Short answer
IW328050 is an IWC reference number. Replicas of IWC references sit in three tiers: budget ($80 to $150), mid ($200 to $350), and high tier ($400 to $700). Before you buy any of them, get the genuine spec sheet. IWC publishes case diameter, thickness, lug width, movement, and water resistance for each reference. A replica that misses the case diameter by 1 mm or the date window position by 2 mm does not match the original.
This guide does not confirm which IWC model IW328050 names. Confirm that at the source. A seller who cannot name the model, the case size, and the movement has not handled the watch.
Confirm the reference first
IWC reference numbers change with dial color, case metal, strap, and movement. One number equals one configuration. Two watches with the same case but different dials carry different numbers. Get the number from IWC or an authorized dealer, then compare.
Spec sheet to collect
- Case diameter in mm and thickness in mm
- Lug width in mm
- Case metal and finish: polished, brushed, or both
- Movement caliber number, power reserve in hours, beat rate in vph
- Water resistance rating in bar or meters
- Dial layout: date window position, subdial count, text lines
- Crystal: sapphire or mineral, domed or flat, coating on one side or both
Movement
High tier replicas of IWC Pilot's watches often use a clone of the ETA 2892 or a Seiko NH35. Many current IWC models use an in-house caliber. A clone will not match the winding feel, rotor noise, or beat rate. Most IWC automatics run at 28,800 vph. Ask the seller for the beat rate. A clone at 21,600 vph runs a sweep that looks different at the seconds hand.
Case and finishing checks
- Measure the case with calipers. Ask for a photo of the watch on a scale or in calipers.
- Check lug width against the strap. A 20 mm lug with a 19 mm strap leaves a gap.
- Inspect the crown. Genuine crowns are signed and screw down with a defined stop.
- Check caseback engraving depth. Laser etching is shallow and grey. Milled engraving is deeper.
Dial, hands, and crystal
Look at printed text under 10x magnification. Replica printing fills in on small fonts and sits high on the dial. Genuine printing sits flat and sharp. Lume plots should sit level with the dial surface. The crystal should show no rainbow tint under a lamp. Mineral glass and low grade sapphire show that tint.
Water resistance
A replica rating is not a measured value. Gaskets are the weak point. Do not swim with a replica unless a watchmaker pressure tests it first. ISO 22810:2010 defines what a water resistance rating means and how a watch is tested against it.
Price and red flags
Prices outside $80 to $700 for this reference point to a low grade movement or a scam. Red flags: no case measurements, stock photos instead of the actual watch, no return policy, payment accepted by wire or crypto and nothing else, and claims of Swiss manufacture. No replica is made in Switzerland.
Legal note for US buyers
US Customs and Border Protection can seize counterfeit watches at import. The trademark holder can also file a civil claim. Buying a replica carries risk beyond the watch itself.
