I only had it for a little more than a week. From what I can see, it gains about 3 seconds per day when chronograph is engaged and less than a second when it is not. Is that normal? It's just a little counter intuitive for me

 

Are you constantly timing things for 24 hours or more?

 

That's what I would expect with the added load and amplitude drop. Still well within timing specs.

It's a Speedmaster!

 

I know, it's pretty much on par with the METAS test result, which I didn't know you can check (IT'S PRETTY COOL!!).
I just thought with the chronograph engaged, it would gain less...
Oh well, not complaining here XD
