After 10 days on the watch winder, The Invicta Grand Diver (Model No. 3044) returns! It was still going, but I had to reset the time because it had lost about 90 seconds or so during those 10 days. What do you guys think? Is that an acceptable variance? 9 seconds per day? What I mean is, that the Seiko NH35A is rated at -20/+40 seconds per day, but that's based on bare minimum / worst probable performance. And you always hear people saying that their NH35A watches "perform well above" that standard. So what is -9? Would you guys consider -9/day "well above" that rating in terms of performance?

55% better? Yeah, I think that qualifies as well above.
