Patek Philippe Nautilus "Beyer", ref. 3800/001 from November 1984 A rare and highly collectible Patek Philippe Nautilus 3800 in steel and gold, designed by the legendary Gérald Genta. Measuring 37.5 mm, it features the signature blue dial with date display at 3 o’clock – but what makes this example stand out is the prestigious “Beyer” signature above 6 o’clock. Beyer Chronometrie in Zurich, one of the world’s oldest and most renowned watch retailers, has been a close partner of Patek Philippe since 1839. Double-signed dials from retailers such as Beyer, Tiffany & Co., and Gübelin carry special significance for collectors due to their exclusivity and rarity. Very few examples of the 3800 with Beyer signature have ever surfaced on the market. Inside beats Patek’s ultra-thin Caliber 335 S C – an automatic movement with central seconds, 29 jewels, a monometallic balance, and a solid gold rotor finished with classic Geneva stripes. A true demonstration of Patek Philippe’s horological mastery. This Patek Philippe Nautilus “Beyer” comes with boxes, paper and certificate.
