You may see that improve. Mine started out, I believe, around 3 seconds fast per day. Today, last day of the month, it will be 5 seconds fast
for the month. One month it was 4 seconds fast. That was the best it's done. I've had it as much as 10+ seconds fast for the month. I'm sure how it's worn has an effect and causes the variation.
Impressive movement in the SDc.
