The fake iw371770 is a replica of the IWC Portugieser Chronograph, one of the most copied dress chronographs in the world. This guide answers the questions buyers ask most: which details separate a convincing build from a cheap one, what the movement and case specs should look like, and what to expect when the package arrives. If you want the Portugieser look on a real-world budget, start here.
Key Features
- 41 mm stainless steel case with a polished bezel and brushed case flanks
- Bicompax chronograph layout: 30-minute counter at 12 and running seconds at 6
- Thin feuille hands, applied indices, and a fine railway-style minutes track
- Domed sapphire crystal with anti-reflective coating, plus a display caseback
- Automatic chronograph movement with roughly a 46-hour power reserve
- Rotor, bridges, and column-wheel style finishing visible through the back
- Alligator-grain or calf leather strap with a signed tang buckle
- Screw-down caseback and crown gaskets for everyday splash resistance
Materials and Specs
A good example copies the genuine proportions closely: about 41 mm across, roughly 13 mm thick, and 20 mm at the lugs, which is what makes the watch sit flat under a cuff. The case should be 316L stainless steel with crisp edges and no tool marks around the lugs. Dial printing is the tell — look for sharp, level text, evenly spaced subdial rings, and hands that reach the printed track. Mid-tier builds use a Seiko or Miyota-based automatic chronograph, while higher-tier builds use a column-wheel clone with smoother pusher feel. Crystal should be sapphire rather than mineral, and the strap should be stitched leather, not bonded synthetic.
Shipping and Returns
Orders typically ship within a few business days and arrive in discreet, plain packaging with tracking. Most sellers offer a short inspection window — usually 7 to 14 days from delivery — so open the box, check the dial alignment, run the chronograph, and confirm the crystal is clean. If something is wrong, a return or a replacement should be straightforward, so keep the packaging until you are satisfied.
Is the fake iw371770 worth buying?
Yes, if you want the Portugieser silhouette and a working chronograph without paying genuine watch money. Skip the cheapest listings; the extra cost at the mid tier buys a real automatic movement and a dial that holds up under close inspection.
How close is it to the genuine reference?
Externally it is very close on the wrist. The honest differences are inside — finishing under the rotor, engraving depth, and pusher feel — which is why display-back quality is the main thing to compare.
Which dial version should you pick?
Blue and silver-white dials are the safest, most versatile choices and the easiest to source well. Black is a good pick if you wear the watch with darker straps and want the subdials to read as one continuous surface.
