Answer first
A replica IW321846 is a copy of an IWC watch. IWC reference numbers start with IW and carry six digits. The number 321846 does not appear in current IWC catalogs. The base model is therefore discontinued, region-specific, or misquoted by the seller. Ask for the original reference, the case diameter, and the movement caliber before you pay. If the seller cannot name the base model, stop there.
Decode the reference number
IWC groups references by family. Numbers in the 32xx block sit in the entry and mid range. The final digits usually mark a dial or strap variant, not a different watch. IW321846 and IW321801 can be the same case with different straps. Treat the last two digits as a variant code.
Case specs to verify
- Case diameter in millimeters. Ask for a caliper photo on a flat surface.
- Lug width. Common values are 20 mm and 21 mm.
- Case material: 316L steel, grade 5 titanium, or gold plating over brass.
- Crystal: sapphire with anti-reflective coating. Mineral glass scratches at Mohs 6.
- Water resistance rating. ISO 22810 covers consumer watches. ISO 6425 covers divers watches tested to 100 m or deeper.
- Case thickness and lug-to-lug length. Both change how the watch sits on a 6.5 inch wrist.
Movement options
IWC three-hand replicas ship with one of four movements. A Miyota 9015 runs at 28,800 vibrations per hour. A Seiko NH35 runs at 21,600. A Hangzhou or Seagull clone runs at 28,800. A Swiss ETA 2824 clone runs at 28,800. Ask which movement is inside. Beat rate decides the sweep of the second hand.
Chronograph builds use a 7750 clone. The 7750 places running seconds at 9 o'clock and a 12-hour counter at 6. Pusher feel is the tell. A stiff pusher that does not snap back on reset points to a low tier movement.
Dial and hands
Genuine IWC dials use applied indices with polished edges. Lume plots sit flush with the dial surface. Under a 10x loupe, look for misaligned date windows, uneven lume fill, and a seconds hand that rides too high above the dial.
Bracelet and strap
Steel bracelets use solid links on top tiers and folded links on low tiers. Check screw pins versus push pins. Screw pins cost more and hold tension longer. Leather straps vary by grain and stitching density.
Price tiers
- Under $80: quartz or low grade automatic, mineral glass, folded links.
- $120 to $250: NH35 or Miyota 9015, sapphire crystal, solid links.
- $300 to $500: Swiss clone movement, better case finishing, closer dial print.
- Above $500: near-spec builds with tighter tolerances.
Quality checklist
- Request a video of the second hand. Count the ticks per minute if possible.
- Request a movement photo with the rotor and balance visible.
- Confirm the crystal material in writing.
- Confirm the return window in days and the return shipping cost.
- Confirm the warranty length on the movement.
Legal note
In the United States, importing or selling a watch that carries a counterfeit brand mark is trademark infringement. Customs officers can seize shipments. A personal-use purchase carries seizure risk and no manufacturer warranty. Repair parts for clone movements come from third party suppliers.
