Well I like to say that the since the 1570 was used on the Sub 5512, the 1570 should not have a 24 hour hand on it. In other words, the 1570 is one of the older predecessors to the 3135 movement seen in todays Submariners.
Your watch should have the 1575 movement on it, which is also one of the predecessors to the 3186 on the GMT today.
The only difference between the 1570 and the 1575 I think would be the 24 hour hand for the 2nd timezone. The much older 1565 movement on the other hand, I think features a "non hacking" movement but I don't have as much expertise on vintage watches as some others do so I may be wrong.
