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 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
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 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)
