Debut in 2004, the reference 5135 has enjoyed many variations until it was discontinued in 2011. The distinctive tonneau-shaped case was made in tribute to Patek Philippe's watches from the Art Deco period. Powered with calibre 324 automatic movement, the watch incorporates a patented annual calendar function that requires manual correction only once a year.
