Citizen Tsuyosa Automatic
- No hacking seconds. When you pull the crown to set the time, the seconds hand continues running. Setting precisely to-the-second is impossible. The single most-cited Tsuyosa complaint.
- Unidirectional rotor. Only winds in one direction; reserves take longer to build than bidirectional movements.
- Modest accuracy spec. ±10 to +25 sec/day in practice is the realistic band; significantly worse than the Tissot Powermatic 80.
- Proprietary endlinks. Limited strap-swap options.
Hamilton Intra-Matic Auto Chronograph
- 14.6mm thickness honest but tall.
- Not column-wheel — cam-switching 7753 architecture.
- H-31 isn't in-house in the strict sense.
- Lume is modest.
