Hey everybody, I just purchased a Speedmaster Day/Date ref. 3523.80. It's my first speedmaster, and though it's just an automatic and not a chronometer, I noticed that when I start the large seconds chronograph it's not a really fine, fluid, automatic ticking like my SMP Chrono. It's mostly fine, but sometimes has little tiny jumps and fraction of a second pauses, especially when crossing the other hands, though it still seems to time the minutes just fine. All the other hands, including the small seconds, run fine and fluid. I've never owned a speedmaster before, let alone a day/date, so is this normal? Should I have it checked out? I don't like to think there's something catching in the movement in there or something. I was thinking though that since it's not a chronometer and since the movement's relatively complicated for an automatic (7 hands and two calenders) that maybe it just runs this way. Thanks for your help
