My new grandfather (clock) ;-)

[MikeEll]

I was lucky enough to have the opportunity to buy this beautiful grandfather clock made by Comitti, London.  It’s rare I see a clock able to maintain +/- 1 or two seconds a day, but this one does so consistently.

being weight driven as opposed to spring driven you have a constant driving force, so good timing is often the case, especially if the movement is in good order. 

On another note whats the app you are using there for testing?

Antique Longcase clocks are all weight driven. Some of these modern movements are manufactured westminster chime movements and spring driven and screwed into a case that resembles a Long case. They are not true Longcase clocks. What we have here is a modern Longcase case with a modern westminster chime movement weight driven. Americans refer to these clocks as Tall Clocks.

thanks for that.  I'm using the ClockMaster app for iPhone/iPad, connected with a Peterson PitchGrabber microphone clip.  Its quite a useful tool.

Yes, this is one is a rather nice Hermle movement.  I'm very happy with it.

Heard a lot about the clockmaster app, I have been looking at the microset system by Mumford, but it turns out to be very pricey when you start to add a couple of bits onto it.

I still use my ear and at least 3 weeks of testing before I send a clock back to a customer but i do like a gadget

Yes, I can also get things pretty close by ear. This helps with getting the clock fairly close within the first hour or so. If it's in pieces, allowing you to count the teeth on various wheels, you can determine the required rate for the clock and simply dial it into the app when ready for testing. It significantly reduces the lengthy regulation time.  I think it cost me less than £100 all in, including the microphone.
