Frederique Constant Highlife Automatic COSC
- Brand recognition below heritage Swiss brands — Longines (1832), Omega, Tudor have stronger name recognition. FC (1988 founding) is a younger brand without the same cultural footprint despite genuine horological credentials.
- 50m water resistance — limited dress-sport spec; not for serious water sports
- Sellita SW200-1 base at a $2,500–$5,000 band retail — fair value with COSC paperwork but some buyers expect in-house at this price tier
- 38-hour power reserve — modest vs. 70–80 hour Powermatic 80 / Tudor MT5402 / Longines L888 competition
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)
