  • Excellent, Unique Watch. Sweet ; )

    Excellent watch. Looks and feels great!The strap seems nice and solid. I was able to remove 3 links, easily to make it fit. I don't have a big wrist and the face of the watch is smaller than the dimension make you think, because of it's contoured, and comfortable shape.The buttons are nice, solid and responsive.Great clean finish, delivered in a nice clean unbranded metal box.Was easy to set and is not difficult to read.LED's are nice and bright, even on the lowest brightness setting and all appear to be neatly lined up!
    I haven't tried to take off the back yet to replace the batteries. So i can't comment on how difficult it is. I have never owned a watch that was easy to get into, so I don't imagine this one would be either.Countdown timer would be good feature and fun to watch.
    Excellent watch, excellent deal! It will have people talking. No reason not to get one and give out as great gifts! I am really happy with this watch!

    All the LED's work, except for one row. I think this was caused by my experimenting while trying to find the pin layout. The product was probably fine. Luckily I do not need all 8 rows for my project. I intend to use this for a 2 digit display.
    I received a 16pin version.By testing I found that it was connected in the following way:Rows (+): pins 6, 2, 7, 1, 12, 8, 14, 9Cols (-): pins 16, 15, 11, 5, 10, 4, 3, 13The bottom text says:pin--45.72--0.8NL23881A
    I would but one of these again if I needed it.
