Just received my C60 Anthropocene GMT two weeks ago and I'm very happy.
Just wondering what the grade of the SW330-2 movement is that has been used.
It seems it is most accurate dial up position at night. Because of the great lume I wonder if other positions affect accuracy. Like to look at it when I wake up at night
Would appreciate your thoughts!
1. Special grade is the lowest grade (for the SW200 for example there is a standard grade). Unless otherwise noted CW uses the lowest grade.
2. That is +- 5 sec/day average, 20 s/d max deviation and +- 15 s/d isochronism
3. The positions are listed as CH, 6H, 9H, 3H - dial up, 6 up, 9 up and 3 up.
By the max deviation no single position should be more than 20 sec from any other position. So yes, there will be some deviation between positions. How much will vary from movement to movement but they should all meet the spec.

I finally found a link with specific info related to the sw330-2: https://www.sellita.ch/index.php/en/movements. Click on sw 300 and scroll down to sw330-2 link.
This page includes a downloadlink to all technical specs, I guess almost identical to sw330-1. It even mentions different finishing styles.
Anyway, my preferred resting position at night, vertical with crown right(12 up) is not a position that is mentioned to be within accuracy-margins(with the bracelet I can almost perfectly position the watch this way like an alarmclock ) Although it might be a position that resembles vertical with crown up(3 up)

There must be a reason that it is done this way. It is within the realm of possibility that dial up and 12 up give the same results on average. I don't know for sure but you could do a few nights in each position to verify it.
