What do you mean "off" not accurately marked or just crooked? I don't really like them (tachymeters on dials) - never had a car (or anything else for that matter) that needed to be clocked at 400 mph and I never had a car without a speedometer!
But I love the colored hand that marks the seconds - on most chronos.
Just got one also, I love the watch. Congrats. I like it on the SS band.....I'm thinking of a BOB blue croc-style deployment for mine. Overall I think the watch is pretty accurate. Good job on the pictures.
