Blue anniversary-style chronograph · ten-photo QC
IWC Schaffhausen Portugieser IW371601 Replica Watch
Ten photographs show a blue vertical two-register chronograph-style dial, bright steel-colour case, crown and two pushers, black glossy crocodile-pattern strap, deployant clasp and transparent-back automatic mechanical appearance. The record also includes about 43.8 mm across the crown-side envelope, about 13.6 mm thickness, 88 g and one timegrapher screen.
The sample follows the genuine colour and display-back direction, but the proof stops at appearance
IWC specifies a blue lacquer dial, steel case, black alligator strap, sapphire display back and calibre 69355. Similar colours, C.69355/27 JEWELS-style text and a transparent back do not prove the replica's alloy, strap species, crystal, installed movement or official limited-edition status.

A close visual direction with one finish question
Official Blue Lacquer vs. the Sample's Radial-Light Appearance
Official anniversary design
IWC identifies a blue lacquer-finish dial with rhodium-plated hands for genuine IW371601.
Sample photo appearance
The photographed blue face shows a pronounced radial light pattern that can read as sunburst-like under the current lighting.
Useful confirmation
Ask for diffuse neutral-light views at several slow angles before describing the replica dial finish as a match.
IWC Portugieser replica buyer guide
IW371601 Guide: Blue Dial, Display Back, Measurements & Chronograph QC
Blue is the defining front-view colour
The dial field is unmistakably blue in the straight-on photographs, while the applied-looking Arabic numerals, dot markers and leaf-style hands read as bright silver or rhodium-colour details. That combination is much closer to the genuine IW371601 colour direction than the silver-white faces on older 3714 references, but colour similarity is not material or identity proof.
The photographed surface shows a radial-light pattern
IWC describes the genuine anniversary watch as having a blue lacquer finish. In this sample, light appears to radiate across the dial in a sunburst-like pattern. Camera angle and strong illumination can create or exaggerate that effect, so final QC should include straight-on and slowly angled views under diffuse neutral light.
Vertical registers preserve the Portugieser chronograph layout
A counter sits at 12 and a small-seconds-style display sits at 6, with the central hands and large Arabic numerals leaving the face open. The outer scale adds the precise instrument-like frame associated with the collection. Still images establish arrangement, not the mechanical role or coupling of each hand.
The upper register needs a real accumulation test
The genuine watch's chronograph records minutes and seconds. For the replica, request one continuous sequence showing start, elapsed central seconds, visible upper-register advancement, stop and reset. Short clips or separate stills can hide a nonfunctional counter, slipping hand or imperfect zero return.
Small seconds and hacking require direct observation
IWC lists small hacking seconds for the genuine reference. The lower register's appearance does not prove whether it runs continuously or stops when the crown is pulled on this replica. Ask for a close, uninterrupted winding and setting demonstration that keeps the same back number in view.
Protective films obscure all three control ends
Blue films remain on the crown and both pushers. They can hide scratches, logos, polishing, colour mismatch or uneven edges. Film-free exact-unit photos should show each end straight on, each side of the case, and the gap and alignment around every control.
Steel colour is not an alloy certificate
The case, bezel, controls, back ring and clasp appear bright steel-colour, with polished and brushed-looking zones. IWC specifies stainless steel for the genuine watch. The photographs cannot identify the sample alloy, surface treatment or corrosion resistance, so those details belong in the written order record.
Black crocodile pattern broadly follows the genuine strap direction
IWC specifies a black alligator leather strap for the genuine IW371601. The photographed sample uses a black glossy crocodile-pattern strap with dark stitching and an IWC-style underside stamp. That supports a colour and texture comparison only; it does not prove leather species, tannery, official manufacture or origin.
The deployant clasp is visible but not yet a comfort test
Open-strap photographs show the folding clasp architecture and keepers. They do not show closed wrist range, edge comfort, release security or long-term wear. Ask for the smallest and largest practical circumference, clasp operation and close views with protective covers removed.
A transparent back is appropriate to the official design direction
Unlike older IW371445 and IW371446 genuine references with standard backs, IWC specifies a sapphire-display back for the genuine IW371601. The replica broadly follows that construction direction. A similar window does not prove sapphire, sealing, movement identity or genuine case architecture.
C.69355-style text is a matching label, not calibre proof
The photographed movement area carries C.69355-style wording, and IWC names calibre 69355 for the genuine reference. A label can be reproduced independently of the mechanism. Ask for the seller's exact movement designation, functional layout, service parts and repair route rather than equating engraving with construction.
Twenty-seven-jewel wording has the same evidence limit
The sample also shows TWENTY-SEVEN (27) JEWELS-style text, matching the genuine specification numerically. That is a useful delivery-continuity detail, but the photos cannot count functional jewels, establish their locations or confirm IWC manufacture. Treat the number as visible wording until independently verified.
