The closest legitimate stand-in for the IWC Portugieser Chronograph IW371494 is the Junghans Meister Chronoscope. It carries the traits that make the Portugieser easy to read across a room: a wide, uncluttered dial, a two-register chronograph layout, slim hands, and a case in the 40 mm range that slides under a shirt cuff. Every watch below was judged on four criteria: dial layout and legibility, case size and thickness, how it wears on a strap, and whether it comes from a brand you can buy through an authorized dealer with a real warranty and a service network.
One thing to settle first. Watches sold as a "fake IW371494" or a "1:1 replica" are counterfeit goods. They copy IWC's logo, dial text, and case shape, they cannot be serviced by the manufacturer, and they are illegal to import into the United States. If what you actually want is the Portugieser look on the wrist, the five watches here get you there without those problems.
1. Junghans Meister Chronoscope
Pros
- Two-register chronograph with the counters arranged on the vertical axis, the same reading rhythm as the Portugieser.
- Case size in the 40 mm range, close to the IWC reference, so the wrist presence is familiar.
- German brand with a long archive of dress chronographs, so the design does not look borrowed.
- Domed crystal and a thin bezel give it the vintage dress-watch profile you are chasing.
Cons
- The dial furniture and handset are distinctly Junghans, not IWC, so it is a cousin rather than a twin.
- Dress-watch water resistance, so keep it away from the pool and the gym.
- Dealer coverage in the US is thinner than the big Swiss names, which means fewer places to try one on.
Buy this if you want the closest overall match to the Portugieser silhouette and you care more about the dial than the badge.
2. Hamilton Intra-Matic Auto Chrono
Pros
- 40 mm bicompax case with a domed crystal and a racing-adjacent dial that photographs well.
- Panda and reverse panda dial options, plus blue variants, so you can dial in the look you want.
- Strong US service network and easy parts availability through Swatch Group.
- Available on leather or a bracelet, which changes the whole character of the watch.
Cons
- More sporty than the Portugieser, so it reads casual with a suit.
- Bicompax layout sits horizontally rather than vertically, which changes the face balance.
- Thicker case than a pure dress chronograph.
Buy this if you want the chronograph look with a broad service network and you split your time between office and weekend.
How to Get Fake IW371494: A Comprehensive Buying Guide
3. Seagull 1963 Chronograph
Pros
- Genuine military history behind the design, so it never feels like a copy of anything.
- Two-register layout with the counters at 3 and 9, thin bezel, and a compact case that suits smaller wrists.
- Manual-wind movement keeps the case thin and the dial close to the crystal.
- One of the lowest entry points into a mechanical chronograph.
Cons
- 38 mm case is noticeably smaller than the IWC reference.
- Acrylic crystal scratches and needs polishing.
- Red star and Chinese dial text are a different aesthetic from a Swiss dress chronograph.
Buy this if you want a thin, characterful manual chronograph and you are comfortable with a smaller case.
4. Baltic Bicompax
Pros
- Vintage-correct proportions with a slim bezel and stepped lugs that echo mid-century dress chronographs.
- Manual-wind bicompax movement, so the case stays thin on the wrist.
- Direct-to-buyer pricing keeps the spend well under a Swiss equivalent.
- Multiple dial finishes, including blue, so the color story can match the IW371494.
Cons
- Microbrand service means shipping the watch back rather than walking into a local shop.
- Case sizes run small by modern standards.
- Resale is limited compared with an established brand.
Buy this if you want vintage proportions and a blue dial without paying Swiss dress-chronograph money.
5. Longines Master Collection Chronograph
Pros
- Step up in finishing: applied indices, sunray dials, and a dress-first case profile.
- Blue dial options sit squarely in Portugieser territory for color and mood.
- Longines has a wide authorized dealer footprint and a deep service history in the US.
- Automatic movement with a respectable power reserve for daily wear.
Cons
- Costs meaningfully more than the other four picks.
- Several Master Collection references lean formal, so strap swaps matter.
- Dial text and layout follow Longines house style, not IWC.
Buy this if you want the most refined watch on the list and you plan to wear it as a dress piece.
What to check before you buy
- Measure your wrist and compare it with the case diameter and lug-to-lug distance, not just the number in the listing.
- Decide whether you want a vertical two-register layout or a horizontal one, because that dictates which of these watches looks right to you.
- Confirm the movement can be serviced locally. A counterfeiter's movement usually cannot.
- Check water resistance against how you actually live.
