The reference 3450 was introduced as an upgrade in movement from its predecessor, the reference 3448, as despite their similar designs, the leap year indicator was absent from the 3448. Introduced in 1981, the reference 3450 was the very first perpetual calendar wristwatch to indicate leap years. The present 3450 maintains a vintage appearance and beauty. Like the majority of 3450 pieces, the watch features a yellow gold case that contrasts smoothly with yellow gold hour markers. A plain silvered dial provides a vivid display of a moon phase and perpetual calendar function, with a small leap year aperture between three and four o'clock. The perpetual calendar complication has been a favourite of Patek timepieces, dating back to a 1925 wristwatch as the earliest to feature the perpetual calendar.
