A replica IW371673 is a copy of the IWC Portugieser Chronograph, a 41 mm steel watch with a vertical two-register dial and a slim, rounded case. A close copy matches the 41 mm size, the subdials at 12 and 6, the leaf hands, and the domed crystal. Copies that miss the case thickness or the subdial spacing read as fakes from across a table.
The 673 code sits inside the IW3716 family, where dial color, hands, and strap change from one reference to the next. Check which dial your chosen code carries before you buy. A copy built for the wrong dial color is a copy of a different watch.
IWC Portugieser Chronograph specs a replica IW371673 should match
- Case: 41 mm stainless steel, about 13 mm thick
- Lug width: 20 mm, with lugs that curve down toward the wrist
- Dial: two subdials, small seconds at 6 o'clock, chronograph counter at 12
- Crystal: domed sapphire with anti-reflective coating on both faces
- Movement: IWC calibre 69355, automatic, 46 hour power reserve
- Water resistance: 30 m (3 bar) on the genuine watch
These are the numbers IWC publishes for the IW3716 line. If a listing quotes a 44 mm case, a single subdial, or a 70 hour reserve, the seller is describing a different watch.
How to read a replica IW371673 listing
Dial and printing
Zoom in on the text at 12 o'clock. Clean copies print IWC and SCHAFFHAUSEN with even strokes and no bleed into the dial. The subdials should sit in recessed wells, each with its own printed track, not as flat discs glued on top.
Case and lugs
The lugs on this watch wrap the wrist, and that shape is hard to copy. Ask for a side profile photo. A slab-sided case with straight lugs and a thick bezel is a giveaway, no matter how good the dial looks.
Crystal
The real watch uses sapphire with coating on both faces, which kills most reflections. A copy that uses glass shows a blue or purple sheen and heavy glare under a light. Ask for a shot taken near a window.
Caseback
If the seller shows a display back, study the rotor and the bridges. Engraved text should be crisp and centered. Blank plates, sandy laser etching, and mismatched movement screws point to a budget build.
Movement options inside a replica IW371673
Three groups show up in the replica market, and the movement changes how the watch feels on the wrist.
- Quartz. Cheap, keeps time, and the chronograph sweeps in ticks. The pushers feel stiff and the seconds hand jumps.
- Asian automatic chronograph. A hand-wound or automatic movement with a visible column wheel and a smooth sweep. The pushers have a click you can feel.
- Decorated clone styled after the 69355. Engraved rotor, striped bridges, and a layout that survives a look through a display back.
Movement choice drives the price more than any other part. A quartz build costs a fraction of an automatic one, and the gap shows the moment you press a pusher.
How much does a replica IW371673 cost?
Replica prices track the movement, the dial work, and the case finish, so the range is wide. Budget quartz versions sit at the low end. Automatic copies with a decorated movement and a sapphire crystal sit at the top of the market.
Price alone does not sort the good from the bad. A mid-range automatic copy with a correct dial often beats a costly one built for the wrong reference code.
What no replica IW371673 matches
The case finish, the chronograph feel, and the movement are the three areas where copies fall short. A replica can print a dial and cut a steel case. It rarely matches the 46 hour reserve, the tolerances of a Swiss movement, or the service network behind the real watch.
Resale is the other gap. Genuine Portugieser Chronograph watches trade in the secondary market and hold part of their value. A copy sells for what the seller asks and nothing more.
FAQ about the replica IW371673
Is a replica IW371673 waterproof?
Assume not. The genuine watch is rated to 30 m, which covers splashes and rain, not swimming. Most copies use weaker gaskets, so keep them away from water even when a listing claims a rating.
Does the chronograph work on a replica IW371673?
On quartz and automatic copies, yes. The pushers start, stop, and reset the counter. Reset is the weak point on cheap builds, and forcing a stuck pusher can break the movement.
How close is the size?
Good copies land within a millimeter of the 41 mm case and the 20 mm lug width. Thickness is where they slip. A watch that sits 2 mm taller than the real one looks bulky under a shirt cuff.
Can a jeweler tell it is a copy?
A watchmaker who opens the caseback will know in seconds. From arm's length, a good copy passes. Under a loupe at a counter, it does not.
Checklist before you order a replica IW371673
- Confirm the dial color and hands for the exact reference code.
- Ask for photos of the case side, the dial text, and the caseback.
- Check the movement type and whether a display back shows it.
- Confirm the chronograph starts, stops, and resets to zero.
- Set your own expectations on water resistance and warranty.
A replica IW371673 is a look-alike, not a substitute. Buy it for the shape on your wrist, and check the details that decide the quality: the 41 mm case, the two subdials, the dial printing, and a working chronograph.
