Advertised as possibly the most expensive steel watch on the market back in 1976, PatekPhilippe ‘s first Nautilus reference 3700 remains as popular today. Pictured here is an astonishing piece of Nautilus 'Jumbo' Ref. 3700, preserved in very attractive condition with sharpness to the case, and boasting a beautiful tropical dial. With age, the black-blue ribbed dial has developed an incredibly eye catching patina radiating from the centre providing the watch with unique character. Offered as Lot 2209 with an estimate of HK$650k – 950k/ US$84k – 123k in our Hong Kong “Important Watches” Spring sale on 11 Jul.
