How can one tell what the movement is? I have saw this:

"The first Sebring used an A. Schild 1564R movement; the second–introduced in 1967 with an updated design–used a Valjoux 7711 movement."

Also are there any operating instructions? This was supposed to show timing in 100ths of a second. How does that work?

Thanks (as you can tell I know next to nothing about these watches except that they are beautiful precision tools.)
