Issues with mine are starting to show now after 3 weeks of ownership. its been on my wrist daily and I have no winder- but when i come home from work, I take it off and put it on the counter with my phone, keys and wallet- say around 6pm. If I do not put it back on the wrist by 6:30 am, its dead. I even moved the date change to happen at 12pm on my watch so it happens at noon instead of midnight.
Even before I got it, I knew this might not be the most reliable movement - so I contacted The Zigmeister to figure out how to get into his list, price, etc- then I bought an ETA PO so I had a pretty suitable back up....
I'll assume that a decent cleaning and oiling of this movement should take care of my issues.... I hope.
