Anyone else have less than great time keeping from these? I've had ETA & Sellita and found even with ETA it had to be high grade to preform well e.g. Sinn uses some nicer grades any experience with Soprod here with Reps or even a GEN would be helpful. I have a SW300 loaded in the watch I use as my Avatar here and it's very smooth just not the best time keeping, runs fast say around 9-11 seconds a day out of the box. I'll see if it breaks in better as I wear it.
