Short answer: a top tier replica IW371743 matches the genuine on case proportions, dial layout and wrist presence, and trails it on movement finish, pusher feel and long term timekeeping. Compared to a budget copy, the step up in dial printing and subdial depth is the difference you notice in the first ten seconds. Buy the better dial first and everything else second.
Replica IW371743 compared to the real watch: the honest gap
The IW371743 sits inside the Portugieser Chronograph family, so a replica is judged on the same points a collector checks on the original: the slim bezel, applied numerals, railroad style minute track and the vertical subdial stack at 12 and 6. Most replicas get the layout right. Fewer get the printing weight, the date aperture cut and the crystal clarity right.

- Case finishing: the good versions polish and brush the same surfaces as the genuine; cheap ones soften the lug edges and thin the bezel.
- Dial: printing weight, subdial recess depth and numeral applique shape are where the money shows.
- Crystal: double anti reflective sapphire is normal on the upper tier, single coating or mineral glass on the bottom tier.
- Movement: a decorated Asian chronograph calibre versus the Valjoux based movement used in the 3717 generation. Close in looks, different at the pushers.
- Strap: embossed calf leather versus genuine alligator, and the buckle engraving depth differs too.
Our first pick: the top tier replica IW371743
Start here. The upper tier version is the only one that holds up next to the genuine on a table, because the subdial spacing, the dial curvature and the crown profile are all copied from a scanned case rather than a photo. Expect a 40.9 mm case, roughly 12.5 mm thick, sapphire on both sides where offered, and a running seconds hand that sweeps without stutter. This is the version to compare against the real watch before you consider anything cheaper.
- Correct subdial position and recess depth
- Proper polishing contrast on the lugs and bezel
- Chronograph pushers with a firm, short travel
- Deployant or pin buckle with clean engraving
Option 2: the mid tier version
The mid tier gets the case and dial right and saves money on the strap, the crystal coating and the movement decoration. Compared to the first pick, the difference shows up in the subdial printing under a loupe and in a slightly louder rotor. On the wrist, most people will not separate the two. If the watch is a daily wearer and not a shelf piece, this is the value pick.
Option 3: the budget copy
Cheap replicas of the IW371743 usually fail on three things: thick bezel, flat subdials, and a date window that sits too proud of the dial. The chronograph may also be a decorative module rather than a working one. Buy this only as a novelty, and only if you accept that it will not survive a side by side comparison with the genuine.
Option 4: the modified or super clone route
The modified route swaps in a better base movement and a re printed dial, which pushes the price toward the top tier but can deliver the closest visual match of all. Ask for photos of the dial macro, the caseback engraving and the movement under daylight before paying. Sellers who cannot supply those three shots are not selling a modified build.
How to check a replica IW371743 before you pay
- Request a macro photo of the dial at 12 and 6 to judge printing weight.
- Ask for the case thickness measurement, not the listing claim.
- Confirm the chronograph actually resets to zero on both subdials.
- Check the date flips cleanly at midnight, not gradually.
- Compare the lug curvature to an official product photo of the reference.
Replica compared to genuine on cost and ownership
The genuine is a serviceable mechanical chronograph with factory support, resale value and a warranty. A replica has none of those. What a replica gives you is the look and the proportions for a fraction of the outlay, which is why the comparison matters more than the price tag. Decide which of those two experiences you actually want before you shop, and the choice between the four options above becomes simple.
