This is a relatively late version of the Valjoux 22 movement, powering a Reference 3336 chronograph . . . probably from the late 1950s.

Can't say "No Filter" on this image, as the original photo has been altered in too many ways to even remember . . . but I like the look of this powerful looking machine.

Next up, we'll have a look at the watch itself.

Anyone else taken interesting movement photos lately?
