Movement Stories: Chronograph Service - Venus 188

As complications go, the chronograph is both prized and something of a Mt. Everest for amateur watchmakers. In this article, I’m going to walk through re-assembly of a “typical” (if there is such a thing) cam-driven vintage chronograph movement, the Venus 188, to show that - if you’re systematic - there’s nothing to be afraid of. I’ll also talk about adjustment and tuning of the chronograph functions.
