How to adjust accuracy of Asian 2813? (pics supplied)

[watch123]

Hello, I just bought a Beginmariner LV from Josh, and while it's absolutely beautiful to look at, it gains about 1 1/2 minutes per day. I've already got the caseback off, and would like to adjust the proper lever inside, but am unsure which of the two is correct to move.

Previously I saw this photo posted about how to adjust a movement:

The instructions were "Moving tab A away from tab B will make the watch run faster (moving A closer to B will slow it down)"

Looks simple enough, however, the shape of tabs A and B seem to be the opposite configuration on my 2813 movement. Wide tab with small screw is on top, and the smaller tab is under it:

Which one should I move to slow the watch down a little bit? (I read touching the wrong one can mess up the "beat" of the watch, and of course I don't want to do that)

Thanks for any advice.

Move the lever with the 2 brass pins in it, TOWARDS the other,

This has the effect of lengthening the hairspring, thus slowing the time.

The other lever ( with the screw in it ) anchors the hairspring.

Not much , start with half mm.

Unless you have a timing machine it is going to be trail and error.

Hope this helps.

Hey,

Sorry I didn't update this earlier. Just wanted to say thanks for the reply, the info definitely helped. I was able to get the watch running much more accurately. Thanks!

One thing to watch out for is when you adjust lever A is that lever B should remain FIXED, otherwise you're in for trouble (I found out the hard way)...
