Just to note out of my experience with one, after owning it for about 2 months. I wore it about 5 days a week, always had to hand-wind it because the rotor is very light and can't rotate. The crown was ruined from the daily hand-winding and simply fell off and has to be replaced. You can get the watch for something less than 20 euros and is very good for the money - you need about 50 euros to get something better, so it's up to you. When I replace the crown it will probably be more robust with some threadlocker in place. Also, even though there is space on the stem for an o-ring, there was none and the gasket seemed to have no grease on it so I will also improve it's water resistance as well (I would not go swimming with it anyhow).I don't have one, but they do seem to have some sort of stainless steel case (304L?), instead of a cheap alloy case that is common in the price range. The movement is a 17 jewel, Tongji automatic, expect about 30 hrs PR fully wound. The Tevise T801 is rated 30m WR, so don't take it swimming. I like the wide pallet of color choices, and this one is unique AFAIK.
