Timegrapher

[ATAR1]

Hooked up my 15202ST 0944ST to a timegrapher...



Is it safe to say that I can hold off on servicing for a bit longer? It's an F series and 10 years old, never been serviced.

Note : I borrowed the timegrapher from a friend. Anyone have the Frederique Constant Analytics? I was thinking about picking one of those up to measure and track the accuracy of my watches.

(I have no affiliation of FC - just curious if it's worth the money)

In order for the amplitude to be correct, you’d have needed to input the correct lift angle.
On the basis that it mightn’t make a huge difference if you’re within a few degrees, then by all means, that looks fairly healthy.

I read somewhere that got one of the FCs, and it was fairly pathetic. Spend the money on a ‘grapher (1900) or if you fancy something smaller/neater and pseudo toylike, then have a look at the Lepsi unit or the One-of accuracy².
