The Piaget Upstream (Ref. 27000) injects a bold, sport-luxury aesthetic into the brand’s historically dress-focused catalog. Rendered in striking 18K yellow gold, its 33mm by 40mm tonneau case delivers a commanding yet elegant wrist presence. The defining feature of this luxury timepiece is its revolutionary deployant clasp mechanism. Engineered directly into the watch’s bezel—a design feat that required 800 hours of rigorous development—it eliminates the traditional underside clasp for a seamless feel.
Beneath the clean dial, which features a swift sweep seconds hand and a date window positioned at 6 o’clock, runs the sophisticated in-house Caliber 504P automatic movement. Outfitted with 26 jewels, it operates smoothly at 21,600 vibrations per hour and holds a reliable 42-hour power reserve.
