The IW321801 is an IWC Schaffhausen reference number. A replica IW321801 is a copy made outside IWC's factory. It carries the same dial text and case shape. It is not an IWC product. IWC does not service it, and the brand does not supply parts for it.
What the reference number covers
IWC writes references as six digits after "IW". The first four digits mark the family. The last two mark the variant. IW321801 sits in the 3218 block. Published IWC spec sheets for this block are thin. Case diameter, caliber number, and production years for IW321801 are not confirmed on the current IWC site. Buyers who need exact figures should contact IWC.
Most watches in this block use a stainless steel case, an automatic movement, sapphire crystal, and a date window at 3 o'clock. Case sizes in the wider Ingenieur line run from 34 mm to 42 mm.
Parts a replica copies
- Case: 316L steel, brushed flanks, polished bezel.
- Dial: applied markers, printed minute track, date aperture.
- Hands: sword or baton shape, lume fill on the hour and minute hands.
- Bracelet: integrated link design with a signed clasp.
- Caseback: reference number, serial number, and case material stamps.
Movements in replicas
Most replica IW321801 watches ship with an Asian automatic movement. Common bases are the Seagull ST2130, the Hangzhou 6300, and clones of the ETA 2824-2. Beat rate is 28,800 vph. Power reserve runs 38 to 42 hours. Genuine IWC movements in this size class hold a longer reserve and use a decorated rotor. Replica rotor engraving is shallow, and the lettering weight differs from the original.
Tells to check
- Caseback text: font, spacing, and engraving depth.
- Date wheel: numeral font and alignment in the window.
- Crystal: anti-reflective coating on one face instead of two.
- Bracelet: loose end links and faint clasp engraving.
- Crown: soft edges on the logo relief.
- Mass: replicas run 10 to 20 grams light against the steel original.
Price bands
Replica IW321801 listings run from about $120 to $400. The low end uses quartz or a low-grade automatic. The high end claims a Swiss ETA or a clone with a decorated rotor. No replica holds resale value. Secondhand demand is close to zero.
