    Truing Caliper

    Good hint, Karl! I will try that method next time (if not forgotten till then). For bending I use a pliers with brass tips similar to this one: Bending in the caliper is questionable in my eyes, as it is stress for the rivet. Finally, none of my calipers are used any more: now I test in the...

    Is flattening a balance pivot an acceptable Wostep Standard

    He did, e.g. here: But it rather looks like a thank you for his sponsor B. Not forgetting to mention, to do it on medium quality or less watches only. Frank

    Imhof quartz: Battery ideas for 1.35 volt replacement

    Imhof quartz: Battery ideas for 1.35 volt replacement

    Congratulation :-). However with this adapter and the tiny 357 you lost a lot of capacity / running time. I suspect, this pricey adapter contains nothing more than the schottky diode (<$0.05) that David mentioned above. Frank

    Watch Tuner Timegrapher

    Marv, his reply was, he uses "Parallels" for Windows programs, but an external microphone only works via an USB soundcard. Unfortunately I cannot help further, as I do not use Mac computers (except my Iphone). But also with recent Windows computers it became tricky to persuade a mic input...
