Frederique Constant Slimline Moonphase Manufacture
- 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 in-house horological credentials
- 42mm wears large for traditional dress watch — modern preference is often 38–40mm for dress; 42mm + slim bezel pushes visual presence larger
- 21mm lug width awkward for aftermarket strap fitment
- 30m WR limits to pure dress use — no swimming, no shower
Seiko Presage Cocktail Time
- Hardlex (not sapphire) — first thing many owners wish were different at this price
- 4R35 accuracy variance — unit-to-unit variation common
- Limited lume = none — intentional dress watch design but limits low-light use
- Leather strap quality is adequate — many owners upgrade
