Seiko Bellmatic Lift Angle Documents Are Incorrect

Тәжірибелік нұсқаулар және стиль

Having recently seen a discussion regarding the correct lift angle for the Seiko 4006 'Bellmatic' and having one being serviced currently it seemed a perfect opportunity to test it and see what the correct lift angle is.
It's certainly not the 58.4 claimed by most online resources.

    Really useful video, thanks, and excellent tip on the slow-mo. I'm quite new to the world of watch repair but learning a lot from your videos.

    Glad it's useful. The slow motion feature is great and standard in most smartphones now. Another way is to mark a dot with a permanent marker on the opposite arm to the most visible nearest you then watch for that reaching the side nearest you on both swings. You can remove it with IPA on a cotton bud after.

    Excellent video. I've never doubted any of my massive lists of lift angles so, I scoured them furiously to check 4006 and 4006A, and OH DEAR, 58.4 degrees! Thanks for the heads up but my confidence is broken. The world is no longer a safe place to horolog-tinker. I have always held great stock in my lift angle lists but no more! The amplitude is important to me to gauge the success of every watch I service and now I shall be haunted by the fear of lying lift angle sheets until I check them all.

    Believe me, you're not alone. I always trusted the lists until I happened across a discussion on this very movement. Having one handy was the ideal opportunity to check. Might be a worth a double check on the less common ones in future.

    Good to watch the technicalities. At my level of understanding. Clear as mud. Fun, none the less.

    Lol thanks. It's simple to use the 180 degree rule to calculate if the lift angle is unknown. Always a handy thing to know. I keep meaning to do an in depth of the timegrapher but finding the time (haha) is impossible. Long and short of this is that if measuring at 58 reported amplitude is incorrect.
