If you are searching for a replica IW371476, the best path to that dial is a pre-owned genuine IWC Portugieser Chronograph ref. 3714 from a dealer who puts authenticity in writing. That is the top pick. Every option below is scored on four criteria: how closely the dial and case match the original, what movement sits inside, whether the watch can be serviced and resold, and the real cost of ownership over five years. The reference itself breaks down as IW3714 plus 76, which places it inside the 40.9 mm Portugieser Chronograph family rather than the newer 41 mm ref. 3716 line.

What makes this reference worth chasing

The 3714 family carries a dial layout that is hard to fake well and easy to spot when done badly. You get a clean two register face with chronograph minutes at 12 and running seconds at 6, leaf shaped hands, applied Arabic numerals, and a fine railroad minute track around the edge. The case measures 40.9 mm and holds calibre 79350, a 44 hour automatic built on the Valjoux 7750 base. Water resistance is rated at 30 m, which is enough for rain and hand washing and nothing more. The caseback is solid steel, a detail that matters later when you check authenticity.

Option 1: Pre-owned genuine ref. 3714 (top pick)

Buying the real thing used costs more up front than any counterfeit and less than most people assume. The 3714 has been in production for years, so supply is steady and prices sit well under new retail for earlier examples.

  • Pros: exact proportions, correct 79350 movement, full service support from IWC and independent watchmakers, a serial number that traces to a real watch, resale value that holds.
  • Cons: highest entry price of the four options, earlier examples may need a $500 to $900 service, solid caseback means you cannot inspect the movement at purchase.

Best for: buyers who want the actual object and plan to keep it more than three years.

Option 2: Unbranded homage chronographs

Several small brands sell Portugieser style chronographs with no trademarks on the dial. Design protection on a watch this old has largely lapsed, and a watch with no logo is not pretending to be an IWC.

  • Pros: a fraction of the cost, often Seiko or Miyota mechanical chronograph movements that any watchmaker can service, no legal exposure for the buyer.
  • Cons: case finishing rarely matches, subdial spacing is usually off, hands are thicker, and the watch has no resale market at all.

Best for: someone who likes the layout and wants to test whether a 41 mm dress chronograph suits their wrist before spending real money.

Option 3: Mainstream chronographs with a similar face

Longines Master Collection chronographs, Frederique Constant Classics chronographs, and Tissot Le Locle chronographs all deliver a two register dress chronograph on a leather strap in the same size band. None copies the Portugieser, but all sit in the same visual family.

  • Pros: full manufacturer warranty, authorized dealer support, strong resale for the Longines in particular, comparable case finishing.
  • Cons: different hand shape, different numeral font, so nobody will mistake it for the IWC.

Best for: buyers who want a dress chronograph they can wear daily and service at a mall jeweler.

Why counterfeit listings fail their owners

A counterfeit 3714 usually runs a low grade 7750 clone in a case that is two or three millimeters too thick. That extra depth is visible under a shirt cuff and obvious next to a real one. Customs can seize the shipment, no watchmaker will touch the movement for a repair, and the resale value is zero on the day you buy it. Sellers also rarely honor returns, so a dial defect or a dead chronograph hand becomes your problem.

Authentication checks when buying used

  1. Confirm the caseback is solid. A ref. 3714 with a display back is wrong.
  2. Read the reference and serial engravings on the caseback. They should be crisp and consistent with the paperwork.
  3. Check subdial spacing against a known original photo. Replicas push the registers outward.
  4. Measure thickness. Anything past roughly 14 mm on a 3714 deserves a question.
  5. Ask for service records and pay with a method that offers buyer protection.

Which one to pick

If the goal is the real dial on your wrist, save for the pre-owned 3714 and buy from a dealer with a written authenticity guarantee. If the goal is the look on a budget, choose an unbranded homage and accept the compromises. If the goal is a reliable dress chronograph with a warranty, the Longines Master Collection is the practical answer. Skip the counterfeit listings entirely: they cost more over five years than any of these, and they cannot be serviced, insured, or sold.
