Short answer
"Fake IW329113 v5" is a seller label. It names a replica of an IWC watch in the IW3291 reference block and tags it as the fifth revision of that copy. The version number comes from the factory or the dealer. IWC does not put version labels on its references. Published IWC material does not confirm the string "IW329113," so treat that number as a listing detail and check it against IWC's catalog before you compare anything.
What v5 means in the replica trade
Replica factories run batches. Dealers label them V1 through V6 and higher. A new batch can change the case diameter, case thickness, dial print, date font, hand finish, crystal coating, bracelet end links, or movement. The numbering is not regulated by anyone. Two dealers can sell the same batch under different numbers. The same number from two dealers can describe two different watches.

Movement is the main version divider
IWC fits its own calibres. Current IWC pilot automatics use a calibre with a 120-hour power reserve. Most replicas run a Seagull, Miyota, or ETA-derived automatic with a 38 to 42 hour reserve. Test it: give the watch a full wind, set it down, and note the stop time. A stop near 40 hours points to a generic movement, not an IWC calibre.
Inspection points on a claimed v5
- Case. Measure diameter and thickness with calipers and compare to IWC's published specs.
- Dial. Check the date window position, the date font, and the print edge under a 10x loupe.
- Crystal. Anti-reflective tint shows as a blue or purple haze on many replicas.
- Caseback. Laser engraving sits flat. Milled or stamped text has visible depth.
- Bracelet. End link fit, clasp micro-adjust holes, and spring bar length are weak points.
- Weight. Steel replicas often weigh 10 to 30 g less than the genuine watch.
