Welcome to my Top Swiss Chronographs Boutique: With its passion for innovation and technical inventiveness, IWC Schaffhausen has established an international reputation. Since 1868, manufacturers have been creating masterpieces of haute horlogerie. IWC mechanical timepieces are handcrafted with meticulous attention to detail, combine precision engineering with extraordinary timeless design, bringing finest technology and unique emotions to the wrist. To differentiate their mechanical offerings from the growing crowd of modernist quartz watches, IWC launched the Portofino line in 1984 as a “pocket watch for the wrist.” Designed to suggest a “marriage” watch, the Portofino features a thick, rounded case with a prominent crown, a plain dial with Roman numerals, and slim feuille hands. Although often compared to dress watches like the Patek Philippe Calatrava, the Portofino's Lepine “pocket watch” design is quite different. The first Portofino, 1984's Ref. 5251, used a classic hand-wound movement with small seconds at 09:00 o'clock. IWC released a classically-styled dress watch in the Portofino line in 1993, competing at last with the Calatrava.

Distributor's stock: the card isn't stamped. IWC black watch-box; it should be noted that this box model, in my opinion, is not perfect (I mean the black coating, it becomes a bit sticky over time, and nothing can be done about it). High recognition value. Distinctive design. Excellent condition, never worn: the wristwatch comes from luxury watch-shop showcase. My personal authenticity and quality warranty: you will get warranty card (as pictured), fully completed and signed on the back. Insured, registered shipping worldwide. What you see in my pics is what you get. In my opinion 'Le Petit Prince' is one of most remarkable chronographs in the gorgeous story of Swiss watchmaking, and not only dur to its lovely name.
