A fake IW3717 is a counterfeit or replica version of the IWC Portugieser Chronograph reference 3717. The fastest way to judge one is to compare the case profile, dial printing, subdial spacing, and movement finishing against verified photos and reference specifications.
Because the IW3717 designation is tied to a family of Portugieser chronographs rather than one unchanged watch, identification starts with the exact variant. Replica makers often blend features from different generations, and those mismatches are easier to spot than tiny finishing flaws.
What the IW3717 reference actually is
The IW3717 belongs to the IWC Portugieser Chronograph line. Across generations, the model has used different movements, case details, and dial variations. Before judging a watch as a fake IW3717, confirm which version it is supposed to represent.
- Model family: Portugieser Chronograph, a two-register chronograph with a clean, readable dial.
- Reference risk: Sellers sometimes use “IW3717” loosely for any Portugieser chronograph, which makes feature comparisons unreliable.
- Best comparison source: official reference specifications and sharp photos of known-original examples, not marketplace thumbnails.
Quick checklist: fake IW3717 warning signs
- Case proportions look too thick, too flat, or too wide for the reference being offered.
- Dial printing is uneven, too bold, or placed with inconsistent spacing.
- Subdial rings sit too close to the center or too far apart.
- Hands look flat, poorly polished, or the wrong length for the minute track.
- Caseback engraving is shallow, blurry, or arranged differently from known examples.
- The movement visible through the back looks unfinished or does not match the expected architecture.
- Papers, box, and warranty card look generic or carry mismatched reference details.
Case, lugs, and crystal
The case is where many IW3717 replicas reveal themselves. Original Portugieser chronographs have a specific profile, lug shape, and blend of brushed and polished surfaces. A copy may look correct from the front but feel wrong in the hand.

Look at the lugs from the side
Check whether the lugs curve naturally into the case and whether the spring bars sit cleanly. On a fake IW3717, lugs can look thick, sharply cut, or poorly finished underneath, where photos rarely focus.
Check the crystal and bezel edge
The sapphire crystal should sit with even height and no cloudy edge. The bezel should frame the dial without a wide, uneven gap. Reflections can hide flaws, so ask for angled photos in daylight.
Dial and subdial details
Dial flaws are often the easiest way to identify a replica IWC Portugieser. The Portugieser layout is simple, which means small errors stand out: font weight, track spacing, and the relationship between the hands and subdials.
- Printing: Look for fuzzy edges, thick numerals, or lettering that sits too close to the minute track.
- Subdials: The two registers should be balanced and spaced consistently with the reference.
- Hands: Leaf-style hands should have clean edges and a finish that matches the case metal.
- Markers: Applied markers should sit level, with no glue visible around the edges.
Movement and caseback
An open caseback makes movement inspection useful, but only if you know what the reference should contain. Replica sellers often describe a “clone” or “Swiss-style” movement without naming it. Ask for clear macro photos of the balance, rotor, and engraving.
On a fake IW3717, the movement may be a stock chronograph caliber with decorative plates or generic engraving. The finishing can look stamped rather than applied, and the rotor text may be shallow or misaligned. If the seller refuses movement photos, treat that as a warning.
Strap, clasp, and paperwork
Straps are easy to swap, so do not rely on leather quality alone. Check the buckle or deployant clasp for clean engraving and correct proportions. Paperwork matters more: reference numbers, serial details, and dates should agree across the warranty card, hang tag, and receipt.
- Box texture and interior layout should match the period of the watch.
- Warranty card printing should be sharp, with no smudged or mismatched numbers.
- Service papers should name the reference and describe work that fits the watch.
Price and seller red flags
A steel Portugieser chronograph has a established secondary-market range that depends on condition, age, box, and papers. If an IW3717 is priced far below comparable listings, the reason is usually not luck. Vague listings, pressure to pay off-platform, and “no returns” terms are common warning signs.
Ask for a video showing the chronograph starting, stopping, and resetting. Request a close-up of the caseback and movement. A seller who cannot provide those basics is not a safe source for a watch in this price class.
Legal and practical risks of buying a fake IW3717
Buying a counterfeit watch is not just a quality issue. Selling or importing counterfeit goods can violate trademark law, and customs authorities may seize shipments. Resale is difficult, service support is limited, and the watch may not hold value. If the goal is to enjoy the Portugieser look, compare openly sold homage or replica options with clear disclosures, and understand the legal limits in your country.
Bottom line
A fake IW3717 usually fails on proportion, dial precision, or movement details before it fails on anything dramatic. Confirm the exact reference, compare against official specifications and known-original photos, and demand clear images of the caseback, movement, and paperwork before you buy.
