In 2017 IWC returns to the round case that was successfully established by the Da Vinci Perpetual Calendar in 1985 and therefore says goodbye to the tonneau Da Vinci-case.
As a preview to the new Da Vinci collection that will be officially launched during the SIHH in January 2017, today I will start with the new IWC Schaffhausen Da Vinci Perpetual Calendar Chronograph
In the following days I will then show you the IWC Schaffhausen Da Vinci Automatic 36 and IWC Schaffhausen Da Vinci Automatic Moon Phase 36.
In these days IWC amazed the audience with a “perpetual” calendar & chronograph which required hardly any adjustments up to the year 2499 and was set using the crown only.
It no longer requires mentioning that the ingenious mechanism was developed by former master watchmaker Kurt Klaus.
And in keeping with the inventive tradition of the Da Vinci, IWC unveiled another first in 1986: the Da Vinci Perpetual Calendar (Ref. 3755) was the world’s first wristwatch to feature a case made of scratch-resistant and wear-free black zirconium oxide ceramic.

The moon phase is displayed by a disc, partly silver- or gold-plated, partly dark blue, which rotates to show the shadow of the earth and the waxing or waning moon below an aperture in the dial.
In order to achieve this, IWC’s watchmakers had to design the in-house 89630 calibre that powers the perpetual calendar’s other functions: the date, month, day and four-digit year display.
