  1. Even though the garden is screaming for attention one has some spare time to continue my magical journey through the heap of quartz movements. This time it is the ETA 251.262 Chronograph which can be found in watches like Breitling Colt Steel, Certina DS FIRST, Longines Hydro Conquest and so on.. I'm quite surprised of the amount of quartz movements which are getting a new life after a good clean and service. As usual all the files are in a PDF format, and all pictures are original.

  2. Just as a curiosity I once in my lifetime worked in the automotive industry and if I don't remember wrong I once went to Finland to see how the Saab production went. And at least then Valmet was talking about building Porsche Boxter and Cayman in the feature line .. and I guess they did between 1997 - 2011 when the production was moved to Magna Steyr in 2012.. one should never say never as Bond said https://en.wikipedia.org/wiki/Valmet_Automotive
  3. Sorry forgot about the movement porn bit... unforgivable I know. This one has an little bit odd one .. lets call it a Certina 28-10 humping around with the odd oscillation of 19800A/h ..
  4. Well the plot thickens as I remember from school the V in german is pronounced as a F so it would sound little like FolksWagen in an harsh way.. Here is an Certina Waterking in a VW, matching in every way down to the dust specks on the glass... why have a digital clock in your car when it can look like this.
  5. The clutch should be straight and lying flat onto the movement, there is a small chamfer on the top and recess for the hammer..
  6. Now it's warm enough to begin cultivating the flowers here too, we been struggling for a few years to fill out the 4 acre garden with plants and flowers. The right tools for the work makes wonders.
  7. The 7750 is quite straight forward to work with I add some pics which shows you what to look for and help you in the progress.. Good luck and keep up the good work!
  8. I can't see why it would run backwards but there is a testmode where it seems to go backwards ..maybe it's stuck there ? ETA-988.333.pdf
  9. Took a look at an slightly older one it had a ETA 988.332 this movement is an ETA 988.333
  10. Seems to be in place.. On the wrong device to see clearly but will upload a pic which you can compare with..
  11. I'm not sure it makes any difference what way it's positioned when the graph looks like this, the suspicion OldHippy had from the beginning seems to have been spot on since this looks like a typical dirty/magnetized hairspring. Just a thought before doing anything else .. clean and demagnetize...
  12. For some reason I forgot how the stem in the 7750 went in so lucky me I had a couple of brand new movements lying around so I didn't have to take a watch down just to still my curiosity. Almost immediately when I took the stem out it al came back, as you see on the picture the stem will with ease goe in a bit but not the whole way without some force, if you push the stem release button slightly it just propps in like a coin into a peepshow booth. Think it might have to do how the stem is designed and in how good shape the setting lever is in. Adding a picture of the stem too...
  13. From the video you can see the yoke isn't moving at all, this indicates it might have jumped out from the groove in the sliding pinion and that is why there is no spring action when you put it in the Winding position.
  14. If you decide to wait Otto Frei has sometimes good tips and trix in how to choose things and in this case they have written a couple lines about it on their page, Reading is Always a good past time. http://www.ofrei.com/page820.html
  15. The hairspring often are matched by what they call vibrations, so the first you should look so it vibrates/oscillates at the same frequency. Next you have to match the diameter of the spring with the diameter of the balance Wheel. If they are the samme then it might work. next you look at the balance staff, If these are the same the chances for success has increased enourmously since the collar on the hairspring will sitt tight on the balance staff. At RANFFT you can find the most except the diamater of the balance Wheel. http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&2&2uswk&ETA_2390 http://www.ranfft.de/cgi-bin/bidfun-db.cgi?10&ranfft&2&2uswk&ETA_2408
