Timing Machine Advice

[margolisd]

Hi everyone. So, a coaxial movement has landed on my bench. Which has made me think, maybe it's time to upgrade from my cheap Chinese timing machine, which can't read coax escapements, to something with a few more features. In particular, I spend a lot of time Dynamic poising, So something that can calculate standard deviation for me would be super useful.

One thing I'm not short on is Laptops. So I don't need an all in one device. I've been looking at the Witschi ChronoMaster which is just a microphone with a USB lead that plugs into a laptop. But is it worth £1,595? Is there cheaper and equally effective software out there? I noticed is that the higher end Witschi machines now have a new feature, calculating the balance wheel's "centre or unbalance". I'm not sure what this means exactly or if it's useful.

Thanks all

I've not used it, but Mark has mentioned in several occasions the software he uses along with his timegrapher. You can have a look here: http://www.delphelectronics.co.uk/products.html

And he uses it in his latest video too:

I´d say: save your money, keep the Weishi.
1. It will show the correct rate of Coax watches, too (if beat rate is right).
2. It will show a wrong amplitude value (some percents too high with right L.A.)
You can compensate (2.) with a modified L.A.

Sufficient for dynamic poising: you will need
- about same amplitude in all vertical positions (flawless escapemen!), 
- to know which position shows the highest/lowest rate,
- to know the theory behind the procedure
