Generally speaking, yes. My most precise watches, such as the COSC certified Breitling Premier B09, also do fantastically well on the timegrapher.
Now I'm bummed a little bit. They had just sold the one they had in stock, and their inventory wasn't updated, yet. I was hoping to have it for my long walk tomorrow. Not a big deal, and I'll be happy to have one that's never been handled.
I love that watch, and I kind of regret not buying it when I had the chance. I think it's very interesting, and it speaks to me as someone with B.S. and M.S. degrees in physics.
