Power reserve test on my new 3861 Speedymaster Pro.

No, but you did have power reserve issues until the community convinced you that the proper way to wind the watch is to turn the crown until you hit a firm, hard stop and not to rely on 'kick back of the crown' or hitting some sort of 'initial resistance' as a signal to stop. I suspect your white dial was sent off prematurely before the proper procedure was understood and accepted. Your OB didn't understand the procedure either and sent it off to satisfy your frustration. They should know how to wind a manual watch, but they seemingly didn't. At this point it doesn't matter, you had the inconvenience of not having the watch for two months but now it is back with you and both are running 60+ hours on a full wind, which is normal. Enjoy them along with your new FOIS which you will find is easier to wind due to no crown guards.

The new FOIS was still running when I wound it and the other two this morning. I had not touched it since picking it up Friday at 11 am. So 67 hours at least. Impressive.

At what time did you wind it, 6 am?

Yes