Decoration should be judged as appearance
A rotor-style component, striped surfaces, circular textures, red jewel-like points and engraved-looking bridges are visible through the back. IWC lists Cotes de Geneve and perlage for the genuine movement. The sample can be assessed for visual neatness, but not assigned official finishing methods, 194 components or Swiss origin from photographs.
The 6233742-style number connects the later QC record
The back ring carries a 6233742-style string beside PORTUGIESER, CHRONOGRAPH and 3 BAR-style wording. Record that string through every final view and test so the front, back, measurements and instrument results stay attached to one watch. It is not proof of official serial validity or authenticity.
About 43.8 mm is a crown-side envelope reading
The caliper image reads about 43.8 mm with the control side included in the span. That is useful for estimating the watch's widest side profile, but it is not the same measurement as a crown-excluded case diameter. It should not be presented as the official case size or as a direct 2.8 mm mismatch.
Repeat the official-style diameter separately
IWC lists 41 mm for the genuine case. To compare like with like, request a second caliper view across the round case body away from crown and pushers, with the tool zeroed before placement and the jaws aligned across the true maximum diameter. Keep the 43.8 mm envelope as its own field.
About 13.6 mm is close to, but above, the official height
The side caliper photograph reads about 13.6 mm, roughly 0.5 mm above IWC's official 13.1 mm figure. The image does not demonstrate calibration or centred contact across the highest crystal and back points. Repeat it twice before using the reading for fit decisions.
Eighty-eight grams describes only the pictured setup
The scale displays about 88 g with the watch and strap resting on it. This provides a useful order-matching reference, but the zero state, calibration, film status and accessory condition are not shown. A final zeroed weight should use the exact delivered strap and clasp configuration.
The timegrapher screen is specific, but narrow
One display shows about -3 s/day, 259 degrees amplitude, 0.0 ms beat error and 28,800. These are more informative than an unsupported accuracy adjective. They remain a single position and moment with no stated lift angle, wind level, settling time or repeated trace.
Several-position timing is the useful next step
Ask for dial-up, dial-down and representative crown positions after a consistent full wind and settling interval. Record rate, amplitude and beat error in each position, then repeat near the end of the reserve. This reveals variation that a single attractive screen can miss.
A 46-hour genuine reserve is not a replica promise
IWC lists 46 hours for genuine calibre 69355. The sample set has no start-to-stop log. For this automatic replica watch, ask for the actual movement, a defined full-wind protocol, start time, periodic checkpoints and stop time tied to the 6233742-style number.
Three-bar wording is not a pressure result
The back ring carries 3 BAR-style text and the genuine watch has an official 3 bar rating. Neither fact tests the sample's gaskets, crown, pushers, crystal or caseback assembly. If water exposure matters, agree on a measured test and retain the exact-unit result; otherwise keep it away from water.
Crystal and anti-reflection remain unverified
IWC specifies a convex sapphire crystal with anti-reflective coating on both sides. The sample images show reflections but no material identification or coating test. Request the seller's written sample specification, neutral-light defect macros and clear warranty coverage rather than importing the genuine claim.
Limited-edition status belongs only to the genuine watch
IWC states that the steel IW371601 variant was limited to 2,000 pieces. Replica reference text and a case number do not place a sample in that genuine edition. The page uses the anniversary history to explain design context, not to imply official production, provenance or collectability.
Buyer keywords remain search language, not guarantees
The attached market sheet supports replica iwc watch, IWC Portugieser replica, chronograph replica watch, automatic replica watch, replica watches, luxury replica watch and high quality replica watch as relevant phrases. Some shoppers also compare super clone watches. None proves factory, grade, calibre, material, pressure resistance or authenticity.
The retained MP4 was not used as product evidence
The existing video remains embedded and accepted an HTTP Range request, but it was not watched. Every sample statement on this page comes from the ten reviewed photographs. Request a new continuous exact-unit record that joins the face, 6233742-style back number, controls, dimensions and functions.
IW371445 offers an older warm-tone route
The Portugieser IW371445 page keeps the classic vertical two-register layout but its reviewed sample uses a silver-white face, warm-tone details and a brown strap. Compare colour and back construction while keeping its measurements and evidence independent.
IW371446 is the older silver-blue comparison
The Portugieser IW371446 page pairs a silver-white face with blue details and strap. Its genuine reference belongs to the older solid-back 79350 generation, making the back and movement-style differences especially useful to compare.
IW371615 changes the later 3716 colour direction
The Portugieser IW371615 page is the next useful 3716-family comparison for buyers considering a green rather than blue face. Its own photos and measurements must be reviewed separately before transferring any detail.
Genuine-reference context was checked against IWC's official IW371601 past-collection page and the official Portugieser anniversary press release. Genuine specifications and replica photo evidence remain separate.
