I purchased this watch because I wanted a wind up watch for hunting that wouldn't break the bank but still be reliable. I am definitely satisfied so far, this is to be an everyday watch. It has some weight to it so you know you're holding on to a "real" product not plastic. I've been using it for a few weeks now and it hasn't let me down. I am afraid of over winding so I give it a few twists a cpl hours every day but for testing wound it to full capacity copiously just to see how long it would run. I have done this a cpl times, best I can tell is between, on avg, about 30-36 hours but Like I said prefer 4-5 twists every few hours and at bed time maybe a cpl more to make sure it makes it til morning. I am not sorry for this purchase in the least. The best test will be if it survives my current hunting season and I will let you know if it does come the end of February.

Update;

Well the watch has survived hunting season with only 1 small glitch. Even though I thought I wasn't over winding I managed to do just that. Since I wasn't able to find a watch repair guy it took me a month of mostly frustration to get it going again. I noticed it wouldn't run for more than a second or 2 before stopping. It would start again once it was tapped witht the edge of my closed pocket knife but stopped again out of frustration I shook it pretty vigurously and has been working great after letting it completely run down. now I only wind it about every 8-12 hours for about 10 twists. been working great again for the last 2 months after a down time of about a month.
