Yes it is normal, you need to either
1) Get over it, and get used to it
2) Regulate it
3) Experiment with positional variations and see if it helps
4) Only buy quartz

There are 86400 seconds in a day and a watch running at +/- 10 seconds per day equates to an accuracy rate of:
Never thought that I would chime in in this thread but credit where credit is due!
As you know, I could not give two hoots about accuracy, but I noticed this week that my DeepSea (which is worn virtually every day) is 1 minute out. It was last adjusted sometime in August!!!!!!!

86390/86400 x 100 = 99.98% accurate.
I'm struggling to see the problem here.

Guessing you missed this when you purchased it?
"Timing tolerance: +20/-20 seconds per day"
I've been wearing my Pepsi GMT for the last week, after having it in the box for about six months or so. It gained and lost about 3 seconds in that time, so it's running dead on? Mind, I've only had it off my wrist for showers and washing up.

Did you remember to adjust for OCD? That must count for something...

Put like that, I agree .. however it could be assumed that ksl902, being a newbie, may not be familiar with automatic watches and tolerances etc, especially if perhaps he is used to quartz accuracy. ..I am just guessing. To many people, buying an expensive watch you'd think the accuracy improves, but, as many of us on here know, that isn't always the case, especially for watches with mechanical movements.
My new C60 38mm is right at the edge of spec, -20 to -21 seconds per day. If it doesn't settle into something better, i'll have my watchmaker adjust it. I'm not accuracy obsessed, but I know it can do better than this, and I'd rather have it fast than slow.
On the other hand, after 3 1/2 years, my Speedy today timed at +2 seconds after 30 hours on the wrist, so I'm pretty happy there.
My CW Trident C60 (six weeks old) is +15 secs per day (even experimenting with overnight resting positions). It might, perhaps, settle a little as it beds in, but whilst within the movement spec of +/- 20 secs, that's a little disappointing, but ultimately not enough to really bother me to take further action - it's a terrific watch that just needs the crown pulled every few days to sync again.
A similarly aged ETA 2834-2 Elabore grade Hamilton Jazzmaster is running +12 secs, again not ideal but within spec and not enough to worry me - these aren't COSC Chronometers.
By contrast, my Stowa Marine (ETA 2824-2 Elabore) is a consistent +2 secs a day, and JS Watch Islandus (ETA 2824-2 Top) a scary -1 secs.
It could of course depend upon many outside factors, or just dumb luck, but this leads me to deduce that the smaller boutique brands like Stowa or JS Watch are understandably more 'hands-on' with their watches, and it shows in the timing outcome (and price, of course).
I do think many watch collectors are a bit obsessed with accuracy though, it has the potential to drive you a bit barmy & detract from the enjoyment of a piece. I admire & respect good timing, but provided nothing drastic is evident, I can live with a bit of inaccuracy, in the knowledge they can always be finely regulated if I could be bothered. Ultimately, my watches are rotated heavily and are rarely out of the box for more than five days at a time, so there's no real wear duration to be affected by any inaccuracy.
My C60 Trident Bronze Ombre COSC was delivered on the 5th of July. In general i like the watch, my initial reason for buying it was the bronze casing and it is pleasing to my eyes. I did take note of the COSC certification but it was not critical in my decision making, it was just something forming part of the package.
I have done accuracy checks on my two Seiko automatic watches before and was curious about the accuracy of this CW watch. So i carried out my standard (basic) seven day (168 hours) test. Nothing special, i wind the watch to 100%, set it against my reference, wear it to work and when i go out. The rest of the time it lies stationary in a horizontal position. This watch gained 65 seconds over the 168 hour test, thus 9.3 sec / day.
My reference is a time app on my mobile phone, Atomic Clock & Watch Accuracy Tool.
While not the best method to verify accuracy, I left my Limes Endurance II on my watch winder for a month and its Selliita SW200 averaged about -7.5 spd.
