Materials Face-Off

ComponentJunghans Form A AutomaticHamilton Khaki Field Automatic
Case alloy

316L stainless steel — standard grade for mid-range watchmaking. Hypoallergenic, corrosion-resistant.

Stainless steel, brushed finish. Hamilton does not publish the alloy grade for this reference.

Crystal

Flat sapphire (Mohs 9) with anti-reflective coating on the underside — provides excellent clarity with minimal internal glare. Note — Unlike the Max

Mohs 9

Verneuil-grown sapphire, single-side AR coating.

Caseback crystal

Tinted mineral glass (smoke/grey tint) — provides partial view of the movement while maintaining a subtle aesthetic.

Super-LumiNova on the hands and hour numerals. Hamilton lists "Super Luminova: Yes" for this reference and does not publish a grade, so none is claimed here.

Dial material

Brass-base dial with matte silver lacquer finish, embossed (stamped) square minute track producing three-dimensional relief.

Full-grain leather (varies by reference).

Strap

Black calfskin leather with polished stainless steel pin buckle. Leather is adequate quality but not luxury-grade.

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 Hamilton Khaki Field Automatic if…

  • Strong value proposition under $1,000 with quality construction
  • Active lifestyle wearers — 100m water resistance handles swimming and water sports
  • Weekend warriors — 80-hour power reserve means it survives two days off the wrist
  • Those who prioritize scratch resistance — sapphire crystal
  • Military/field watch enthusiasts who value legibility and durability

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

Hamilton Khaki Field Automatic

  • Same H-10 / C07 movement as Tissot PRX and Mido — paying brand premium for the Hamilton heritage
  • 3 Hz "slow" seconds beat (visible 6 ticks/sec vs. 8)
  • Strap quality is adequate, not exceptional
  • No hacking, but movement is auto-only (no hand-wind on the 80h variant — older H-30 caliber refs had it)
