Hike... I just received my YM from Trusty today, so it's too early to comment on its time accuracy, but the movement did stop and the minute hand moved back a minute or two after I fully tightened the crown. I released the crown a little and it started back up fine. But, the rotor is really noisy, is your YM loud as well? In the four hours since I synched the time with time.gov it appears to be running just about a second fast.
Would you be willing/able to post a photo or two of the black sub you got from Andrew? His photos always give the watches a dull appearance to my eye, but the vast majority seem to be pleased with their purchases. At the price he is offering them for, and with waterproofing included, I'd like to pick up the Black SS and the LV. I have one of Joshua's beginmariners and really like it, but his movements are no longer running at 28,800 so if Andrew's are aesthetically similar and boast waterproofing, it would make more sense to go with Andrew.
