Short Answer

IW328026 is a reference number in the IWC 3280 block. That block belongs to the Pilot's Watch Mark XX, launched in 2022. Replica sellers use numbers from this block to label clone Mark XX watches. IWC does not publish a product page for IW328026 on iwc.com. The Mark XX references IWC lists run from IW328201 to IW328207. Treat IW328026 as a seller label, not a documented factory reference. Before you pay, compare the listing against the real Mark XX specs below.

Real Mark XX Baseline

  • Case: stainless steel, 40 mm diameter, 10.8 mm thick
  • Lug width: 20 mm
  • Movement: calibre 32111, automatic, 120 hour power reserve
  • Frequency: 28,800 vph, 4 Hz
  • Crystal: sapphire with antireflective coating on both faces
  • Water resistance: 100 m
  • Dial: black or blue, white numerals, date at 3 o'clock
  • Bracelet: five link steel with EasX-CHANGE, or leather and rubber straps

What Replica Builders Change

Most clones hold the 40 mm diameter and the 20 mm lug width. Thickness is the common tell. Many builds measure 11.5 mm to 13 mm because the movement spacer and caseback sit deeper than the original. Calipers on a genuine Mark XX read 10.8 mm.

Dial text is the second tell. Originals print IWC SCHAFFHAUSEN under the 12, and PILOT'S WATCH AUTOMATIC above the 6. Font weight, letter spacing, and ink height vary between clone batches.

Movement Tiers

  • Budget: Asian 2813, 21,600 vph, 30 to 36 hour reserve
  • Mid: Asian 2824 or 2836 clone, 28,800 vph, 38 to 42 hour reserve
  • Top: Sellita SW200-1 or SW300-1, 28,800 vph, 38 to 42 hour reserve

The calibre 32111 in the real watch runs 120 hours on a full wind. No clone movement reaches that figure. A listing that claims 120 hours on a replica is wrong.

Price Bands

Asking prices in the replica market cluster in three groups. Low tier builds sit near $80 to $150. Mid tier builds with a 2824 based movement run $180 to $320. High tier builds with a Sellita movement and a clone bracelet run $350 to $600. Price does not prove quality. Ask for photos of the movement, the caseback, and the dial at 12 and 6.

Water Resistance

Factory claims of 100 m on a replica carry no standard. Gaskets, case tube seals, and caseback threads vary. Do not swim with a clone unless a watchmaker pressure tests it first.

QC Checklist

  1. Measure diameter and thickness with calipers.
  2. Check the date window for alignment at 3 o'clock.
  3. Confirm dial text spelling and placement.
  4. Run the watch 24 hours and compare drift against a reference clock.
  5. Inspect end links for gaps against the case.
  6. Check caseback engraving depth and the reference number stamp.
  7. Wind the crown and test hand winding, hacking, and date change.

Listing Errors To Watch

Some sellers pair IW328026 with 43 mm dimensions or a chronograph dial. The Mark XX is time and date, with no subdials, at 40 mm. A listing that shows subdials under this number is mislabeled. Ask the seller which factory built the watch and which movement sits inside. If the answer is vague, buy elsewhere.
