I wore my Sub41LV on a extended 1 month vacation every day from diving to theme parks and it was a rock steady -0.50 a day. So consistent that it never deviates more than 0.50 to 0.25 seconds a day regardless the activity even at home running a chainsaw to whatever. Incredibly consistent.

FYI.. Most all of my watches are always kept on a custom multi head winding box running but I tend to only keep 4 watches at a time running as that is the amount I like to rotate/wear.

(1) You say that your 7 watches were all regulated in the range of -0.05 to 0.0 sec/day?
All 7 watches in a range of 50 milliseconds/day?
How do you know these movement regulation values?

(2) You say that - over a period on 1 month - your Sub41LV never deviated more than 0.50 to 0.25 sec/day?

Can you explain how you verified the movement regulation (-0.05 to 0.0 s/d) and how you measured the perfect timekeeping (0.50 to 0.25 s/d)?
