Omega Seamaster, "Pre-Bond" Ref 396.1062 Date adjustment question

Hello,

Newbie here, I hope you can help me out:

I just received a vintage Seamaster Professional 200m Quartz Ref. 396.1062 and I am wondering about the date adjustment:

As far as I know it should work like this on this:

• there are three positions of the crown
• 1st position when the crown is unscrewed, no adjustment
• 2nd position: pull out the crown: quick adjustment of the hour hand
• 3rd position: pull out crown further: adjustment of minute hand

In the watch I received the 2nd position changes the date only, no movement of the hour hand, 3rd position works as mentioned above.


Has anyone experienced this or knows about if a different movement was used in some of these watches? Or does it mean a non ETA/Omega movement was built in this watch?

(I added some photos of the watch in case that helps)

Thanks!

Thanks for your answer, I already thought that
