The new IWC-manufactured 89630 calibre in the Da Vinci Perpetual Calendar Chronograph is the first from IWC to combine the double chronograph counter with Kurt Klaus’s moon phase system and place them both on a subdial.
If you were to approach the former fishing village of Portofino from the sea, the picturesque old houses could easily trick you into thinking that time had stood still, until you suddenly notice the sleek yachts with their luxury interiors and state-of-the-art technology lying at anchor. The elegant Portofino Chronograph provokes a similar reaction.
The chronograph’s technical features also represent a massive leap forward in the evolution of the IWC Aquatimer. The newly developed external/internal rotating bezel with a SafeDive system designed to prevent inadvertent changes of the dive time boosts the practical use of the diver’s watch, as does the increase in water-resistance from 12 to 30 bar.
