Here's one of my favorite watches. It is powered by an ESA 9154 with a Hacking feature and calendar, and this thing keeps time within 3 seconds a day! Its as good as any of my Omega certified chronometers and I got it for about $40...a little maintenance and a new crystal/gasket and here it is!

Yes I have a picture of the movement but not on this computer. The watch has a 13-Jewel transistorized movement that contains a copper coil over which the "conventional" balance wheel (and swiss lever escapement) is impulsed due to the magnetic force created. It ticks at 28,800 bph. I have photos of the movement on my other computer and will put some up later tonight. I have to remember: ALWAYS put pictures of the movement!

Yes valves! The ESA dynotron wasn't on the scene that long before quartz movements spread themselves everywhere, but the ESA-type electronic movements have proven themselves robust and capable of excellent time-keeping characteristics. Like I said, this little engine keeps time precisely within +/- 3 seconds a day when I compare it to the NIST clocks here in the U.S. Thanks for the replies fellas!

      Battery

      Try putting everything back together and closing the back cover. I think one of the two springs has to contact the metal casing to ground the casing. So when you press the button, it will touch the contact on circuit board and close the circuit.

      Stem removal after fitting hands

      By PeterS · Posted

      Yes, the seconds hand is the longest and goes almost to the edge of the dial. I can’t quite picture it how you do it on the rubber pad

      A don't think so it leaked or damaged it because the watch itself works it just the buttons ain't working not connecting with the circuit board have taken more pictures of where the buttons makes contact with the circuit board.

      Stem removal after fitting hands

      By Neverenoughwatches · Posted

      I think what peter means oh is once he has fitted the hands and  checked for  alignment if them and that they dont foul, how does he then hold the movement to remove the stem in order to case up. The dial cannot be laid on a cushion or in a movement holder as the hands will get damaged. This can be quite tricky for a beginner, what i do is  to stand the movement on edge on a rubber pad so it doesn't slip. Hold the top edge with one finger then my dominant hand uses 3 fingers to press the stem release and flick out the stem. See below peter, leave off the second hand as this is the longest and gets caught the most, then fit it once the stem is out. Alternatively place the movement in one of the cup style holders, i imagine this is what they are designed for. They only touch the very edge of the dial.

      Yes I understand that. What I’m asking is, after the hands have been fitted, it’s been checked that the hands do not touch etc. then I need to remove the stem to fit the movement in the case. I have the push type, I need to turn it upside down and push the setting lever post and pull the stem out. But of course the dial and hands are in place and I have a glossy dial with lume dots and I do not want to cause any damage while it’s upside down pushing on the post of the setting lever.
