IWC Schaffhausen Da Vinci watches

The IWC Da Vinci takes its name from a watch of 1969: the first Da Vinci was IWC's first wristwatch with the Beta 21 quartz movement, a calibre IWC had helped to fund and develop. The name later passed to a family of complicated mechanical watches built around the Da Vinci Perpetual, a 39 mm perpetual calendar in yellow, white or red gold and in steel. The IW3755 is the same watch in black or white ceramic paired with yellow or white gold, and the IW3750-05 is a red-gold Perpetual limited to 120 pieces and named for IWC's 120 years.

Two higher complications sit beside it. The Da Vinci Perpetual Rattrapante adds a split-seconds chronograph, at 39 mm as the IW3751 and at 41.5 mm as the IW3754, with platinum versions limited to 500 pieces. The 39 mm Da Vinci Tourbillon (IW3752) adds a tourbillon; its Tourbillon Leonardo editions in yellow, white and rose gold were limited to 50 pieces each, and the yellow-gold Tourbillon Quattro Stagioni to 20. The Perpetual and Rattrapante came in English, French, German and Italian versions.

Simpler watches carry the name too: the 29 mm Kleine Da Vinci, and the 37 mm Da Vinci SL and SL Chronograph MecaQuartz in steel or yellow gold. Later models grew: the 43.1 and 44 mm Da Vinci Chronograph, including the ceramic IW3766, the 43.1 mm Perpetual Edition Kurt Klaus, named for the watchmaker behind IWC's perpetual calendar, and the 44 mm Perpetual Calendar Digital Date-Month. The 35.6 mm Automatic Midsize, the Da Vinci 36 Automatic and 36 Moonphase, the Da Vinci 40, the 43 mm Perpetual 3921 and the Chronograph Laureus, limited to 1,500 pieces, complete the family.

The crystal separates the generations at a glance: the Perpetual, Rattrapante, Tourbillon and Kleine Da Vinci have acrylic crystals, while the SL models and the later watches have sapphire.
