Nautilus chronograph sports watch series 5740

The Patek Philippe Nautilus 5740/1G-001, the brand's first Nautilus complication, pairs a 40mm case with a sophisticated calendar display: day and 24-hour at 9 o'clock, month and leap year at 3 o'clock, and date with moon-phase at 6 o'clock. Powered by a Caliber 240 automatic movement, this casual sports watch balances technical depth with everyday versatility for the discerning collector.
