Top pick: a 7750-based fake IW371466 with a vertical two-register dial, applied numerals, a domed sapphire crystal, and a seller who sends dated macro photos before payment. That build matches the dial layout, the case shape and the wrist presence of the genuine Portugieser Chronograph. The criteria below, meaning movement, dial print, subdial position, case thickness, crystal, caseback, strap and the seller's QC policy, decide whether the watch reads as a serious piece or as a giveaway.

What the IW371466 Actually Is
The reference belongs to the IWC Portugieser Chronograph family. The family signature is a slim bezel, a wide open dial, leaf-shaped hands, applied Arabic numerals, a railroad minute track, and two subdials stacked vertically at 12 and 6. The case sits near 41 mm across with a thin profile, and the movement is an in-house chronograph caliber in the 69355 range, an architecture that traces back to the Valjoux 7750. Before buying any replica, open the maker's own reference page for IW371466 and write down three things: dial color, case metal, and whether that exact reference carries a date window. Most fakes fail on one of those three points.

Criterion 1: Movement, 7750 Family Against Quartz
Almost every convincing fake of this reference runs a Chinese-made 7750 clone. That matters because the 7750 layout puts the subdials where the genuine watch puts them and drives a working chronograph with a reset that snaps back to zero.
Pros
- Correct subdial geometry at 12 and 6
- Sweeping seconds hand instead of a ticking one
- Pusher feel close to the original
- Serviceable by many independent watchmakers
Cons
- Thicker than the genuine caliber, so the case grows
- Rotor noise on cheaper examples
- Leaving the chronograph running adds wear
Best for: daily wear and anyone who wants the watch to feel mechanical in the hand. A quartz version suits a beater or a gift, not a side-by-side comparison.
Criterion 2: Dial Print, Numerals and Subdial Position
This is where cheap fakes fail first. Compare the following against reference photography taken at the same angle: the sunburst or lacquer finish across the dial, the raised numerals that should sit above the dial surface rather than print flush, the minute track thickness, the text under the 12 and above the 6, and the shape of the subdial hands.
Pros of a higher dial tier
- Applied numerals cast real shadows under light
- Text weight matches the genuine print
- Subdial rings sit at the correct depth
Cons
- Costs more than a printed-numeral build
- Demands closer inspection before you accept the watch
Walk away if: the subdials sit at 3 and 9, or a date window appears on a reference that has none.
Criterion 3: Case, Thickness and Bezel
The genuine watch is a slim chronograph, and the replica's main tell is bulk. Ask the seller to measure case diameter and thickness with calipers and send the photo. A 7750 build with a decorative plate often adds 1 to 2 mm over the original. Check the pushers at 2 and 4, the crown size, the lug curve, and the transition between brushed and polished surfaces on the case flank.
Pros: a well-finished case carries the watch on a bare wrist. Cons: thick cases sit high under a cuff and photograph badly from the side. Best for: buyers who wear short sleeves or want a conversation piece, since the profile is visible.
Criterion 4: Crystal and Coating
The genuine crystal is domed sapphire with anti-reflective coating on both faces. Look for a faint blue or purple glare and for a dark dial that stays readable at an angle. Flat mineral glass and uncoated sapphire show a mirror effect and wash out the dial.
Pros of coated domed sapphire: legibility, correct silhouette, scratch resistance. Cons: adds cost and is the first spec a budget seller hides. Best for: anyone who photographs the watch or wears it in bright daylight.
Criterion 5: Caseback, Engraving and Movement Finish
If your reference has a display back, the movement is on show and must hold up: striped bridges, blued screws, an engraved rotor and clean perlage on the plates. Engraving around the rim should be crisp and deep. Shallow stamping, wrong font or a serial placed in the wrong spot are easy checks before you pay.
Pros: good finishing survives a loupe. Cons: decorative plates hide a basic movement and can trap dirt. Best for: buyers who take the watch off in company or share photos of the back.
Criterion 6: Strap and Clasp
Alligator-embossed calf leather is the norm on this reference. Check stitch density, the taper toward the buckle, and the engraving on a folding clasp or tang buckle. A rattle in the clasp or soft stamping on the buckle is a fast tell. Budget for a replacement strap, since factory leather is the weakest part of most builds.
Criterion 7: Seller Photos and a QC Routine
Ask for a fixed set before shipment:
- Dated photos of the watch with a timestamp
- Dial macro in daylight, no filter
- Caseback macro with the engraving readable
- Side profile with calipers on the case
- Video of the chronograph start, stop and reset
- Lume shot if the reference has lume
Compare each photo with reference images of the genuine watch. Confirm the movement type in writing, and accept that no replica of this reference is pressure tested the way the genuine is, so keep it away from water.
Matching the Tier to Your Use
Desk wear and photos: a mid tier build with a printed-numeral dial and sapphire crystal covers most needs. Weekend and social wear: pay more for applied numerals, a domed coated crystal and a clean caseback. Travel or a knock-around watch: a quartz fake costs less and hurts less if it is lost, as long as you accept the wrong subdial character. Match the tier to how often the watch will be handled up close, because that is where the money shows.
