Portugieser Chronograph direction · ten-photo QC
IWC Schaffhausen Portugieser IW371445 Replica Watch
Ten photographs show a silver-white vertical-register chronograph-style dial, warm-tone Arabic numerals and leaf-style hands, steel-colour case, two pushers, brown glossy crocodile-pattern strap, deployant clasp and a decorated exhibition-back automatic mechanical appearance. The record also includes about 43.7 mm across the crown side, about 86 g and one timegrapher screen.
The genuine reference has a black strap and standard solid back
IWC lists a black alligator strap and standard caseback for the genuine IW371445. This replica sample is visibly different: its strap is brown and crocodile-patterned, and its back is transparent. The displayed movement and engravings do not prove calibre 79350 or genuine specifications.

Reference mismatch at a glance
Brown Strap, Display Back and Calibre-Style Engravings
Brown sample strap
The genuine IW371445 is officially specified with a black alligator strap. The photographed replica uses a brown crocodile-pattern strap.
Transparent sample back
IWC lists a standard solid back. This sample has a display back, making the rear design visibly different from the genuine reference.
Decorated automatic appearance
Rotor and bridge engravings can be matched visually, but they do not establish calibre 79350, component count, jewels, origin or manufacture.
IWC Portugieser replica buyer guide
IW371445 Guide: Dial Architecture, Reference Mismatch, Timing & QC
A classic vertical-register Portugieser layout
The silver-white dial uses large Arabic numerals, a fine peripheral scale, two recessed-looking registers at 12 and 6 and slim leaf-style central hands. Warm-tone numerals and hands soften the otherwise steel-colour exterior. This is the defining visual reason to consider an IWC Portugieser replica, but the exact unit still needs straight-on macro photographs for spacing, printing, hand finish and register alignment.
The upper and lower registers have different jobs
The genuine IW371445 uses the upper subdial for stopped minutes and the lower one for running small seconds. The photographed sample follows that visual architecture, but a still frame cannot establish what each hand actually does. Final QC should show normal running, chronograph start, minute accumulation, stop and clean zero reset without cutting away from the dial.
The thin central hand needs a reset test
A slender dark central hand sits over the dial. Its shape and position support a chronograph-style presentation; they do not prove engagement, smooth running or exact return to 12. Ask for multiple start-stop-reset cycles and inspect whether the hand jumps on start, drifts while stopped or settles off the zero marker.
Crown and pushers still carry blue protective film
The right profile shows a fluted crown between two pushers, with blue film on the control ends. Film can hide scratches, finishing transitions and edge quality. The final exact-unit record should remove it, show the controls under neutral light, then demonstrate winding, setting, hacking if offered, and chronograph operation in one continuous sequence.
Steel colour describes appearance, not metallurgy
The bezel, case, crown, pushers, back ring and clasp have a bright steel-colour appearance with polished and brushed-looking areas. IWC specifies stainless steel for the genuine reference, but visual colour alone cannot identify the sample's alloy. Ask for its actual case and clasp material, surface treatment, expected wear and warranty coverage in writing.
The brown strap is an obvious departure from the official black strap
IWC's historical page lists a black alligator leather strap for the genuine IW371445. The replica photos show a glossy medium-brown crocodile-pattern surface and dark underside. This can be an intentional styling choice, but it must be described as the photographed configuration rather than silently presented as a faithful match to the official accessory.
Strap stamps are not a supply-chain certificate
The underside carries IWC, MADE IN ITALY and DANG-style impressions. They are useful for matching the delivered sample to the photos. They do not prove country of manufacture, species, tannery, supplier, authenticity or official IWC origin. Confirm actual material, lining, wrist range, taper and replacement terms before paying the balance.
The deployant clasp changes fit and should be shown closed
A steel-colour folding clasp is photographed from the front and underside, with protective film still present. The mechanism appears articulated, but the images do not show a secure closed position on wrist. Ask for the clasp fully closed from both sides, a release demonstration and the smallest and largest comfortable circumference on the final strap.
The exhibition back is a major reference mismatch
IWC lists a standard solid back for the genuine IW371445. This replica sample instead shows a transparent back with a decorated automatic mechanical appearance and full-size rotor. That difference should be visible near the top of the page because it changes the watch's rear design and means genuine-caseback information cannot simply be copied across.
Movement decoration is not a calibre identity card
The back reveals bridges, red jewel-like points, a rotor and IWC SCHAFFHAUSEN and MADE IN SWITZERLAND-style wording. None of those visual details proves calibre 79350, 272 components, 31 working jewels, Swiss origin, manufacture or parts compatibility. Request the actual replica movement name, service route and spare-parts position separately.
