The PP Luxury Watches Nautilus Perpetual Calendar is designed in a 40mm 18k white gold case and smooth satin-finished octagonal bezel. The sporty blue dial hosts white-gold applied hour markers and three Perpetual Calendar sub-dials at 3, 6, and 9 o'clock, respectively. Complications include day, date, month, leap year, and 24-hour indication. Patek's thinnest Perpetual Calendar yet, this sporty and sleek timepiece settles nicely on the wrist. This particular model includes the iconic Tiffany & Co. branded dial settled just above the Moon Phase sub-dial.
