I am not a watch collector but my stepdad was and I am selling 2 of his watches (this and his SINN U1). Therefore, I dont know too much about the watch but ill put together what I do know:He was a luxury watch collector and this watch is 100% real. He was very proud of his collection and would never buy a fake watch. (I am also an ebay seller for 15 years, I would never sell a fake item)The watch self winds when you wear itHe had a rotation of many watches he wore. I dont think he wore this one that often - I would estimate maybe 30-50 times.I cannot find the box or any documentation. He kept all his watches in felt sleeves in his drawers. I assume the box is in the attic but I cannot find it.There are no other bands that come with the watch - what you see is what you get.Here are the markings on the back:UTS - MunchenNR-001UNITAS 6497STAHL 1.4305200 MSAPHIRSeventeen; 17 JewelsSwissI do not see any major flaws to the watch, just normal signs of some light use. Please look at the pictures closely to get a better feel for the condition.
