IWC Schaffhausen
IWC Schaffhausen Portofino Automatic Moon Phase 37
To purchase please contact us
With its reduced case diameter of 37 millimetres, the Portofino Automatic 37 has become a staple in IWC’s watch portfolio, offering excellent wearing comfort on more slender wrists. The Portofino Automatic Moon Phase 37 features a stainless steel case, a silver-plated dial, and gold-plated hands and appliqués. On the dial, 12 diamonds mark the hours. For the IWC-manufactured 32800 calibre, IWC has integrated a moon phase module into a movement from the 32000 caliber family for the first time. The moon phase display at 12 o’clock works so precisely that it only deviated from the actual orbit of Earth’s satellite by one day after 122 years. A see-through sapphire glass back displays the movement, which has been finished with a gold-plated rotor and blued screws. This watch is fitted with a blue strap made of fully traceable Swiss calf leather. The strap has a natural and soft finish and boasts a contemporary, luxurious feel. Thanks to the integrated quick-change system, the strap can be exchanged easily.

Technical information about this watch
IWC Schaffhausen Portofino Automatic Moon Phase 37
![A water resistance icon in the shape of a shield. On the shield is a drop of water and beside the water are two lines that looks like waves.](http://ijl.ca/cdn/shop/files/IJL_WaterResistance_COLOUR_20x_crop_center.png?v=1701462277)
50M / 5 ATM water resistance
Water resistance indicates a watch's ability to withstand moisture and water. Ratings are measured in metres (M) or atmospheres (ATM). For instance, 30M (3 ATM) is suitable for light splashes, while 100M (10 ATM) and above are ideal for swimming and diving. Regular maintenance helps retain water resistance over time.

IWC Calibre 32800 Automatic movement
Watch movements are the mechanisms that power timekeeping, coming in automatic, manual, and quartz types. Automatic movements self-wind using wrist motion, manual movements require hand-winding, and quartz movements are battery-powered for precise timekeeping. Each type offers unique benefits, catering to different preferences and lifestyles.
![A watch case size icon that shows the head of the watch with an arrow on the dial giving an indication as to the diameter of the dial.](http://ijl.ca/cdn/shop/files/IJL_WatchCaseSize_COLOUR_20x_crop_center.png?v=1701462236)
37mm case size
Case size, measured in millimetres (mm), impacts the watch's look and fit. Men's watches typically range from 38mm to 46mm, and women's from 26mm to 36mm. Larger cases make a bold statement, while smaller cases offer a classic look. Choosing the right size ensures comfort and style.
![A power reserve icon that looks like a gauge that indicates how much power is left.](http://ijl.ca/cdn/shop/files/IJL_WatchPowerReserve_COLOUR_20x_crop_center.png?v=1701462256)
120 hours power reserve
Power reserve is the duration a watch runs on a full wind or charge. Mechanical watches usually offer 40 to 80 hours, with some extending to several days. Quartz watches, powered by batteries, last several years. Knowing the power reserve helps maintain accurate timekeeping.
