Catalogue description

Dealer description — Bulang & Sons

IWC was founded in 1868 by American watchmaker Florentine Ariosto Jones in Schaffhausen, Switzerland, with the goal of combining American mass-production techniques with Swiss craftsmanship to create high-quality pocket watches. The company, now known as IWC Schaffhausen, is a renowned watch manufacturer that has expanded into wristwatches and innovative materials while remaining true to its engineering-focused philosophy. The IWC Portofino collection evolved from a design inspired by a classic pocket watch and has since become one of IWC's most successful lines, known for its understated elegance and timeless aesthetics. The full Portofino collection was officially launched in 1984, named after the picturesque Italian fishing village to evoke the spirit of la dolce vita . At hand, we have a Portofino in a 39 mm steel case with a blue soleil-finished dial, a date function, and rose-gold hour markers paired with leaf-style hands. Turning the watch over, you’ll find a striking “Khanjar” engraved on the case back. A khanjar is a traditional Omani ceremonial dagger with a curved, J-shaped blade. Worn by men as a symbol of status, masculinity, and national pride, it forms part of the traditional Omani dress for formal, religious, and celebratory occasions. Often ornately decorated, the khanjar is also the national emblem of Oman. This watch was gifted to someone special by the late Sultan Qaboos bin Said al Said. In the watch-collecting world, it is well known that the Sultan was an avid admirer of fine timepieces, and quite a number of Rolex, Cartier, and IWC models bearing this emblem are documented. This Portofino comes on its original IWC leather strap, fitted with a steel IWC pin buckle. The watch includes its original inner and outer boxes, with the outer box once again featuring a red Khanjar printed on top. It also comes with its original guarantee card and a “thank you” card in Arabic. The watch has been fully checked and regulated by our watchmaker.

Wristwatches

Bracelet watches were worn by women from the early nineteenth century — Breguet made one for Caroline Murat, Queen of Naples, in 1810–12 — but the wristwatch only became a man's instrument with military use and aviation in the early twentieth century. Between the World Wars it overtook the pocket watch; the 1920s and 1930s brought rectangular Art Deco cases, water-resistant cases and the first automatic winding systems.

After 1945 the wristwatch became a carrier of identity — dress watches, sports and dive watches, chronographs, calendars — produced by Swiss, American, Japanese, German, Soviet and Chinese industries. The quartz revolution after 1969 and the mechanical renaissance since the 1990s, including the rise of independent watchmakers, complete the story.

What to look for

  • The reference number (between the lugs or inside the case back) and serial number, the starting point for dating.
  • The calibre: its maker and number are often stamped under the dial or on the bridge.
  • Originality of dial, hands and crown — refinished ('redial') dials are common.
  • Case material marks: 18K/750, 14K/585, stainless steel, gold-filled, plated.

Dating clues

  • Wire-lug cases: before c. 1925.
  • Water-resistant screw-down cases: from 1926.
  • Quartz movements: from 1969; sapphire crystals widespread after c. 1980.
