The spring drive, piaget 700p, and Seiko 5s21/5s42 are the only wristwatches I'm aware of with continuous motion second hands. The Omega megasonic would be a runner up, with 1440 ticks per second. The zenith zo342 oscillator is the smoothest production wristwatch that didn't use electricity in its function at 30 ticks per second, although prototypes were made of a Clifford magnetic escapement that used permanent magnets and a mainspring that would have been smoother (pictured). No production run though. The smoothest production hairspring, balance, and lever escapement (traditional mechanical watch) I'm aware of is the 10hz from breguet, which ticks at 20 times per second and uses permanent magnets in its balance pivots. The smoothest traditional mechanical I'm aware of that doesn't use magnets is chopard's 6hz (12 ticks per second), although I believe seiko made some 10hz (20 ticks per second) prototypes that did not come to market. In chronographs, there are plenty of movements with 50hz traditional mechanical movements (lemania, Omega, etc). Tag has made a number of non-traditional mechanical chrono mechanisms, I believe up to 1000hz (2000 ticks per second) if I remember correctly.
