  1. Has anyone ever used a case press like this one: https://www.ebay.com/itm/GF8721-Snap-Back-Watch-Back-Case-Press-Spiral-Type-Closer-Tool/142877470395?hash=item2144292ebb:g:EwkAAOSwczhbU1CG It looks reals sturdy from the pictures, but i would like to get someone's first hand experience.
  2. Ok, I downloaded the file and played it. The method I used was to plug a cable into the output of my soundcard and plug the other end into the microphone input. The results were a rate of -5.0 seconds per day.
  3. Ok, when I get back to my computer I will try. My calibration was done using the method suggested in the Watch-O-Scope manual. First I measured the rate of an analog Quartz watch I had using a Witschi twin analyzer. Then, I placed the watch in my microphone and rand a 600 second test, with the beat rate set to 3600. Then the difference in the two reading were entered into the rate correction field of Watch-O-Scope. It turns out that the sound card in my old thinkpad laptop required a correction of -2.37 second.

  4. I think that a pre-amp would definitely give a better signal, I might try it with one and report my results. So far I am happy with it as is, I did do a comparison between my setup and a Witschi twin, and the results were spot on. Sent from my iPhone using Tapatalk
  5. I bought them from http://www.alliedelec.com/ The USA store was out of stock, so I back ordered them and it took about a week to get them.
  6. I have been greatly enjoying this thread, and I would like to thank Stefan and everyone who cotributed by posting their projects and comments. On page seven of this thread Mark posted some photos of the inside of his microphone, and on that same page someone else posted a link to a piezo sensor similar to the one in Marks' microphone. I followed the link and ordered the sensor, installed it inside an old watch microphone I had and the results are better than I could have hoped.

  7. Thanks, I am looking forward to this new endeavor and will post regualrly on my progress. By the way, I am woking on a microphone for the Watch-O-Scope software. When I am done I will compare next to one of the swiss made units at work, if anyone is interested.
  8. Thanks for the warm welcome, I have a few watches that I have to get in workin order then I will post some pictures for all to see. I do not have much experience with mechanical watches, however I am very interested and have started buying tools and currently I am finishing off my watchmakers desk. About two months ago I applied for an internship position at a local watch service center. They called me this week and I am due to start on Monday. For right now I will be working on quartz watches, but I will be getting training from the current watchmakers. I got a tour of the facility when I went for my interview a few weeks back, and they gave me a few watches to change batteries, remove links etc. If anyone has any advice for me I would greatly appreciate it.
  9. Has anyone tried to use a Windows Tablet with the Watch-O-Scope software, I am particularly interested in how the built in sound card performs.
  10. I have been reading posts on this forum for about two monts now, after finding Mark's videos on youtube. I look forward to participating in the discussions and contributing wherever possible. Thank You
