Lumination is TERRIBLE, barely exists. Everything else is very good.
I bought two of these (blue and black) and returned both. I buy a luminous watch because there are times (like driving at night) when I need to see what time it is in the dark. I charged the lume of these watches on the window sill in direct sunlight for hours. Tested in a totally dark room, the luminescence was minimal to start, and I watched with disappointment as the lume quickly faded entirely away within a very few minutes. Otherwise, this watch is very nice and of high value. It should be noted that I am not one of those nitpickers that unreasonably expect a watch at this price point to have a minute hand that precisely hits every marker on the dial and all the other finest hallmarks of absolute perfection that one might expect of a jewelry timepiece costing ten or twenty times this price. My requirements for a watch are accurate time, durability and good lume. I cannot settle for two out of three.  So I gave it three stars out of five. I am surprised the poor lume was not mentioned more in other reviews. Perhaps I had two flukes, or lume is not important to others.
Rating: 3 stars
