Hello friends, it's me again, Thom the watchmaker. I am a professional solder, SMD components are no problem for me. Here are some pictures of my finished soldered watch. Front and back. Please see for yourself - the clock is very clean and soldered without any short circuits. Checked all connections according to the schematic. Nevertheless my watch does not work. After switching it on, not a single LED lights up. The clock is dead, nothing works. The STC-Cip gets very hot. Unfortunately I can't give the seller a positive evaluation, because the watch doesn't work. Pure waste of money and work. I ask the seller to completely rework his product and offer the watch with a better instruction manual with pictures. If the watch works afterwards, I will buy it again, not before! I like the clock, if it works. I expect the seller's guaranteed refund of the purchase price. Best regards Thom

    Please attach the SMD chip installation instructions.
    I, too expect the seller's guaranteed refund of the purchase price.
