Apologies upfront - I haven't used a Lepsi. I can see they would be very useful if you're buying a watch face to face to check it out, but a few things come to mind.watchaholic wrote: ↑Tue Mar 26, 2019 3:11 am Anybody have any experience with a Lepsi Scope? Kind of pricey but might be an alternative to the chinese instructions. Would like to get into this process of regulating but still have a lot to learn.
If you're going to regulate a watch, you need a microphone stand that lets you hold the watch safely with the back removed. The proper timegrapher microphones do that. The Lepsi device won't I think - it's just like a contact microphone.
Their blurb says it will calibrate your computer/ipad/android device. That's gotta be a good thing, but phones and pads especially aren't renowned for their short term clock accuracy, as it can depend on what other processes are going on - a lot of them being things you have no control over.
If you want to try out timing stuff before buying something bespoke, one option would be to download TG (https://tg.ciovil.li/) which is freeware, and runs under Windows and a few other OS, (not sure about android or IOS though). Add a cheap Guitar pickup (mine was £2.76 !) and you're good to go.
It does more than timing by also showing you the escapement noise graphically. What you do with that as an amateur is moot, but if you're at all geeky it's interesting and it could be useful to snapshot and send to your watch repairer for advice. It also will do calibration, although in a different way, but the issue of clock consistency is still there I think. With that simple setup you still don't have any secure way of dealing with the watch with the back off.
I wrote the comment about the clarity of the Chinese instructions and to be fair, that is the most impenetrable bit (!) Although those devices are deprecated by some (but not all) professionals who have their uber-expensive Witschi stuff, they do a surprisingly good job and are easy to use. You can't calibrate them yourself, but they have a dedicated processor to do the timing, and mine certainly gives reliable results.
