DescriptionThe IWC Portofino Automatic Moon Phase 37 Ref. IW459009 is an exquisite embodiment of sophistication and horological innovation. The watch's case, crafted from 18 ct 5N gold, radiates a warmth and richness that is synonymous with luxury. This case, measuring 37.0 mm in diameter, strikes an ideal balance between prominence and elegance, making it suitable for a variety of occasions. Its height of 10.8 mm ensures a comfortable fit, highlighting IWC's attention to wearability and style. Complementing the lustrous gold case is the black alligator leather strap provided by Santoni, renowned for their exemplary craftsmanship. The strap's width of 18.0 mm is perfectly proportioned to the case, adding to the watch's cohesive and elegant design. Moreover, the timepiece offers practical water resistance of up to 3.0 bar, ensuring resilience alongside its stunning appearance.

This display diverges from the actual phase of the moon by merely one day in 577.5 years, illustrating the brand's dedication to accuracy in its most artistic form. Powering this magnificent timepiece is the 35800 Calibre automatic self-winding movement, a testament to the brand's expertise in watchmaking. This movement provides a substantial 50-hour power reserve, ensuring that the watch maintains consistent performance. Operating at a frequency of 28,800 vibrations per hour (VPH) and containing 25 jewels, it upholds the standard of precision for which IWC is known. The inclusion of central hacking seconds allows for precise time setting, an indispensable feature for those who value accuracy. Furthermore, the watch is fitted with a sapphire glass, convex and featuring an antireflective coating on both sides, ensuring optimal readability and durability.
