Refining the Essence of the Nautilus: To celebrate its 50th anniversary, Patek Philippe has released three limited-edition watches that highlight the classic elements of the Nautilus. All three Nautilus watches are time-only models (without a seconds hand or date display), featuring an ultra-thin case and powered by the iconic Caliber 240 micro-rotor movement, also born in the 1970s. This movement was introduced in 1977, a year after the Nautilus watch. The models are 5810G-001 (composite bracelet) and 5810/1G-001 (metal bracelet), both in 41mm white gold. The elegant 5610/1P-001 comes with a 38mm platinum bracelet. <p>replica Patek Philippe Grand Complications</p>
