Who Should Pick Which
Pick the Junghans Form A Automatic if…
- Enthusiasts wanting proven Swiss/Japanese quality in the $1,000–$2,000 sweet spot
- Those who prioritize scratch resistance — sapphire crystal
- Dress watch seekers who want understated elegance
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
Junghans Form A Automatic
- ETA 2824-2 at $1,450 — fair value but not prestige movement. NOMOS offers in-house at $1,680.
- 38-hour power reserve — leaves unworn for a weekend and it's stopped by Monday
- No lume / dress-only — not versatile for active or outdoor use
- Limited US distribution — difficult to try on in person outside major cities
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
