Update 5/11/2013 (two months later) - I found that the winder had stopped today, my watches were wound down. I cycled it and it began to move slowly so I turned it off again and let it stay off for a few minutes and turned it back on, and it seemed to work... now I am waiting for it to stop running.
Updated 5/24/2013 - It must have been some monkey in the wrench, it has been working OK since that glitch a few weeks ago. I will keep an eye on it and write a review in another month or two.
Update 8/23/2013 - Well the winder did stop running around the end of June. However AceTimer stands behind the winder with a 1 year warranty, and were great about fixing the problem. Generally speaking, a winder won't last for years, but buying from a company which actually supports their product is the best I feel a consumer can do. I have the winder back now (actual turn around time for the repair was about 2 weeks), and it is back to keeping my Seiko running on time.
