Hello guys! Initially I was inclined to buy the Seamaster 300 pre-2018 model (the one with the dial without wavers) because of the slightly smaller size. However, it seems that it is difficult to find, I read that the best factories were MKF/MKS, but it would seem to be no longer found. So I am heading towards the new model and reading the famous comparison found on the forumit woud seem ZF to be the best. I'm a little afraid though about the problems I've heard about the noisy rotor as I can't solve it myself. I had a problem with my Planet Ocean purchased by Ryan as it just got stuck, but I eventually bought an original ETA 2824 and a watchmaker near me replaced it. Do you think there are worrying problems in ventruring with ZF?
