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!

      B-Dip residue?

      By pent · Posted

      So I was cleaning an especially dirty balance spring with B-dip because several turns were sticking together.  However, after a wash and dry, it seems there are more turns sticking due to the B-Dip.  I can see it clearly in-between the spring turns and it is not evaporating.  I even stretched the spring upwards a bit to let them air out and they continue to stick.  This is after two washes.  You can still see the liquid between the springs. Not sure if anyone has seen this, but I don't know if this is an indicator of my dip going bad or being contaminated.  I would rise with IPA, but the stud and collet aren't pinned--they are either glued or shellacked so I won't risk it.  If I keep seeing this, I'll probably switch back to a heptane or naphtha for this type of cleaning, but I wanted to see if anyone else has seen this with B-Dip.

      Very useful Video

      By mikepilk · Posted

      I only watched the start, but he's out on magnification by a factor of 10. It's 7X to 45X, not 450X

      Stem removal after fitting hands

      By mikepilk · Posted

      It's one of those tools like screwdrivers and tweezers, where it's worth spending more for the quality. And it gets used all the time. At about £20, the 4040 is not expensive for Bergeon.  When putting a watch in dial down, you have to be careful not to catch a sweep second hand, but once secured, life is easy - two hands available to work on the stem.
