The replica IW371432 is a copy of the IWC Portuguese Chronograph reference IW371432, a 40.9 mm stainless steel watch with a Valjoux-based chronograph movement, applied Arabic numerals, and a leather strap. Accurate replicas match the case diameter, the 20 mm lug width, and the sub-dial layout of the original. Budget copies usually miss the case thickness, the sub-dial spacing, and the crispness of the dial printing.
What specs define the IW371432?
The reference belongs to the IW3714 Portuguese Chronograph family, which IWC produced for roughly two decades before moving to the in-house 69355 caliber in the newer generation. Numbers to check on any replica:
- Case: stainless steel, 40.9 mm diameter, roughly 12.3 mm thick
- Lug width: 20 mm, curved lugs that hug the wrist
- Crystal: domed sapphire with anti-reflective coating on both faces
- Water resistance: 3 bar (30 m) on the original, so no swimming
- Movement: IWC caliber 79350, a reworked Valjoux 7750 with a 44-hour reserve
- Sub-dials: running seconds at 9, elapsed minutes at 12, elapsed hours at 6
- Dial: applied polished numerals, feuille hands, rail-track minute circle
Which movement sits inside a replica IW371432?
Almost every serious replica uses an Asia 7750, the Chinese clone of the Valjoux 7750 that the genuine 79350 is based on. That matters because the 7750 is what puts the running seconds at 9 and the counters at 12 and 6 in the right places. A quartz copy or any watch with sub-dials in the wrong spots is instantly wrong to anyone who knows the reference.
Higher tiers add engraved and decorated rotors, blued screws, and perlage finishing on the bridges. None of that changes how it runs, but it improves how the caseback looks when you open it.
How do you judge replica IW371432 quality?
Does the dial print look flat and sharp?
Genuine dials use pad printing that sits flush and stays legible under a loupe. Cheap replicas show thick, fuzzy text and misaligned minute tracks that drift off center.
Are the numerals polished and spaced correctly?
The applied Arabic numerals should catch light along their edges and sit evenly between the outer track and the sub-dials. Gaps that widen toward 3 or 9 are a common flaw on low-grade cases.
Does the case profile match the original?
Measure the thickness with calipers. Originals run near 12.3 mm, and copies that come in above 14 mm look tall on the wrist and sit oddly under a cuff.
Do the pushers and crown feel solid?
Chronograph pushers should click with a short, firm travel and reset the hands to zero every time. Mushy pushers or a hand that stops short of 12 point to a poorly assembled 7750.
What does a good replica IW371432 cost?
Quartz versions sell in the 80 to 150 dollar range, but they fail the sub-dial test and the sweep of the chronograph hand. Mechanical copies with an Asia 7750 typically land between 200 and 350 dollars. The top tier, with a better case finish, sapphire crystal, and a decorated movement, runs 350 to 500 dollars.
What should you know before buying?
A replica IW371432 is not authorized, warrantied, or serviced by IWC, and counterfeit sales carry legal risk in many countries. Independent watchmakers can service an Asia 7750, but parts availability varies and a full swap of the movement is sometimes cheaper than a repair. Treat the watch as a fashion item with a mechanical heart, not an investment.
FAQ
Is the replica IW371432 water resistant?
Assume no. Even when a seller lists 30 m, the gaskets on replicas are rarely tested, so keep it away from pools, showers, and dishwater.
Can I fit a genuine IWC strap?
Yes, if the lug width is a true 20 mm and the spring bars sit in the right position. Many owners upgrade to a leather strap with a steel pin buckle and skip the rest.
Does the chronograph actually work?
On an Asia 7750 it does, with a start, stop, and reset sequence identical to the original. Leave the chronograph running only when you need it, since it adds wear to the movement.
