Junghans Max Bill Chronoscope
- Valjoux 7750 base at a $1,500–$2,500 band price. Some buyers feel the base movement doesn't justify the retail price. The defense: you pay for the design heritage and German assembly, not the movement engineering.
- Acrylic crystal scratches. The SICRALAN coating helps but doesn't make it sapphire-equivalent. Buyers expecting absolute scratch resistance should choose a sapphire-crystal sibling reference.
- No lume. The Max Bill dial is intentionally lume-free — Bauhaus design principles take precedence over practical readability in the dark.
- 14.4mm thickness. The 7750-based Chronoscope is inevitably thick for what reads visually as a slim dress watch. The proportions feel less honest than the 38mm time-only Max Bill Automatic.
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)
