The moon phase display is not just an aesthetic masterpiece – it also reminds us that, long before time could be mechanically measured, it was the moon that showed us the passing of time. The stainless-steel version of the Portofino Automatic Moon Phase 37 with a silver-plated dial comes with a dark brown alligator leather strap from the House of Santoni. The sun-pattern finish on the dial reflects light in a myriad of different ways and makes the light appear to move around in circles when the watch is tilted from side to side, lending the timepiece a unique charm. The slightly recessed inner circle as well as the 12 diamonds add a sense of structure to the dial. The timepiece is water-resistant to 3 bar and powered by the 35800-calibre mechanical automatic movement. The phase of the moon shown in the display can be adjusted using a correction button at “2 o’clock”. The central seconds hand is stopped using the crown and the sapphire glass has an antireflective coating on both sides.

IWC’s moon phase displays are not just aesthetic works of art – they are extremely precise and diverge from the actual phase of the moon by just 1 day in 577.5 years.
