Patek Philippe first introduced their moon phase complication in 1927; In 1977 they received a patent for their diminutive calibre 240 automatic movement, which would be placed in some of the greatest timepieces ever made, including this Patek Philippe Power Reserve Moon Phase 5015G, which was introduced in 1995.
