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.
Rado Captain Cook High-Tech Ceramic
- Ceramic is brittle — drops/sharp impacts can crack the case. Full case replacement, not repair.
- 15.4mm thickness — chunky; won't slide under dress cuffs.
- Skeleton dial is polarizing — many prefer a traditional solid dial.
- ETA C07 base movement at this price — you're paying for the ceramic, not the movement.
