What a fake IW545150 is
A fake IW545150 is a copy of the IWC Portofino Hand-Wound Eight Days. The code sits in the IW5451 family: 45 mm case, hand-wound caliber 59210, 192-hour power reserve, small seconds at 6 o'clock and a power reserve scale on the dial. Copies come in several grades, and price and finish separate them more than any single detail. Variant codes at the end of an IWC reference change with dial color, case metal and strap. Confirm the exact configuration with IWC or an authorized dealer, because public reference lists do not cover every code.
What the genuine watch does
- Caliber 59210, hand-wound, two barrels, 8 days (192 hours) of power reserve.
- 45 mm case diameter, sapphire crystal front and back.
- Power reserve indicator and small seconds; date on some variants.
- Case in stainless steel or 18k rose gold.
Test the reserve. Wind a real 59210 and it runs eight days. A copy with a stock hand-wound or automatic movement stops in 38 to 45 hours. Set the watch down and time it.
Points to inspect on a copy
Movement
Ask for a photo through the case back. Real IWC finishing shows Geneva stripes on the bridges, blued screws and an engraved plate. Cheap copies use plain or painted plates. A 192-hour reserve and a power reserve hand that tracks the true state of the mainspring are the hardest parts to copy.
Dial and hands
Look at the printed scale. On the genuine dial the reserve numerals and the seconds track sit at even spacing, and the appliques are solid gold. Copies show thick print, uneven spacing and flat chrome markers. The date aperture edge on the real watch is sharp.
Case and engraving
Reference, case and movement numbers are laser-engraved between the lugs on the real watch. Copy engraving is shallow and the font drifts. Case thickness matters: the 59210 fills the case, and thin copies hide a smaller movement under a spacer ring.
Price bands
Genuine steel IW5451 models sell used for several thousand US dollars, and rose gold versions run higher. Current listings set the number, and box and papers move it. Copy prices run from about 80 USD for quartz-driven pieces to 400 to 700 USD for higher-grade hand-wound copies. The main risk is a seller asking genuine money for a copy.
Questions to ask before paying
- Which movement is inside, and what power reserve does it hold?
- Are the photos of the actual unit you will ship?
- What is the return window, and who pays return shipping?
- Does the case back reference match the dial variant?
Care
A hand-wound copy needs the same treatment as any mechanical watch: wind at the same time each day, keep it away from magnets, service it when the rate drifts. Water resistance on copies is unverified. Do not swim with one.
