Patek Philippe 5378 ($330k): Tourbillon-perpetual-calendar, Patek Seal. Liquid resale. Lower production = harder to source. Status piece.
F.P. Journe Tourbillon Souverain Vertical ($325k): Independent watchmaker, rose-gold-plated brass movement, constant force mechanism. Connoisseur signal. Lower brand recognition outside watch circles.
Greubel Forsey Tourbillon 24 Seconds ($380k): Inclined tourbillon (24-second rotation, 25° inclination). Ultra-low production (~50/yr). Highest movement-engineering content.
Patek for resale liquidity. Journe for connoisseur prestige. Greubel for outright engineering. None are wrong.
