Junghans Form A Automatic
- ETA 2824-2 at a $1,000–$1,500 band price — fair value but not prestige movement. NOMOS offers in-house for only slightly more.
- 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
Mido Ocean Star GMT
- 44mm wears large — too big for under-7" wrists
- ETA base movement at this price — fair value but not in-house prestige
- Crystal AR coating can show fingerprints — double-sided AR is a quality upgrade but requires more frequent wipe-downs
- Bracelet quality is adequate not exceptional — most owners report the bracelet is the watch's weak point; aftermarket rubber/MN straps significantly upgrade daily wear
