448 for me as well. Blue hands were a must for me.
Then the price reduction earlier this year made it a no brainer. Even though all four models (424,425,448,449) are very well replicated, they are very similar as well.
Love my 448, price reduction makes it a no brainier. I do like the fact that the 424 and 425 are sapphire vs plexi but that comes with a substantial cost premium. Wanted to add another SLC dial to my collection as I have a fantasy watch radiomir with that dial and was debating the 425 vs 449....after weighing all the pros/cons am going with a 373 from TS.
