Any timegrapher do Accutrons?

[Alastair]

As above--Any device around that can read the 360Hz of Accutron and 300Hz of ESA types recommended?

Or shall I look for a frequency-counter with high resolution...

The old Seiko QT77 and QT99 could read Tuning forks. But they are hard to find?

QT99 on Y! http://page13.auctions.yahoo.co.jp/jp/auction/r159932911

I don't doubt that Witschi Q1 can do than and much more, if you can part with an arm and eye.

Many Timing Machines with paper strip from that time can test tuning fork watches.

I use a software based version that also can test them. You may have a look at this:

So interesting timing machine software. I notice it comments about a free version but doesn't say where you can get that? So zero website for the company anywhere?
