Who Should Pick Which
Pick the Citizen Tsuyosa Automatic if…
- Budget-conscious buyers wanting serious quality under $500
- Those who prioritize scratch resistance — sapphire crystal
Pick the Longines HydroConquest Automatic if…
- Best-in-class 72-hour power reserve at sub-$2,000
- Silicon hairspring antimagnetic protection at an accessible price
- Swiss heritage enthusiasts — Longines' 1832 founding and Olympic/aviation history
- Legitimate 300m dive capability with everyday wearability
- Value seekers — at grey-market $1,350 the spec-per-dollar is nearly unbeatable
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.
Longines HydroConquest Automatic
- ETA-base movement at $1,750 — excellent but not "in-house" in the purist sense
- 21mm lug width — awkward for aftermarket straps (most are 20mm or 22mm)
- 25,200 vph (3.5 Hz) — seconds hand sweep is less smooth than 28,800 vph competitors
- Not COSC-certified — no chronometer guarantee (unlike Tudor or Omega at similar prices)
