IWC Schaffhausen New Portofino Automatic 37 Series with Manufacture 32000 Calibres and Sapphire Glass Backs

Swiss luxury watch brand IWC Schaffhausen unveils an enhanced collection of Portofino models with a case diameter of 37 millimetres. All of them feature movements from the IWC-manufactured 32000 calibre family with a power reserve of 5 days.

The Portofino Automatic Moon Phase 37 is available in three versions, while the classic Portofino Automatic 37 is presented in six new versions. As a first in the luxury watch industry, IWC offers straps made of fully traceable Swiss calf leather.

Each strap comes with a unique code that can be used to trace the source of the material online. Other references in the collection feature a newly developed high-grade 5-link metal bracelet.

The entire Portofino Automatic 37 collection is now equipped with IWC-manufactured movements from the 32000 calibre family, featuring an automatic pawl winding system and a power reserve of 5 days.

IWC watch case back

The movements have been elaborately finished with blued screws and gold-plated rotors and can be admired through sapphire glass case backs.

For the models featuring diamond-set bezels, the shape of the case has been optimised to accommodate larger stones of 1.7 millimetres. The dial and the case of these references are decorated with 72 diamonds totalling 1.12 carats. In addition, because of an improved setting, the diamonds reflect the light better and have a more visible presence and added brilliance. IWC has also applied a new type of sunray finish to the silver-plated dials, giving them a softer and even more refined appearance.

As a first in the luxury watch industry, IWC now offers straps made of fully traceable Swiss calf leather with butterfly folding clasps. These straps have a natural and soft finish and boast a contemporary, luxurious look. Each strap comes with a unique code which can be entered in the IWC app to find out more about the source of the leather.

Other references in the collection feature a newly developed high-grade 5-link stainless steel bracelet with polished and satin-finished surfaces. This sophisticated bracelet with a modern design is highly comfortable to wear. All models feature a quick-change system, making it possible to change the strap or bracelet using a small tool supplied with every timepiece.

IWC Portofino Automatic Moon Phase 37

For the Portofino Automatic Moon Phase 37, IWC has integrated a moon phase module into a movement from the IWC-manufactured 32000 caliber family for the first time. Thanks to a special reduction wheel train, the display works so precisely that it only deviates from the actual orbit of Earth’s satellite by one day after 122 years.

The moon phase disc, located at 12 o’clock on the dial, is made of solid gold and pad-printed with a blue night sky. The display can be adjusted easily in daily intervals using the crown.
