The Patek Philippe reference 5016 is in the highest echelon of collector’s watches. Presenting minutes repetition, tourbillon and perpetual calendar in a classical platinum case, this is one of Patek Philippe’s most complicated and most sought after watches ever. Case is solid platinum with dimensions of 37mm diameter by 15mm deep. Sapphire crystals front and display back. Lugs are stepped and curve downward for comfort. Dial is silver in color, borderring on white. White gold stylized arabic numerals (also known as Breguet numerals) and pomme style hands. The moonphase is accurate to one day in 122 years. The minute repeater tone is extremely clear. This is Patek Philippe’s second most complicated wristwatch ever.
