Also the sweeping second doesnt seem perfectly smooths, looks like its moving like 3 times/second. Is this normal?

The reference 1002 used calibers 1560/1570. These were not fast beat calibers like those used currently, they beat at 18000 bph, and the second hand would appear a bit more choppy than a modern Rolex. But they were excellent calibers and should give you a lot of years of service. I don't know if they had a hack feature, I'm sure someone will come along shortly with that information.
Just double checked and the cal. 1570 is 19800 bph.
