Editor's Notes

Powered by a calibre 89630 movement, IWC SCHAFFHAUSEN's 'Da Vinci' watch is the brand's first timepiece to combine a double chronograph counter with a moon phase complication on one subdial. It has been meticulously crafted in Switzerland from stainless steel and backed with sapphire glass to showcase the intricate workings of the mechanical movement. The perpetual calendar function is so precise that it will only need to be adjusted by one day after 577.5 years.

We offer an eight-year warranty for all working parts and manufacturing faults for IWC SCHAFFHAUSEN watches. For more information, contact one of our experts by emailing