The 6230401-style number must follow the exact unit
The back ring includes a 6230401-style number beside PORTUGIESER, CHRONOGRAPH and 3 BAR-style text. Record that visible string for QC continuity. It is not proof of a valid serial, official production or authenticity; its value is linking the same photographed case to later measurements and tests.
Blue-violet light is an inspection view, not a lab test
One image shines a blue-violet source across the display back. It may make dust, fingerprints, coating response or jewel-like elements easier to see, but the wavelength and method are not documented. It cannot establish sapphire, rubies, lubricant, luminous material, metal, coating or movement origin.
About 43.7 mm is a control-side envelope
The caliper reads roughly 43.7 mm and appears to span the crown side. That is a useful estimate of the watch's maximum horizontal footprint, not a crown-excluded case diameter. Ask for a repeat with the crown outside the jaws, both contacts visible and the display shown before and after placement.
Official 40.9 mm and pictured 43.7 mm use different endpoints
IWC states a 40.9 mm diameter for the genuine reference. Subtracting that number from the sample's wider control-side span would imply false precision. A fair comparison requires the replica's main case body to be measured independently, square to the case and clear of crown and pushers.
No sample thickness is shown
The side profile gives a useful visual impression, yet none of the ten photos puts the case between caliper jaws from the highest crystal point to the back. IWC's current historical page states 12.5 mm for the genuine watch. That number is background only until the exact replica receives a centred, zero-verified measurement.
About 86 g is one open-strap reading
The watch and open clasp rest on a scale that reads about 86 g. The photo does not document zero, calibration or removal of all protective film. A final reading should place only the exact watch, final strap and clasp on a zeroed platform and connect it to the 6230401-style back number.
The timegrapher result is useful but narrow
One screen shows about -4 seconds per day, 258 degrees of amplitude, 0.3 milliseconds of beat error and 28,800. Those numbers describe a single captured position and state of wind. They do not guarantee long-run accuracy, dial-up versus crown positions, performance with the chronograph engaged or service condition.
Matching 28,800 does not prove calibre 79350
IWC lists 28,800 VPH for the genuine 79350, and the sample instrument also displays 28,800. Frequency is shared by many movements and cannot identify architecture, component count or origin. The seller should name the actual replica movement and document how it is serviced instead of relying on one matching number.
The 44-hour official reserve still needs a sample test
IWC specifies 44 hours of power reserve for the genuine reference. The photo set contains no elapsed start-to-stop record. Agree on the winding procedure, start time, periodic checkpoints and stop time for the exact unit, ideally with the chronograph both disengaged and, if relevant to the buyer, briefly tested under load.
3 BAR text is not a pressure result
The display-back ring carries a 3 BAR-style engraving, and IWC gives the genuine model a 3 bar rating. Neither fact demonstrates the replica's seals or assembly. If water resistance matters, agree on the test method and limit, retain the result with the back number and treat the watch cautiously when no measured result is supplied.
Crystal claims need more than reflections
IWC specifies a convex sapphire crystal with anti-reflective treatment on both sides for the genuine watch. The sample photos show reflections but no material test, coating inspection or seller statement. Ask what crystal is actually fitted, what defects are covered and whether coating marks are included in warranty handling.
Search terms describe shopping intent, not verified quality
The attached workbook supports replica iwc watch, IWC Portugieser replica, chronograph replica watch, automatic replica watch, replica watches, luxury replica watch and high quality replica watch as natural phrases. Some buyers also search for super clone watches. None of these terms certifies factory, grade, material, movement, accuracy, water resistance or authenticity.
The retained video is not evidence for this page copy
The existing MP4 remains embedded and its server accepted a Range request. It was not watched. All sample statements here come from the ten reviewed stills, with official IWC facts kept in a separate comparison. A new exact-unit record should connect front, back number, controls, measurements, weight and tests without edit gaps.
IW371446 keeps the older 3714 family but changes the dial direction
The Portugieser IW371446 page is the closest same-generation alternative in this catalogue. Compare its blue-dial direction with this silver-white IW371445, then keep the two samples' measurements, backs, straps and QC results completely separate.
IW371601 moves to the later 3716 generation
The Portugieser IW371601 page offers a later-generation chronograph direction and is a useful comparison for caseback treatment and overall proportions. Do not transfer its movement, dimensions or sample evidence to the older-reference page.
IW358306 removes the chronograph controls
The Portugieser IW358306 page keeps a silver-white Arabic-numeral dress direction but replaces the two-register chronograph layout with small seconds and a single crown. Choose it for visual restraint, then review its separate warm-tone case and evidence limits.
