The hacking tourbillon wristwatch didn’t arrive until 2008, courtesy of the A. Lange & Söhne Cabaret. In fact, hacking of any sort remained a rarity until the last few decades — ironic, since the primary function of the seconds hand has arguably evolved from a way to assess accuracy into an indicator that a watch is running. Some brands are still in the process of adding stop-seconds features to their basic calibres, and hacking remains scarcer still in wristwatch tourbillons, appearing with regularity only in the last two decades. But building for the waistcoat pocket, historical watchmakers have been stopping tourbillons for almost as long as they’ve been building them, and developed a number of solutions for this problem along the way, each stopping the tourbillon, or merely the seconds, in a different way.

For a mechanical watch to keep the same time across all vertical positions, the “balance complete” — comprised of the balance, staff, roller, collet and balance spring — mu...
