IWC Da Vinci Automatic Steel — Slate Dial | Ref. IW356602

Named for the Renaissance polymath whose notebooks anticipated centuries of engineering progress, the Da Vinci collection has always occupied IWC's most intellectually aspirational territory. The IW356602 distils that legacy into a 40.4 mm stainless steel case of exceptional slimness — 10.2 mm in height — that positions it as one of the thinnest automatic watches in IWC's current catalogue. The case architecture, with its distinctive curved lugs and polished-and-satin finishing contrast, references the design vocabulary established in the Da Vinci line's mid-1980s golden era while reading as unmistakably current.

The slate-coloured dial is among the most sophisticated chromatic choices in modern watchmaking — neither grey nor blue, but an intermediate tone with depth and complexity that shifts between cool and warm depending on the ambient light source. Applied indices and elegant leaf-shaped hands in polished steel provide the necessary contrast for legibility, while the date aperture at three o'clock integrates into the dial architecture without disrupting its proportional balance. Calibre 35111, a reliable automatic workhorse delivering approximately 42 hours of power reserve, keeps the case slim and the dial unencumbered.

A stainless steel bracelet with integrated clasp system completes the contemporary specification, providing the sportier alternative to the leather strap variants in the Da Vinci range. Convex sapphire crystal with antireflective coating on both faces and 3-bar water resistance establish the practical parameters of a watch equally suited to office and weekend wear. The IW356602 makes the case — quietly but persuasively — that the most refined watches are those in which every element, however subtle, is precisely considered.
