Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
IWC Schaffhausen Da Vinci 43 mm Silvered Stainless sits within IWC Schaffhausen's Da Vinci line, introduced in 2014. It carries the house codes established since 1868 — stainless steel case, silvered opaline dial and in-house automatic, superlative chronometer — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
IWC Schaffhausen has spent more than 158 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Portugieser, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Florentine Ariosto Jones established IWC Schaffhausen in 1868, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every IWC Schaffhausen calibre produced today.
