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 Master Collection Moonphase if…
- Weekend warriors — 72-hour power reserve means it survives two days off the wrist
- Those who prioritize scratch resistance — sapphire crystal
- Dress watch seekers who want understated elegance
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 Master Collection Moonphase
- ETA A31 base at $2,450 — though Longines-exclusive, the architecture is shared platform. Some buyers expect in-house at this price.
- 30m water resistance — strictly dress watch use; no swimming, no shower
- Moonphase indication is rough — like most "simple" moonphase movements, the 29.5-day approximation is imprecise vs. actual 29.53-day lunar cycle (requires ~1-day adjustment every 2.5 years)
- 3.5 Hz frequency is unusual — not as smooth as 4 Hz peers
