Good day, guys! This is my little way of giving back to this wonderful community. We usually receive for repair a watch handed down by a father to his son. In this case, its a watch given by the son to his father - a Seiko 5 from the early 1990s. The watch has seen better days, with its hardilex crystal beaten and the watch not moving at all regardless of the amount of shaking you give it. The hands are corroded and the dial mounted on the movement using contact cement. I'll skip the disassembly and show you how the Seiko 7009 movement works. The Seiko 7009 technical guide is easy to find on the net though. First to be mounted is the center wheel that drives the cannon pinion. After which I install the escape wheel and the center wheel bridge. The third wheel and fourth wheel is installed next. Note that the fourth wheel drives the second hand directly. Then the click comes next. Prior to installing the unified barrel and train-wheel bridge, you have to install the pawl lever and first reduction wheel assembly. The assembly is held in place by the first reduction wheel holder. Take note of the orientation of the pawl lever. I find it difficult to install the barrel and train wheel bridge while ensuring that the click spring doesn't get in the way. <end of part 1>