Exact genuine-reference context was checked against IWC's official IW371445 history page and official Portugieser reference guide. Genuine specifications and replica photo evidence remain separate.

Official IW371445 vs. This Replica Photo Record
IWC's genuine IW371445
IWC lists a silver dial, stainless-steel case, black alligator strap, standard solid back, 40.9 mm diameter, 12.5 mm height, 20 mm strap, 18 mm buckle, 3 bar, automatic calibre 79350, 44-hour reserve, 28,800 VPH, 272 components, 31 jewels, minute-and-second chronograph, small hacking seconds and convex double-sided anti-reflective sapphire.
This IW371445 replica photo set
The photos support a broad silver-white chronograph-style face and steel-colour direction, but show a brown crocodile-pattern strap and transparent back. They add a 43.7 mm crown-side span, about 86 g and one timing screen. They do not prove the official materials, dimensions, calibre, parts, jewels, reserve, functions, crystal, pressure rating, origin or authenticity.

Same-generation blue-dial route
Portugieser IW371446
The closest catalogue companion keeps the older vertical two-register chronograph direction and changes the dial colour. Treat its own strap, back and QC record independently.
Later-generation chronograph route
Portugieser IW371601
This later 3716 direction is useful when comparing proportions and rear design. Its movement and measurements cannot be transferred to IW371445.
Simpler small-seconds route
Portugieser IW358306
This reviewed Automatic 40 sample removes the chronograph pushers and upper register, favouring a calmer dress-watch layout with its own warm-tone sample evidence.

Product, evidence and order questions
IWC Schaffhausen Portugieser IW371445 Replica Watch FAQ
What do the ten IW371445 photos confirm?
They show a silver-white vertical-register chronograph-style dial, warm-tone Arabic numerals and leaf-style hands, steel-colour case, crown and two pushers, brown glossy crocodile-pattern strap, deployant clasp, exhibition back with an automatic mechanical appearance, about 43.7 mm across the crown side, about 86 g, and one timegrapher screen reading -4 s/day, 258 degrees, 0.3 ms and 28,800.
What is the largest conflict with the genuine IW371445 specification?
IWC specifies a black alligator strap and a standard solid back for the genuine reference. The photographed replica sample has a brown crocodile-pattern strap and an exhibition back. Those differences are prominent configuration departures, not small photography variations.
Is the pictured 43.7 mm the case diameter?
It should not be presented that way. The caliper appears to cross the crown side, so 43.7 mm is best treated as a maximum horizontal envelope. IWC lists a 40.9 mm crown-excluded diameter for the genuine watch. Ask for a centred repeat on the main case body.
Is there a thickness measurement for this replica?
No. None of the ten still images measures case height. IWC lists 12.5 mm for the genuine watch, but that official figure cannot be assigned to the replica. Request a calibrated, centred crystal-to-back measurement on the exact unit.
Does the display back prove an IWC calibre 79350?
No. The photo shows a decorated automatic mechanical appearance with a full-size rotor and IWC-style wording. Layout and engravings do not establish calibre identity, 272 components, 31 functional jewels, origin, manufacture or service compatibility.
Are the chronograph functions proven by the two pushers?
No. The dial, two registers and pushers support a chronograph-style configuration, but still photos do not show start, stop, minute accumulation or zero reset. Request one uninterrupted demonstration with the dial in clear view.
What does the timegrapher photo establish?
It records one moment and one position at about -4 s/day, 258 degrees, 0.3 ms and 28,800. It does not prove long-term accuracy, several-position stability, power reserve, chronograph performance or the movement model.
Do 3 BAR and MADE IN SWITZERLAND-style markings prove the claims?
No. They are visible decorative or identifying text only. The photos contain no pressure result or origin documentation. Agree on any pressure test and the actual movement source separately.
Is the brown strap confirmed as Italian alligator leather?
No. The surface has a crocodile-pattern texture, and the underside carries IWC, MADE IN ITALY and DANG-style text. Texture and stamps do not prove species, country of manufacture, supplier or genuine IWC parts.
How do I order this IWC Portugieser replica?
Record IW371445, the silver-white two-register dial, steel-colour exterior, brown crocodile-pattern strap, deployant clasp, exhibition back and 6230401-style back number. Then request crown-excluded width, centred thickness, zeroed weight, exact movement name, complete chronograph operation, multi-position timing, reserve, crystal and any agreed pressure proof. The listed price is US$657 and a US$20 deposit starts sourcing and QC.
