When the Patek Philippe Nautilus originally debuted in 1976, collectors were scandalized at the high retail price for a stainless steel watch. The price was almost the same as similar 18k gold watches. Neither Patek nor its customers back then could have foreseen the success the Nautilus would achieve.

Case is 18k gold and stainless steel with dimensions of 40.6mm wide by 44.5mm long by 8mm thick. Sapphire crystal. Patek introduced the Nautilus as a sports watch to fill a void in their model line. The case is water resistant to 120 meters. The Nautilus bezel is a design icon. Full-length bracelet is integral to the case and has a flip lock safety clasp.

Dial is untouched and original, gold in color with horizontal channeling and sigmas on both sides of ‘SWISS’, applied golden hour markers with luminous, and the date at 3 o'clock. Original hands with luminous.

Movement is the automatic winding Patek Philippe Caliber 28 255C with 36 jewels, adjusted to 5 positions and heat/cold, and stamped with the Geneva Seal. The movement features a free-sprung balance and an 18k rotor segment for increased winding efficiency.

This is an important vintage Patek Philippe. Only approximately 600 original early thick bracelet 3700/1AJs were ever made.
