Welcome to my Top Swiss Chronometers 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.

Full set. Chic white IWC watch box (see pics). Excellent condition, never worn: the wristwatch comes from luxury watch-shop showcase; every morning the watch was put on the stand in the shop window, every evening it was removed from the window. I added brand new strap although the watch was not worn even with the original one: personally, I prefer brown straps with pink gold watches; this is where we disagree at IWC. The choice is yours, both straps are at your disposal. My pics are made with both straps, as you can see. General professional pre-sale service was made in September 2025: the watch is keeping good time and working perfectly. My personal authenticity and quality warranty: you will get warranty card (as pictured), fully completed, stamped and signed. Insured, registered shipping worldwide with DHL Express: it’s not cheap, and yet fast and reliable, two days in Europe, three days worldwide. Everything you see in my pics is included in the package that you'll receive. NO EXTRA COSTS for EU Buyers!
