once again its composites. makes you wonder if OP ever got their composites right or not.
