What is the difference between Patek 3700 and 3800?
A key differentiator for the Nautilus 3800 was its movement. Unlike the flagship 3700 model, which was powered by a movement from Jaeger LeCoultre, the 3800 featured Patek Philippe’s own in-house Caliber 335 SC. The Patek Philippe Nautilus reference 3800 was launched in 1981 and discontinued in 2006.
