I'm not a watchmaker but if you have to ask, I would take it to one. A stands for Avance (speed up); R stands for Retard (slow down)

As the man said, if you have to ask............

The regulator is in about the right position for a correctly timed movement. If the watch is gaining/losing an unacceptable amount of time it should be checked by a watchmaker to see what the problem is. I may be more than just an adjustment to the regulator.

There also looks to be an issue with the click.

I don’t think the balance is moving, therefore the mainspring is down and no power to the movement.

Labour rates $200.00 per hour if you watch.
Labour rates $250.00 per hour if you have worked on it.

Saw that, thought that there should be the teensiest bit of roll-back there though.

A quick follow up, after adjustments my Seamaster 30 now runs with +3,3, + 3,7 and +2,6 in the three accuracies test I did, very happy and pleased with the Omega from 1962 😀
