The IWC Da Vinci changed identity several times between its 1969 debut and the 2017 collection: it began as an angular gold watch with a Beta 21 quartz movement, became best known for Kurt Klaus’s crown-set perpetual calendar, and later served as a platform for ceramic cases and new chronograph complications. In 2017, IWC returned the family to a round case.
What is the history of the IWC Da Vinci?
The Da Vinci is not one fixed design or complication. Its history is a sequence of distinct ideas: electronic timekeeping in 1969, a user-friendly mechanical perpetual calendar in 1985, ceramic engineering in 1986, an in-house chronograph in 2007, and a renewed focus on round-case styling in 2017. The milestones below are drawn primarily from IWC’s own historical and press accounts, so priority claims and performance figures are attributed to the company.
1969: Beta 21 in a hexagonal gold case
IWC dates the first Da Vinci, reference 3501, to 1969. It paired the Swiss Beta 21 quartz movement with a distinctive hexagonal gold case. IWC describes it as the brand’s first wristwatch featuring Beta 21; that claim should not be broadened into a claim that it was the world’s first quartz watch. IWC’s Da Vinci history presents the watch as an early fusion of new electronic timekeeping and unusual precious-metal design.
1985: Kurt Klaus’s perpetual calendar
The defining mechanical milestone arrived with the Da Vinci Perpetual Calendar, reference 3750, developed by IWC watchmaker Kurt Klaus. Introduced in 1985 during the quartz crisis, it combined a mechanical chronograph with a perpetual calendar showing the date, day, month, moon phase, and four-digit year. IWC says those calendar indications were synchronized and could be adjusted together using the crown, making correction more straightforward than a system requiring separate adjustment of each display. The company also recounts that Klaus completed a working prototype just in time for the Basel Watch Show. IWC’s account of the perpetual calendar describes its development and operation.

IWC says the moon-phase display deviates by one day only after 122 years. That is the company’s stated performance figure, not an independently established measurement here. IWC’s two accounts give conflicting component totals for the calendar module—81 in one and 82 in the other—so no single count can be treated as settled.
1986: a ceramic-case first, according to IWC
The Da Vinci Perpetual Calendar reference 3755 followed in 1986 with a black zirconium-oxide ceramic case. IWC calls it the world’s first wristwatch with a scratch-resistant ceramic case. The company explains that ceramic shrinks by about one third during sintering, a manufacturing challenge that had to be accounted for to achieve tight tolerances. Both the priority claim and shrinkage figure are IWC’s account of the watch and its production.
2007: an entirely in-house chronograph movement
IWC revamped the collection in 2007 with the Da Vinci Chronograph, reference 3764, powered by calibre 89630. The company identifies it as IWC’s first entirely in-house chronograph movement. One of its practical display choices was to show elapsed hours and minutes together on a single subdial. IWC also describes reference 376601 as a ceramic-and-titanium variant.
2009: digital-style date and month
The Da Vinci Perpetual Calendar Digital Date, reference 3761, used large numerals to display the date and month. IWC connects the design to the brand’s nineteenth-century Pallweber pocket watches, whose displays used numerals in a digital-like fashion. That is the company’s interpretation of the design lineage; the Da Vinci itself remained a mechanical perpetual calendar rather than an electronic digital watch.

In a press release dated 15 January 2017, IWC announced a Da Vinci collection built around a return to the classically round case associated with the 1985 perpetual calendar. The lineup included Da Vinci Automatic and Automatic 36 models, a 36 mm Automatic Moon Phase, a Perpetual Calendar Chronograph, and a Tourbillon Rétrograde Chronograph. IWC described the Automatic as a 40 mm model and said the moving lugs were designed to help the watch sit on the wrist. The announcement marks a styling shift away from the tonneau form; it does not establish present-day availability. IWC’s 2017 collection announcement lists the models and references.
What makes the IWC Da Vinci Perpetual Calendar special?
Its significance lies in how it presented a complex calendar, not simply in the number of indications. The 1985 reference 3750 combined the perpetual calendar with a chronograph, while synchronizing the calendar displays so the owner could set them together through the crown, according to IWC. This made an elaborate mechanical complication more approachable to adjust. Its moon-phase precision is also notable in IWC’s telling: the company states that the display requires a one-day correction only after 122 years.
How the Da Vinci’s design and complications changed
The family’s shifts are clearest when its major versions are compared by case, timekeeping, complication, and styling. These are historical distinctions, not a guide to what is currently sold.
| Milestone | Case and design | Movement or timekeeping | Notable complication or feature |
|---|---|---|---|
| 1969, Ref. 3501 | Hexagonal gold case | Swiss Beta 21 quartz | First Da Vinci; IWC calls it the brand’s first wristwatch featuring Beta 21 |
| 1985, Ref. 3750 | Round-case perpetual calendar design | Mechanical | Chronograph and synchronized perpetual-calendar displays set together by crown, according to IWC |
| 1986, Ref. 3755 | Black zirconium-oxide ceramic case | Mechanical perpetual calendar | IWC calls it the world’s first wristwatch with a scratch-resistant ceramic case |
| 2007, Ref. 3764 | Da Vinci Chronograph design; ceramic-and-titanium variant also described by IWC | Calibre 89630; IWC’s first entirely in-house chronograph movement | Elapsed hours and minutes displayed together on one subdial |
| 2009, Ref. 3761 | Large date and month numerals | Mechanical perpetual calendar | Digital-style calendar display linked by IWC to Pallweber pocket-watch tradition |
| 2017 collection | Return to round cases; moving lugs; 36 mm models among the lineup | Automatic models and more elaborate mechanical complications | Included a perpetual calendar chronograph and tourbillon retrograde chronograph |
Why the 2017 return to a round case mattered
The 2017 redesign was a deliberate change in the family’s visual direction. IWC framed the round case as a return to the shape established by the 1985 perpetual calendar, while moving away from the tonneau form used in intervening designs. Its lineup also broadened the range of proportions and complications, from 36 mm models to the tourbillon retrograde chronograph. The moving lugs addressed fit as part of that redesign. IWC’s announcement was published in German; these details summarize its release rather than quoting a translated statement.
