IWCDa Vinci

The Da Vinci is IWC's collection for calendar complications, and the 1985 Perpetual Calendar by Kurt Klaus is the reason it matters. This library holds 270 references, with a rarity median of 8, the highest of any IWC line here.

About the IWC Da Vinci

The name first appeared in 1969 on a hexagonal watch carrying the Beta 21, the first Swiss quartz movement. Klaus's ref 3750 of 1985 reinvented it: a perpetual calendar chronograph on a Valjoux 7750 base, with a four-digit year display and every indication set from the crown alone, in a 39 mm case with articulated lugs. It made the perpetual calendar a production watch rather than a commission. The tonneau-cased Da Vincis of 2007 and the round 2017 relaunch followed.

The Klaus movement in its later form, the caliber 79261, is the most common here at 100 references, with the earlier 79251 in 42 more; together they are more than half the collection. The hand-wound 76061 appears in 32, the in-house 89360 chronograph of the 2007 tonneau in 17, and the 30130 in the automatic of the same generation. The 7750 family piece covers what Klaus built on it, and the glossary explains the perpetual calendar itself.

The 39 mm case of the 3750 accounts for 149 of the 270 references; the 43.1 mm tonneau for 25, and the 35.6 mm and 29 mm for the smaller models. Yellow gold is the most common material at 72, ahead of steel at 66, white gold, rose gold, platinum and red gold. 178 references have a plexiglass crystal, which dates most of the collection to before the 2000s. 66 are limited editions, and the tourbillon ref 3752 accounts for most of the 33 tourbillon references.

The Portugieser took over the perpetual calendar from 2003, and the Portofino the dress role.
