Materials Face-Off
| Component | Junghans Form A Automatic | Seiko Presage Cocktail Time |
|---|---|---|
| Case alloy | 316L stainless steel — standard grade for mid-range watchmaking. Hypoallergenic, corrosion-resistant. | Stainless steel (Seiko's standard mid-range alloy) |
| 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 | Hardlex (Seiko's proprietary hardened mineral) — not sapphire (a cost-control decision to maintain $425 price point) |
| Caseback crystal | Tinted mineral glass (smoke/grey tint) — provides partial view of the movement while maintaining a subtle aesthetic. | None (intentional — dress watch design) |
| Dial material | Brass-base dial with matte silver lacquer finish, embossed (stamped) square minute track producing three-dimensional relief. | Multi-stage sunray brushing radiating from center; applied faceted indices |
| Strap | Black calfskin leather with polished stainless steel pin buckle. Leather is adequate quality but not luxury-grade. | Brown calfskin leather (or 5-link stainless steel bracelet on .14 reference variants) |

- Limited US distribution — difficult to try on in person outside major cities
Seiko Presage Cocktail Time
- Hardlex (not sapphire) — first thing many owners wish were different at this price
