Royal Jewelers offers this extremely rare Patek Philippe Ref 1578 GM in excellent condition. According to a Christie’s auction note, GM commissioned a series of 20 watches for its top overseas employees, and these are the only 1578’s to leave the factory with a black dial. The 18K yellow gold case is 35 mm in diameter and the case back is engraved “GMC – GMOO/J.J McLaughlin/1936-1961.” The black dial has a nice patina, applied index and Arabic hour markers, and feuille hands indicating hours, minutes, and small seconds. The movement is Patek Philippe’s highest grade caliber 27AM-400, “amagnetic,” double stamped with Geneva Hallmark.