Exact genuine-reference context
Official IW371601 vs. This Replica Photo Record
IWC's genuine IW371601
IWC lists a 2,000-piece stainless-steel anniversary variant with blue lacquer dial, rhodium-plated hands, black alligator strap, sapphire display back, 41 mm diameter, 13.1 mm height, 20/18 mm strap/buckle widths, 3 bar, automatic calibre 69355, 46-hour reserve, 28,800 VPH, 194 components, 27 jewels, minute-and-second chronograph, small hacking seconds and convex double-sided anti-reflective sapphire.
This IW371601 replica photo set
The sample broadly follows the blue, steel-colour, black-strap and display-back direction. It shows 43.8 mm across a crown-side envelope, 13.6 mm thickness, 88 g and one timing screen, but does not prove official materials, dial finish, calibre, components, jewels, functions, reserve, crystal, pressure, edition status, provenance or authenticity.
Older warm, older silver-blue, or later green
Three Related IWC Models with Clear Reasons to Compare
Compare two older 3714-family colour routes or stay with the later 3716 architecture and change the dial direction.
Older warm-tone route
Portugieser IW371445
Its reviewed sample uses a silver-white face, warm-tone details and brown strap. The older genuine reference's solid-back specification makes the generation shift easy to see.
Older silver-and-blue route
Portugieser IW371446
Its silver-white face, blue details and dark-blue strap provide the strongest colour alternative, while its genuine solid-back 79350 context differs from IW371601.
Later green-dial route
Portugieser IW371615
This later 3716-family reference is the useful next stop when the buyer wants a green rather than blue face. Review its own product evidence independently.
How Time-mimic Should Handle an IW371601 Inquiry
The order record should preserve the photographed blue, steel-colour, black-strap and display-back configuration while treating movement text, official dimensions and anniversary history as separate evidence.
1 · Lock the visible configuration
Record blue face, bright details, steel-colour exterior, black patterned strap, display back and 6233742-style number.
2 · Repeat every measured field

Product, evidence and order questions
IWC Schaffhausen Portugieser IW371601 Replica Watch FAQ
What do the ten IW371601 photos confirm?
They show a blue vertical two-register chronograph-style dial, steel-colour case, crown and two pushers with blue protective films, black glossy crocodile-pattern strap, deployant clasp, transparent-back automatic mechanical appearance, a 6233742-style number, about 43.8 mm across the crown-side envelope, about 13.6 mm thickness, 88 g and one photographed timegrapher screen.
Is the sample dial finish proven to match IWC's blue lacquer specification?
No. IWC describes the genuine IW371601 as having a blue lacquer-finish dial. The sample photographs show a pronounced radial light pattern that can look sunburst-like. Lighting can change that appearance, so request neutral diffuse-light and angled macros before calling the finish a match.
Does the 43.8 mm photo conflict with IWC's official 41 mm diameter?
Not directly. The sample image appears to span the crown-side overall envelope, while IWC's 41 mm figure is the case diameter. The endpoints and methods are different. Ask for separate crown-excluded case diameter and crown-side overall-width measurements with zero and placement visible.
How should the 13.6 mm sample thickness be read?
It is a pictured single reading and is about 0.5 mm above IWC's official 13.1 mm genuine-watch height. The photo does not establish calibration, exact highest-point placement or repeatability, so treat it as sample evidence and request a centred repeat.
Does C.69355 and 27 JEWELS-style wording prove the replica movement?
No. Those labels correspond to genuine IW371601 specifications, but engraved text, decoration and rotor shape do not identify the mechanism underneath. Confirm the actual replica movement, functions, parts availability and service route in writing.
What does the timegrapher image establish?
It records one displayed moment of about -3 seconds per day, 259 degrees amplitude, 0.0 ms beat error and 28,800 in an unspecified position. It does not establish an average across positions, full-wind condition, lift angle, stability, reserve or future performance.
Are chronograph operation and a 46-hour reserve proven?
No. Still photos do not show one uninterrupted start-stop-minute-accumulation-stop-reset sequence, and there is no timed reserve log. Request several complete cycles and a recorded full-wind start-to-stop test on the exact unit.
Does 3 BAR-style back text prove water resistance?
No. The genuine reference is officially rated 3 bar, but the sample's engraving is not a pressure test. If water resistance matters, agree on an exact-unit test method, retain the result with the case number and follow the seller's care guidance.
Is this replica confirmed as one of the official 2,000-piece edition?
No. IWC limited the genuine steel IW371601 edition to 2,000 pieces. A replica's reference-style text, back number or visual resemblance does not provide official serial registration, provenance, authenticity or a place in that genuine production run.
How do I order this IWC Portugieser replica?
Record IW371601, the blue two-register dial, steel-colour exterior, black crocodile-pattern strap, display back, 6233742-style number and pictured measurements. Then request film-free macros, repeated sizing and weight, actual movement, full chronograph operation, several-position timing, timed reserve, crystal statement and any agreed pressure proof. The listed price is US$627 and a US$20 deposit starts sourcing and QC.
